edit·history·watch·refresh Stock post message.svg To-do list for Battery (electricity):

It would be good to include this reference and accordingly update C-rate chapter. Please, if somebody thinks that this comment should go somewhere else, do so and replace it. The reference is: http://www.starkpower.com/highratedischarge.html. The description of C-rate seams confusing. It doesn't clearly state that for example at 2C discharge rate the battery would hold two times less.

bad reference[edit]

that "sugary drink" cellphone doesn't exist. it's a just a design concept. —Preceding unsigned comment added by 98.164.102.214 (talk) 11:19, 14 July 2010 (UTC)

Inside?[edit]

what is inside a battery —Preceding unsigned comment added by 97.104.18.106 (talk) 01:41, 12 January 2010 (UTC)

A battery is an electrical/electrolytic circuit consisting in 1 or more electrochemical energy producing cells. And they all have 5 essential constituent ingredients. 2 of these are the electrochemical energy powered EMF voltages. 2 more are electrical resistance networks related to the transfer of the electrons into and out of (and within) the cell electrical circuits. And the fifth is an electrolytic ion motion of flow of the ions in the electrolyte in the direction of the dominant EMF voltage gradient. Since the primary purpose of a battery is to supply electrical energy to an electrical load, these constituents may be considered to be the following listing of a series connected electrical entities:
     1 A dominating negative electromotive EMF (at the point of electrochemical activity)
     2 The electrical resistance of the negative anode circuit
     3 The flow velocity of the ions within the electrolytic circuit
     4 The usually counter EMF voltage at the point of electrochemical activity within the cathode
     5 The electrical resistance of the cathode circuit

These constituents work together to provide the composite battery unit with an electrical energy power and energy supply characteristic intended to meet a certain set of specified electrical power and energy load requirements.WFPM (talk) 00:00, 9 March 2013 (UTC)

Proposed article name change: 'Battery (electricity)' to only 'Battery'[edit]

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section.

The most common popular usage of 'battery' in Wikipedia, by far, is for this article on the electrical battery, with the legal and military definitions trailing in that order, as listed on the 'Battery (disambiguation)' page.

This article is a highly read page, with more than 116,028 pageviews last month -the figure likely being over 123K pageviews since the server didn't record two days worth of data. That volume of readership compares with the second place 'Battery (crime)' figure of approx. 16,777 views, and the third place article 'Battery (military)' of approximately only 27 pageviews.

Since the second and third place articles combined amount to less than 15% of the readership of the electrical battery article, it would be preferable, i.m.h.o., to rename this article to plain 'ol Battery, with a corresponding renaming of the disambiguation page 'Battery' to 'Battery (disambiguation)'. The net result of such an article name change would be to make this article's webpage more quickly accessible to the casual viewers seeking information on electrical batteries (approximately 85% of the total pageviews for all 'battery' articles). The tophat note would also be revised to include some extra elaboration for the legal and military articles.

Prior to posting a formal name change proposition tag on this article's page, a survey of regular editors to capture opinions and or other comments would be helpful. Best: HarryZilber (talk) 15:03, 10 February 2010 (UTC)

Oppose. Page views don't count. If a hundred thousand can find the page each month, obviously the name works. --Wtshymanski (talk) 17:40, 10 February 2010 (UTC)
Saying that 100,000 people found their way to an article with a tricky name means little. If you really need something of importance, you'll go after it irregardless of the obstacles, or in this case tricky names. What we're discussing here is how to make life simpler for those 100,000+ people who need this information every month. I propose we do the name change and watch, and if the monthly stats for this article goes down, then the name change can always be undone. Best: HarryZilber (talk) 02:00, 16 March 2010 (UTC)

Wh/kg[edit]

Wh/kg redirects here but no definition is given. —Preceding unsigned comment added by 165.228.240.251 (talk) 23:59, 4 March 2010 (UTC)

Rating? Why mAh not Wh?[edit]

Why are batteries almost always rated in current-hours -- mAh, not power -- Wh or joules? I can always multiply volts by mAh to get mWh, but why is current-time the standard? I assume it is somehow a more reliable measure (maybe at low temperature the voltage drops but the number of electrons ready to flow doesn't?) The fact that "Watt" doesn't appear on this page tells me that there is some fundamental reason Watts just don't make sense for batteries. —Ben FrantzDale (talk) 14:00, 8 June 2010 (UTC)

