Story: Dead iPod syndrome - no volt found?

1. 2500mAh means that when you draw current at the recommended rate, usually 10% of the battery capacity (in this case 250mA) then the time before the voltage falls below a predefined limit multiplied by the current should equal 2500. If you tried to draw 2.5A from a 2500mAh battery it would almost certainly overheat long before 1 hour.

2. You may not be aware that some devices such as DECT phones have turned away from custom battery packs to standard NiMH AAA batteries. Another advantage of this is that in an emergency alkaline batteries can be used (but not of course recharged).

3. There was a campaign some time ago to standardise power bricks - many devices are now thrown away because the power brick is broken or lost. If there was a standard brick producing, say, 12V 1A DC with a standard connector this could be minimised.
