List of Battery Connections?

Should we add a list? You know like series to parallel, series only, parallel only description?

[[ https://scontent-iad3-1.xx.fbcdn.net/v/t1.0-9/15741263_1151429451641121_1653540122186819546_n.jpg?oh=68169489afab475404a27d915b22fd2d&oe=58DE187B |24 to 12 series to parallel for electric scooters]]

Basically is it possible to do a series-to-parallel connection? ie a 48 volt motor going to a 48 volt.

The neg of the main terminal will go to the posi of the aa battery you want to recharge, the + of the aa battery will go to the negative of the 12 volt fan. Then you put the pos of the 12 volt fan to the main terminal. The main terminals in the pic are petruding out of the 3 battery cells. If you need to recharge an AA battery, and dont want to use the grid, this is the best option. 3 12 volt batteries. — Preceding unsigned comment added by 69.255.30.97 (talk) 18:59, 28 December 2016 (UTC)

This is a series to parallel circuit, there is a possible solution for a series-to-series-to parallel, and this is electromagnetism or perpetual energy. This solution is the way evs should be built. — Preceding unsigned comment added by 69.255.30.97 (talk) 19:02, 28 December 2016 (UTC)

Popularity Contest?

Organized by popularity?!?! Talk about POV issues. I came to read up on the differences between AAA and AAAA ... and had to wander all over the article to find the information. Here's a thought: all in one table, arranged by the "Most Common..." column (as it is now), and add an additional column for "popularity" (which could be scaled 1-10 or "common/not so common/rare", etc.). </whine> JimScott (talk) 18:35, 30 May 2016 (UTC)

I've never been in love with the separation into "common" and "less-common" groups, although I understand why it was done. And I'm not sure all the current rankings make sense - I suspect that N's or 2032's are more common (now) than the 4.5Vs in the common section. I suppose a few of things are possible:

(1) just eliminate the distinction and merge the tables (and I'm only talking about the first sections - common/less-common cyl/non-cyl/PP, I don't think it's practical to merge *all* the batteries into one table)

(2) add back refs from the "less common" tables (as is already done for PP3 and "Lantern (spring)")

or (3) do the merge as (1), but add forward links from a list of particularly popular sizes.

I think I'd lean towards the first option. Rwessel (talk) 19:09, 30 May 2016 (UTC)

I took a crack at this, except I also added an 'obsolete' section for anything no longer manufactured or used for legacy applications. --Skrapion (talk) 06:53, 21 June 2016 (UTC)

Combined 90v and 1.5v Valve Radio Batteries

There's no mention of these batteries on this page.

They used to have two sets of connections, one for the 90v HT line to drive the electronics and one for 1.5v to power the valve heaters. They were big things and heavy.

I've had a quick search and found some discussion about them here with a photo: http://www.radiomuseum.org/forum/philco_transitone_pt_63.html but I expect they're obsolete and not manufactured so I'm not sure how you'd handle them on this page.

I suspect there was more than one size.

They would go into the Obsolete batteries section. If you're putting a bunch of different sizes in, make a subsection, like the PP series. --Skrapion (talk) 20:09, 1 December 2016 (UTC)

Missing R10 cell type

R10 cell

Article mentions 2R10 batteries, but also a single R10 cell used to be available on market, for example in Poland during '70s and '80s there were Elektron brand R10 batteries like one on a photo. Tzok (talk) 14:07, 28 December 2016 (UTC)

A battery – Source of R23/LR23 designation for A-size battery?

I could not find "R23" on Barak's Electrochemical Power Sources (1980, ISBN 0906048265, makes reference to IEC's 4th edition of standard 60086-1, then simply called 86-1), nor I could locate it on the 10th edition of 60086-1 (2000). However, I do find "R51" on both sources I just cited, and its given dimensions (16.5 mm × 50.0 mm) are very tightly close to those (17 mm × 50 mm) given for the A-size battery in this article's table for cylindrical batteries. Shouldn't "A" have been specified here as R51/LR51 instead of R23/LR23? With no verifiable IEC source for "R23", the given designation can't be listed in the table under the column "IEC" (it should have been listed instead under the column "Other common"). All the other one/two-digit "R" designations under the IEC column in this table are present in both Barak and the IEC standard - only R23 is missing. 74.213.71.21 (talk) 00:55, 20 February 2017 (UTC)

Hey. Has anyone got any positive source of the size of the A battery? I have looked in the IEC and ANSI standards I have available to me but they're now a little old. And I have been informed that maybe the A size is no longer standardised so should probably be referenced elsewhere. As for the current picture of an A battery, I'm quite sure I have some somewhere so should update that picture. Umm, Saft still use A and R23 as a size for their lithium primary cells, but it would be better to have a non-manufacturer source. --Lead holder (talk) 09:24, 15 March 2017 (UTC)

Suggestion: Change mAh to mWh

The article is listing each battery's capacity in mAh, which is useless in comparison, because they all use different voltages. I suspect the author got the habit from cell phone battery discussions, which are always centered around mAh since they're almost always the same voltage. But really, it's like measuring a car's gas tank in height, when they're all different widths. A much more useful number to compare how much useable energy you can get out of each battery would be milliwatt hours. moeburn (talk) 17:17, 7 April 2017 (UTC)