I've always seen Ah in supply and Wh in consumption and J in science. The battery industry uses mAh so that would be a good reason to use that here. 76.66.193.119 (talk) 09:15, 31 July 2010 (UTC)
Years later...I've seen some rechargeable lithium-ion batteries have watthour ratings stamped on them; and some air transport regulations are phrased in terms of the maximum watthour capacity of lithium batteries that can be transported. --Wtshymanski (talk) 20:41, 4 January 2012 (UTC)
First note that these are two different units. Amperes (A) is coulumbs of charge (C) per second (t), A = C / t. Thus mAh is essentially a measure of charge, or coulombs. Watts (W) is joules of energy (J) per second (t), W = J / t, thus Wh is essentially energy, or joules. But to answer your question, because batteries primarily store charge and not energy. Randy Yates, Eaton Corp., 10:39 EST, 20-Aug-2012.
So if batteries do not primarily store energy, what is it that lights up the bulb in my flashlight? 86.144.90.137 (talk) 15:18, 9 September 2012 (UTC)
@BenFrantzDale: @Randy Yates: @86.144.90.137: It is wrong to say that "batteries primarily store charge and not energy". It is the opposite. Energy is one of the most fundamental concepts in science. Basically, everything has energy. Charge, on the other hand, is a way to understand and explain energy in certain physical interactions, like in electricity (electric field, electrostatics, electrochemistry). In general, "charge" is a measure of energy. The more charge you can store, the more energy. They are proportional. As to why in batteries Ah is used. It may have to do with the practical aspects of charging and discharging. A battery of 50 Ah can be discharged in one hour by using a current of 50 A. So, if I have a device that consumes 5 A, a battery of 50 Ah will power it for 10 hours. I guess it is simpler to understand it this way, because we can measure current with ammeters and clamps, instead of knowing exactly how much energy (Wh) this device will need for a certain period of time.----137.132.22.190 (talk) 02:26, 4 August 2014 (UTC)

American invention?[edit]

Why is Benjamin Franklin mentioned first if he is not the originator/inventor? It's almost if you are claiming the battery as an American invention —Preceding unsigned comment added by 87.218.232.86 (talk) 09:12, 11 July 2010 (UTC)

Benjamin Franklin is just the name associated with the first naming of electrical battery. Knowledge of battery-like things existed in antiquity, and it is not clear clear what should be defined as the first battery. Who do you think can be named as the originator/inventor? --SmokeyJoe (talk) 21:55, 11 July 2010 (UTC)
I think Benjamin Franklin invented the forerunner from the Battery. Also interesting is the PC-Adventure-Game "Day of the Tentacle". Benjamin Franklin is into the Game and invented the Battery! — Preceding unsigned comment added by 93.232.54.208 (talk) 00:47, 13 February 2013 (UTC)

Propose article rename to "Electrical battery"[edit]

The following discussion is an archived discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

The result of the move request was: no consensus to move page. As in previous cases, the case that this is a strong primary topic for the term "battery" is not convincing a consensus of editors. Meanwhile, the world keeps on turning... - GTBacchus(talk) 03:21, 6 August 2010 (UTC)



Battery (electricity)Battery — Administratively closing no consensus to move "Battery (electricity)"→"Electrical battery", but resetting/relisting for later alt proposal that seems to have some traction. DMacks (talk) 06:57, 21 July 2010 (UTC)

{{movereq|Electrical battery}}

  • Moved from the uncontroversials: move to 'Electrical battery'? Anthony Appleyard (talk) 13:32, 12 July 2010 (UTC)

Battery (electricity)Electrical battery — I propose to rename this article to "Electrical battery".
Reasons:

