[QUOTE="WayneF, post: 368076, member: 12496"] If you use rechargeable batteries, the meter could not be useful anyway. Such battery meters (for AA and AAA batteries) are designed for alkaline batteries, which have a voltage that gradually drops, 1.5V to about 1V, and the little meters are just volt meters which show that progress. But rechageable NiMH have a more constant voltage over their life, around 1.25 volts or so. They really don't drop much. Then when expended, they just die suddenly and quit. So the meter would just show maybe 2/3 charge initially (even though it is fully charged), and it stays there until it quits. Not much point of that. :) The SB-700 does have a "low battery" indicator. It should be able to show a dead battery I suppose. [/QUOTE]
