Why is there not a section and/or article on voltage sag and how to overcome the sag? Reddwarf2956 ( talk) 13:58, 9 January 2009 (UTC)
This is getting a little bit out of my area of expertise, but I found the stub article Electrical cell, and figured that it's a duplicate of a more thorough article. I found that Cell (electricity) redirects here, so it makes sense to me to merge that article into this one. Let me know what you think. Wizard191 ( talk) 18:49, 19 February 2009 (UTC)
User:King of Hearts has twice removed sourced statements on the largest and lightest batteries, [1] [2] claiming that such information is unencyclopedic, without further support. There was no attempt to counter the longstanding practice of measuring batteries by Wh/kg, which we do in our infoboxes and which establishes the substantial notability of battery mass. The largest installation is notable in its own right, as a measure of the success of a certain kind of cell. I recommend that if there are any actual reasons that this information be removed, that they be listed here so that they can be discussed. 69.228.209.174 ( talk) 08:18, 25 February 2009 (UTC)
Kang, B. and Ceder, G. (2009) "Battery materials for ultrafast charging and discharging" Nature 458: 190-3. 1:00-6:50 (audio) NCC-8765 ( talk) 05:16, 15 March 2009 (UTC)
My wall clock died and when I replaced the AA battery I found the negative terminal was covered in a yellow-tinged white mineral deposit, perhaps a crystallization of some sort. I am curious what the corrosion is chemically and why it occurred in this dead battery and not in others. I read a few internet forums and most of the wiki article on batteries I didn’t find a link to anything that explained white corrosion in the chemical section. I suggest that the article is slightly focused on an industrial perspective of batteries and could be more encyclopedic if it also connected with Wikipedia's body of chemical knowledge. —Preceding unsigned comment added by Pstaight ( talk • contribs) 15:44, 23 March 2009 (UTC) Following "also see" -> "Alkaline battery" -> "leak" I found that the white corrosion is probably potassium hydroxide and I'm assuming it was caused by a manufacturer defect. All in all it's a good article covering a tremendous amount of information maybe it could be a starting point for understanding chemistry, maybe all it needs is to have the word "alkaline" in the chemistry section link to the article on alkaline batteries. (also what is SineBot?)-- Pstaight ( talk) 16:05, 23 March 2009 (UTC)
I think this section could use a table describing the best way to treat specific battery types to extend their life.
A rough example. I'm not saying the information in the table is correct.
Battery Type | To Maintain Charge | Improves Life | Lowers Life |
---|---|---|---|
NiMH | Keep cool | infrequent discharges | deep discharges |
Car Battery (specific type) | keep it charged | ? | full discharges |
Mention in the article that besides metals, air-fuelled batteries also exist. See http://www.elektor.com/news/air-fuelled-battery-could-power-portable-devices.965568.lynkx —Preceding unsigned comment added by 91.182.189.205 ( talk) 10:44, 29 May 2009 (UTC)
Explain how batteries are rated and what the amp-hour designation means —Preceding unsigned comment added by 198.253.49.6 ( talk) 23:11, 2 October 2009 (UTC)
The result of the move request was page moved. ~~ GB fan ~~ talk 15:12, 9 October 2009 (UTC)
Battery (electricty) →
Battery (electricity) — Immediately, to fix this spelling error but ultimately to reverse a page renaming to an undiscussed and decidedly minority viewpoint. --

Battery (electricity) → Electrochemical battery — I request to move the article to electrochemical battery (page was moved a few days ago to this name, but was reverted as it is considered a controversial move). As there is already the article electrochemical cell, and a battery (in electricity) is simply a combination of these, it is only appropriate to move it here (article coherence). Also, a battery on itself could mean a variety of things (eg gun battery, ...) thus the "electrochemical" is crucial is this differs the article from the other "batteries" Electrochemical battery is btw not a "popular term", but no one would find battery (electricity) a popular term neither (I wouldn't think anyone would search for the article with this term) Thanks, KVDP ( talk) 06:41, 12 October 2009 (UTC)
User:KVDP has made a number of alterations to the article in line with the rejected change of title. The article needs to be reverted to the version timed at 6:05 6 October 2009 to remove the erroneous edits (and subsequent reverted vandalism). I don't know ho to do this but someone else may. -- 20.133.0.13 ( talk) 14:27, 13 October 2009 (UTC)
To avoid duplication of discussion, see the relevant discussion on lithium-ion battery discussion page. -- 20.133.0.13 ( talk) 14:38, 13 October 2009 (UTC)
Too little material about the photographed tester on this page.
Is it ok to assume the voltage measured at intensity zero is an indicator of the remaining charge?
What would be a typical load resistance to get a more accurate figure?

Rechargeable nickel-zinc batteries are now available from many sources, including Amazon.com. I think they should be added to the lists and mentioned in the write up. I would do it myself, but I would rather let someone who has already worked on the article do it. -- Dwane E Anderson ( talk) 13:12, 17 November 2009 (UTC)
"The lead-acid battery is also very heavy for the amount of electrical energy it can supply"
This is misleading at best. Whether you measure the amount of power over time, or the amount of current in a short time, the lead-acid battery is NOT 'very heavy' for its energy output. The only batteries that can put out comparable or greater electricity in the same weight and size are NiMh and Li-ion, the latter of which is still only experimental. The other battery types can not put out the bulk power of lead-acid batteries, so quoting their energy density is misleading.
The tables on batteries are quite inaccurate. For instance, lead acid batteries are said to be 'moderately expensive' while NiMh, NiZn, and NiCd batteries are said to be 'inexpensive'. They are decidly NOT inexpensive, they are all much more expensive than lead acid batteries. In the lead acid section it says they are inexpensive !
The batteries conatining Nickel produce large amounts of toxic materials in their construction, the table infers that they have no toxic properties. 203.26.122.12 ( talk) 05:18, 1 December 2009 (UTC)
The Dry Cell section is written poorly. Using phrases such as "any random position" and having a link to en.wikipedia.org/wiki/Dry_cell" which directs back to this article. Needs desparate updating. 124.149.55.3 ( talk) 07:43, 15 December 2009 (UTC)