  • "Electrical battery" was the phrase used in the first records of the naming of such devices
  • "Electrical battery" has remained stable in the opening sentence for a long time (several months).
  • The use of parentheses does not seem right for a common use item.
  • The typical reader would be comfortable with the term "Electrical battery". --SmokeyJoe (talk) 22:01, 11 July 2010 (UTC)
  • This should probably be nominated at WP:RM to get additional input. Especially given the fact that the previous discussions were nominated there. Vegaswikian (talk) 05:06, 12 July 2010 (UTC)
I don't see what this has to do with disambiguation, nor do I see anything directly relevant at WP:COMMONNAME? --SmokeyJoe (talk) 14:11, 12 July 2010 (UTC)
  • Oppose. "Electrical battery" is a construct designed to eliminate the parentheses, but people do not commonly say "electrical battery" in conversation and they write it but rarely. Why disturb this version for a rarely used one? By far the most common name is simply "battery", and the parenthesis modifies that. Let's stick with the parenthetical name: Battery (electricity). Binksternet (talk) 15:13, 12 July 2010 (UTC)
  • Support: Electrical battery seems natural and avoids the parentheses. A good comparison might be association football. I would also support a move to just battery as this article is surely the primary topic. Iota (talk) 17:18, 12 July 2010 (UTC)
  • Recommended alternative: As discussed previously above, this article, 'Battery (electricity)', should be changed to only 'Battery'
The most common popular usage of 'battery' in general, by far, is for the electrical battery, with the legal and military definitions trailing in that order, as listed on the 'Battery (disambiguation)' page.
This article is a highly read page, with more than 116,028 pageviews several months ago. That volume of readership compares with the second place 'Battery (crime)' figure of approx. 16,777 views, and the third place article 'Battery (military)' of approximately only 27 pageviews.
Since the second and third place articles combined amount to less than 15% of the readership of the electrical battery article, it would be preferable, i.m.h.o., to rename this article to the simplest form 'Battery', with a corresponding renaming of the disambiguation page 'Battery' to 'Battery (disambiguation)'. The net result of such an article name change would be to make this article's webpage more quickly accessible to the casual viewers seeking information on electrical batteries (approximately 85% of the total pageviews for all 'battery' articles). The tophat note would also be revised to include some extra elaboration for the legal and military articles.
Those wanting to simply life for the greatest number of people will likely find this suggestion compelling. Best: HarryZilber (talk) 16:49, 12 July 2010 (UTC)
  • Binksternet, it is not helpful to say that nothing has changed. The past discussions were strongly focused on moving this page to "Battery". The Archive_2 links are not even relevant (concerning a spelling mistake, and a suggestion contrary to WP:COMMONNAME). The Talk:Battery link is either unclear in relevance (a few participants in a conversation spanning four years) or again reflecting consensus against moving this page to "Battery". --SmokeyJoe (talk) 06:01, 19 July 2010 (UTC)
That list is a complete list of move discussions, all-inclusive for completeness' sake. Of course, the misspelling move was uncontroversial. However, I see a direct connection between the current proposal to move this article to "electrical battery" and the past one suggesting "electrochemical battery". What I mean by "nothing has changed" is that nothing in common battery terminology has changed since these past discussions. The leader in Google searches is still the battery which supplies electricity, and this page is the most-viewed battery article on Wikipedia. Battery (assault) is still a prevalent legal term and battery (artillery) is still a prevalent military term. Battery (baseball) is still an archaic usage. Binksternet (talk) 15:12, 19 July 2010 (UTC)
  • The assertion that "electrical battery" is the common name is quite plainly false. There's nothing wrong with parentheses where there's a very obvious common name which requires them. The analogy made to association football falls down because at least there's a definitive official title to use as the name. Chris Cunningham (not at work) - talk 23:59, 13 July 2010 (UTC)
  • Oppose the move as nominated. Battery is the most common name it should remaias the name of the article. That said, I think the page should be moved. I believe this type of battery is the primary topic. The page hits quoted above seem to point to this being the primary topic also. If this is the primary topic it should be at the un-disambiguated name Battery and the disambiguation page should be at Battery (disambiguation) ~~ GB fan ~~ talk 12:25, 14 July 2010 (UTC)
  • More comments
  • Having looked up Britannica (1965), I find, as expected, that the only article under battery is the electrical battery (and types, such as atomic). I'd have preferred to move this article to "Battery" as it is the primary topic in modern popular usage, but I accepted the previous discussion that went against that proposal March 2006, March 2008. Personally, I note that the word derives from a broader meaning (something like "similar things that are used similarly, with force", whether a battery of punches used in battering someone, a coordinated assault, a group of large guns to be used in a coordinated assault, or an array of cells used together additively to produce a significant electromotive force).
  • I dislike parentheses because they are not usually used in professional publications where a more accurate title can equally be used. Apparently not everyone dislikes parentheses. In essence, this move comes downs to a preference concerning parentheses. If we must stick with parentheses, I would prefer "Battery (electrical)".
  • Noting Chris' objection, the equivalent of a definitive official title to use would come from the first description of the device, by Benjamin Franklin, which is the "electrical battery". --SmokeyJoe (talk) 04:56, 19 July 2010 (UTC)
  • Further Comment: I believe there's significant interest in the proposal to change the current title 'Battery (electricity)' to the prime topic 'Battery', and move the disambiguation page to 'Battery (disambiguation)'. Although some areas of the world might refer to an 'electrical battery' in the first instance of mention, the use of the plain 'battery' appears by far the most popular usage worldwide. A quick Google check shows only 1.2M usages of "assault and battery", and only 32,000 usages of "criminal battery", versus about 140M usages or so of battery as an electrical component -which occupies the top ten results (not counting a news item). Yes, Google checks are non-binding on these discussions, but they're a good reality check for what's used on the web. While some might prefer more technical terms such as 'Electrochemical battery', I believe most interested editors would be able to live with the plain 'Battery' for the primary topic, accompanied by the normal hatnotes and disambiguation page. I would urge editors to allow this change (to just 'Battery') to move ahead and improve the title on what's plainly a highly viewed article on Wikipedia. HarryZilber (talk) 15:57, 19 July 2010 (UTC)
Suggested tophat notes:
"This article is about the electrical device. For the criminal term, see: Battery (crime). For the military term, see: Artillery battery. For other uses, see: Battery (disambiguation)."

