the copy of the specification I have is dated 2001, but I believe this is the most current. Yiming689 01:30, 24 April 2007 (UTC)
Why the designations "AA, AAA, C, D" ?
Each designation describes size. Rintrah 08:31, 3 November 2006 (UTC)
Two questions:
Which company introduced the AA battery (and when)?
Are there any other common names for this type of battery? During my childhood (in the UK) we always called them "HP7" batteries, though that name might have been specific to a particular manufacturer.
According to "List of battery sizes", its colloqiual name is Penlight Mignon. To answer to your other question, AA is the standardised definition set by the IEC (International Electrotechnical Commission)(source: http://www.bbma.co.uk/batterysizes.htm). I do not know which company first manufactured it. Rintrah 08:31, 3 November 2006 (UTC)
Why redirect "A Battery" to this article?
What is the point of having the "A Battery" redirect point to this article, when this article makes no attempt whatsoever to explain or discuss the "A Battery" type? I do see in the references an article for "A Battery (vacuum tubes)" which is the more logical redirect target, and so I'm changing the redirect to point to there.

Minimum Volts to Power Various Equipment
Calling the battery guy to write this up for everyone, please? Some years ago, Popular Science (maybe something related) ran an article explaining that various batteries, at least D,C,AA,AAA, had MUCH useful life for certain devices that required far less than a full 1.5V per cell was required for some devices, meaning that even when many were ready to dispose of them, there was substantial useful life. In other words, items with motors, lights, and high (important) memory devices--cameras, gps.....shut down and/or fail to work fully when the batteries are not far down from 1.5V. Save those batteries for clocks, clocks with sound chips (incl alarm clocks), as these will function with the "deadest" batteries. Pocket radios will work on very low voltage, too. AM requires far less power than FM, as it turns out. I have a ANR (automatic noise reduction) headset and the voltage required is FAR less than the full 1.5V (it works well, even when the little "on" light barely lights). Along these lines then, note that rechargeables at 1.2V maximums will QUIT in those devices where shutoff thresholds are high. Someone help to write this somewhat meaningful information in encyclopedia form, please? Note that this public service might reduce the number of batteries going to the trash...or perhaps delay the discard, thereof. Good luck! 207.178.98.4 03:58, 11 September 2007 (UTC)
I personally experienced devices not working powered by rechargeable batteries with 1,2 volts. Why do manufacturers not warn consumers that some electric devices cannot be run with rechargeables? Wkr, --Paunaro 09:50, 27 September 2007 (UTC)
