Talk:Alkaline battery

There is plenty of good simple science in batteries.

• Chemistry: ion flow, membrane properties and tradeoffs, redox potential
• Physics: energy density, capacity dependancies, internal resistance,
• History: lineage

Compare and contrast with Zinc carbon battery - article needed for this, and with Lighium battery too.

Bear in mind http://en.wikipedia.org/wiki/Battery_%28electricity%29

Voltage

Added "approximately" to voltage. An alkaline cell produces 1.58 volts. I'll have to look up carbon-zinc, don't know it off the top of my head. Rsduhamel 07:16, 28 Dec 2004 (UTC)

temperature limitations?

What are the temperature limitations on alkaline batteries? What happens when you exceed them? - Brewthatistrue 22:09, 23 Jun 2005 (UTC)

Goes boom and expells murcury gas...read the article...Kr5t 22:48, 21 May 2006 (UTC)

Where does it say anything about mercury gas? --Newton21989 01:55, 4 April 2007 (UTC)

Usage

Alkaline batteries are preferred for voltage sensitive electronic devices. The output voltage does not drop until totally drained of useful energy. Carbon-Zinc cell output voltage will consistently drop as energy is used which will result in erratic low voltage operation of electronic equipment, hence the alkaline requirement on most electronic equipment.

Environmentalism

What is the impact of modern alkaline batteries on the environment? The fact that there is no longer mercury added to them helps, being a heavy metal, but are there any other traces of heavy metals in alkaline batteries?

There still is mercury...Kr5t 22:48, 21 May 2006 (UTC).

However at the site: www. duracell.com it reads that they have not had mercury in their batteries since they voluntarily discontinued producing them with it in 1993. —The preceding unsigned comment was added by 67.142.130.40 (talk • contribs). 18 nov 2006

I'm not very familiar with battery recycling, but it seems that this would be something good to add. Maybe some guidelines on proper battery disposal too. Update: I added a link on battery recycling which I thought was informative. —The preceding unsigned comment was added by 71.117.254.131 (talk • contribs). 4 Aug 2006

Can anyone put these compunds into english please?

Self recharging

After letting used batteries sit for a while they seem to partially recharge (although it doesn't last long). How does this happen? What are the results, etc? Is it dangerous to use a battery up like this? Thanks --32.97.110.142 17:18, 7 March 2007 (UTC)

White crystals

Sometimes alkaline batteries leak, a clear fluid. But sometimes white crystal powder forms at one end. It seems to corrode contacts. What exactly is this white material, what exactly causes it, how can it be avoided, and what contact materials are most resistant to corrosion? -69.87.193.60 17:27, 22 March 2007 (UTC)

• I've had this happen many times while recharging alkaline batteries. This is potassium hydroxide and in my experience, has not seemed to cause any damage to myself or objects it comes in contact with. My advice, to be safe, is just wipe it up with a paper towel, or likewise and throw the battery (It's no good after it pops.) and the towel into a trash container.

Recycling

Information is needed about recycling and disposal practices for alkaline batteries, in various countries around the world. -69.87.193.60 17:27, 22 March 2007 (UTC)

Capacity and Current

There seems to be a contradiction between the Capacity section saying that loads of 1000mA can reduce the energy content due to internal heating and the Current section saying that a AA battery can deliver 1000 mA without significant internal heating. Am I missing something? --Nathan24601 (talk) 20:50, 24 February 2008 (UTC)