New proposal to rename this article as the primary topic 'Battery'[edit]

Administrator's note: formal WP:RM proposal is now changed to rename to "Battery" (i.e., primary topic). No need to restate your same opinions if you commented on this one above. DMacks (talk) 06:57, 21 July 2010 (UTC)

Battery was 7676.
Battery (electrical) was 141.
Battery (crime) was 6769.
Battery (electricity) was 38103.
Artillery battery was 2927.
Are there better traffic numbers out there? Glrx (talk) 22:20, 21 July 2010 (UTC)
  • Oppose. I am not comfortable concluding that Battery (electricity) is so dominant that it should be [WP:PRIMARYTOPIC]]. Glrx (talk) 16:32, 24 July 2010 (UTC)
  • CommentOpposeIt is utterly and demonstrably incorrect to claim that "Electrical battery" was the term used initially for a device which creates electric current electrochemically. See the citations from the 1700's for "electrical battery" at Google Books: [1]. It referred to a set of Leyden jar capacitors connected in parallel. In the early years after the Voltaic pile was discovered "Electrical battery" still referred to a set of condensors, as shown by [2] from 1801 and [3] from 1805. The Voltaic "pile" versus condensor "battery" distinction was still made in 1830 and after, although some started calling a pile a battery. In 1830 Noah Webster used the military and legal definitions first, and the pile definition last, preceded by the condensor definition. "Electrical battery" still meant either device in 1859 and in textbooks many years thereafter. The proposed move is a solution in search of a problem. Most users are not going to type in "electrical battery" when they want information about electrochemical sources of electricity. The present title is fine. Edison (talk) 20:17, 24 July 2010 (UTC)
Edison, could you rephrase your point in relation to the first reference, in the first sentence, of the article, perhaps in a separate section. I think it is true that Franklin's "Electrical battery" was not electrochemical, but no one said it was. --SmokeyJoe (talk) 04:00, 25 July 2010 (UTC)
Comment - from your oppose it sounds like you are opposing the old proposed move; [[Battery (electricity) -->> Electrical battery. The discussion changed above, we are now discussing moving Battery (electricity) -->> Battery and Battery to Battery (disambiguation. ~~ GB fan ~~ talk 02:55, 25 July 2010 (UTC)
  • OpposeI oppose the garbled and confusing way this proposed move is presented, on procedural grounds, since the header and start of the section propose one move (to electrical battery") then it changes to a different proposed move, to "Battery." I oppose the move described in the header, since "electrical battery" is neither the original name of the device nor the most common descriptor today as an electrochemical source of power. I oppose the new move to "Battery" since the electrical usage is not that much more common than some other usages in published sources found at Google Books. Besides the electrochemical device (1.26 million results at Google Books) there is the widespread artillery use (914000 results at Google Books), usage as a crime (189000 results at Google Book), and even the baseball use (45000 results at Google Books). No encyclopedic purpose is served by the move. Edison (talk) 16:15, 28 July 2010 (UTC)
  • Comment: The suggestion to move this page to Battery would also involve moving the disambiguation page, presumably to Battery (disambiguation). A notice should have been placed on the disambiguation talk page, to advise users of the potential move; without such a notice, anyone who was watching the disambiguation page but not this article may be surprised to find the disambiguation page relocated completely without warning (if that were the outcome of this discussion). This is why there are separate directions at WP:RM for moves involving multiple pages. I have now placed such a notice at Talk:Battery. Propaniac (talk) 16:51, 27 July 2010 (UTC)
  • Absolutely support that this article is the primary topic for the word battery and should be moved there. SchmuckyTheCat (talk)
  • Oppose. The crime battery and the artillery battery are still prominent in usage—not so much less than the chemical storage of electric charges. Binksternet (talk) 18:03, 27 July 2010 (UTC)
  • Further comment: Yikes!! Is there somewhere to go to nominate this {Moverequest} discussion as the most confusing in WP's history?? To clarify the above:
    • this article would be renamed from 'Battery (electricity)' to 'Battery' ,
    • the existing disambiguation page 'Battery', would be renamed to 'Battery (disambiguation)'
Again, everyone, please remember that article titles should reflect popular usage. This article is the most sought after topic when people refer to or search for 'battery', so I encourage all to put their own personal preferences aside in order to help casual users and laypeople searching for information. Every single extra step that such users have to go through to find useful information will discourage a certain percentage from reaching their goals -and please let's not be cynical about that. If the great majority of users are looking for info on this topic, we should let them get to their goal with the simple single word search term 'Battery'. HarryZilber (talk) 17:58, 3 August 2010 (UTC)
The above discussion is preserved as an archive of a requested move. Please do not modify it. Subsequent comments should be made in a new section on this talk page. No further edits should be made to this section.

Introduction: enlarging the initial definition to include one-cell devices like the AA battery[edit]

Since most batteries now in use have only a single electrochemical cell (e.g. AA or C batteries, as opposed to the multi-cell 9 volt battery or the 6-cell 12 volt car battery) I have changed the first sentence to say,

"An electrical battery is device consisting of one or more electrochemical cells used..."

The history section further down explains this current meaning, and how it arose despite the original sense of battery as a multi-cell device like the voltaic pile.CharlesHBennett (talk) 22:05, 11 August 2010 (UTC)

I restored the more than one cell as the primary definition: dry cells, AA cell, 9V battery, car battery, and laptop battery. I don't believe the distinction should disappear right now, but others can weigh in. Glrx (talk) 01:20, 12 August 2010 (UTC)
Including the excluded case makes an encyclopedia article internally inconsistent.
It looks rather stupid for an encyclopedia article to say "An X is only yin. X also includes yang." If I walked into my local Canadian Tire and asked for a dry cell, I'd probably be put in the room they use to hold shoplifters. Everybody calls that AA or D thing a "battery" and it serves no encyclopediac purpose to be more pedantic than the world.Is the purpose of an encyclopedia article to show how much smarter we editors are than the great unwashed, or is the purpose to provide (as neutrally and verifiably as this Rube Goldberg process can) the facts? If anyone with even less life than I thinks the distinction between 1 cell and many cells is that important, research it and show how the usuage has changed since the 17th century. --Wtshymanski (talk) 13:51, 12 August 2010 (UTC)
agreed  — Preceding unsigned comment added by X-179 (talkcontribs) 00:51, 30 December 2011 (UTC) 
A single cell is not a battery, and Wikipedia should not sacrifice correctness just to cater to widespread misconceptions. An appropriate formulation could be "A battery is an arrangement of multiple galvanic cells; however in colloquial English, the term 'battery' is often used incorrectly to denote a single cell." — Preceding unsigned comment added by 27.96.110.66 (talk) 10:28, 17 October 2013 (UTC)

Parthain Battery[edit]

Wtshymanski - I'm curious; why don't you think that the Parthian Battery is suitable for inclusion in this topic? (And for the record, nope, didn't get it from the discovery channel). Fleetingshadow (talk) 05:50, 7 November 2010 (UTC)

Because it's not a battery. See Baghdad Battery. Or, at least, the connection with modern batteries is so speculative that it doesn't serve the modern reader well to make any fuss over this artifact. --Wtshymanski (talk) 14:28, 7 November 2010 (UTC)
Any way I can convince you to at least provide a link in the See Also section to the Parthian Battery so that people who are curious could find out more? My own take on this is that it may be a curiosity, but it's also possibly a valuable milestone in our scientific history, and a great reminder that not only does a lot of reinvention go on over the millennia, but that civilization is not bulletproof. (eg. The Antikythera Device)

Fleetingshadow (talk) 00:34, 13 November 2010 (UTC)

It does not belong at See also. Binksternet (talk) 04:54, 13 November 2010 (UTC)

Proposed navbox[edit]

What do you think so far? It covers battery types, parts, sizes and brands and would supersede both Template:Battery sizes and Template:GalvanicCells. --Schala 04:10, 15 December 2010 (UTC)

proliferation of redundant BMS/balancing articles[edit]

I happened across a couple of articles on related topics that I think should be merged, but my merger proposal on those pages hasn't generated much attention, so I want to call attention to the issue here.

Principles of Operation[edit]

This section seems a bit esoteric. My eyes started crossing almost immediately. I was surprised that several concepts I expected to see were not there. So, here is my thoughts: I have a bit of trouble with the first sentence; converting chemical energy directly to electrical energy. Not that it isn't true, but it isn't clear to me what that means. "Chemical energy" seems way too abstract, and in point of fact, it is a specific kind of chemical energy that is used. So, the term is too general and not useful. Also, while there is a lot said about the two half-cells (separation, etc. etc.), the point is not made that a battery works by separating a spontaneous redox (chemical) reaction into two halves and forces the electrons to flow through an electrical circuit to complete the reaction rather than what they would normally do (react "directly"with , "flowing directly" from oxidant to reductant (ignoring solvation shells, etc.)). A battery harnesses the energy of the chemical changes to do work by putting the work in between the two half-cells. Perhaps this is just my chemical background, but it just seems more intuitive than to talk about half-cell reactions. I was also surprised that the word "ion" was not explained, nor electrolyte. Perhaps there is just too much introductory material I am expecting, but it seems that it is less important that the reader know the name of a negative ion (anion) than they know that the ions carry the electrons which do the work. How about this proposal: "A battery is a device that converts the energy of a redox reaction directly to electrical energy. A redox reaction is a chemical reaction in which one chemical loses electrons (the oxidant) and one gains them (the reducer). A battery works by separating the oxidizer and reducer into two parts (half-cells) and forces the electrons lost by the oxidant to move through an electrical circuit (and do work) in order to get to the reducer and so complete the chemical reaction." Since the article does not allow editing, I leave this as a proposal. Does it help ?173.189.75.206 (talk) 17:00, 5 March 2013 (UTC)

If you register a pseudonym, you can edit. Aren't all chemical reactions "redox" reactions? Is "chemical" energy a really esoteric concept that needs much amplification here? We can talk about ions and redox and such later on in the article as necessary. If you have to define " a 'foo' is a 'bar baz grault'" in the first use of a term, it's probably too dense and should be rewritten to give the reader a better run at the concept. We don't want the readers' eyes to glaze over before they've even found out what is in the article. --Wtshymanski (talk) 17:57, 5 March 2013 (UTC)

AgZn 'mysterious' reaction[edit]

Why is AgZn said "Reactions are not fully understood." under here? Could someone please clarify?

Thanks.

Link between charge level and bounce height of dry cells.[edit]

Interesting video that I would not take seriously if it weren't from a vlogger I am familiar with.

http://www.youtube.com/watch?v=PRf9JTg3QwA

Not encyclopaedia material but I wonder if any studies or such have been done on this at all. It's interesting at least although has no practical use.

--Lead holder (talk) 09:56, 15 August 2013 (UTC)

An easy method of telling charged batteries from discharged batteries is of no practical use? Call me Mr Skeptical, but I didn't believe it. Snopes claims it is an urban myth. So I decided to try it, and to my astonishment, the batteries behave exactly as shown in the video. I even tried it with AA and AAA size batteries and it still works. I found a few forums where people tried to explain the reason with one 'genius' claiming that the batteries loose electrolyte as they discharge and therfore become lighter. Apart from the fact that he totally failed to explain where this mass disappears to, the electrolyte takes no part in the reaction of an alkaline battery. We can't put this in the article of course, because this is just original research at present. But the difference is so marked that it must be documented somewhere.

Anode & Cathode confusion?[edit]

The sign(+/-) is exchanged in Operating principle section Sandipk100 (talk) 11:39, 12 October 2013 (UTC)

No they are not. In a primary battery, the anode is the negative electrode and the cathode the positive. Have a look at anode and cathode to see why they are correct. Personally, I believe that the terms 'anode' and 'cathode' only serve to confuse readers in articles on electrochemical cells and batteries. This is especially so in rechargeable batteries because the anode and the cathode change ends between charge and discharge. I B Wright (talk) 11:55, 17 October 2013 (UTC)

Article Title Change[edit]

Technically, shouldn't the title be "Battery (electrochemistry)" instead of "Battery (electricity)"? Sure batteries produce electricity, but so do other devices. Chemistry is the method of production of electricity in this technology. --71.10.146.139 (talk) 23:37, 14 October 2013 (UTC)

The part in the brackets is there to distinguish this particular kind of battery from other types, such as artillery batteries; hence the disambiguation link. Article titles do not have to provide precise categorizations (Batteries of electrochemical cells are already categorized appropriately); Wikipedia has other mechanisms for that (arguably the Category:Battery_(electricity) could be changed. --Nczempin (talk) 00:42, 15 October 2013 (UTC)

Memory effect[edit]

The words in this section state things that the supporting link does not say at all. In fact the link supports conflicting information the NiCd article. I was going to completely rewrite this section, but as I am not an expert on this, I have to give the benefit of the doubt that whoever wrote that knows at least something more than I do. Also to be fair, the references in the other article aren't all that stellar either. Maybe I'll try to go find something more academic. In the mean time, I'm going to just put a "see also" link there. At least others can be as confused as me at the conflicting statements.Autumn Wind (talk) 15:05, 17 October 2013 (UTC)

Like Charges Should Repel, Opposites Should Attract[edit]

Please alter this statement to "One half-cell includes electrolyte and the negative electrode, the electrode to which anions (negatively charged ions) migrate" to "One half-cell includes electrolyte and the positive electrode, the electrode to which anions (negatively charged ions) migrate" because the previous sentence states that like charged particles are attracted to like charged electrodes which is incorrect.

Semi-protected edit request on 6 September 2014[edit]

Please change "An electric battery is a device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy." to "A battery is a device consisting of two or more electrochemical cells connected in series." The author of the Wikipedia page "Electrochemical cell" also confirms that a battery contains more than one cell and this is specified in parentheses at the end of the second sentence. I have also cut down this sentence as it was unnecessarily verbose. 124.190.92.221 (talk) 13:59, 6 September 2014 (UTC)

Not done:. Usual usage calls one or more cells a battery. Cells may be in parallel, too. --Wtshymanski (talk) 01:43, 8 September 2014 (UTC)

The lay person may refer to a battery as one or more cells but this is not the correct definition. This author gives one of the better explanations that I have seen http://www.gcsescience.com/pe1.htm. If you had two sets of cells in parallel this would be two different batteries and this is why I only described a battery as cells connected in series. The current trend in physics (and more specifically electricity) is that a battery is multiple cells in series and I think it is important that Wikipedia reflects the status quo in this field.

I propose this as the opening paragraph as it explains both sides of the argument:

"A battery is a device consisting of two or more electrochemical cells connected in series. However, in every-day usage a single cell is often also referred to as a battery. Each cell contains a positive terminal called a cathode and a negative terminal called an anode. Electrolytes move through the internal circuit to balance the build up of charge which allows electrons to continuously flow through the external circuit and perform work." — Preceding unsigned comment added by 124.190.92.221 (talk) 05:12, 14 September 2014 (UTC)
