Is there any kind of FAQ on how to test how much juice is left in say a AA battery by using a multimeter?

Not quite. Most multimeters do not apply any load at all whatsoever (or a load that's far too small to affect the battery much) upon the battery being tested; as a result, a multimeter will only show you the initial open-cell voltage (for AA NiMH rechargeables, this amounts to about 1.4V) regardless of the charge level or battery condition. The only way to correctly check the voltage of a battery is if you use a battery tester - one which also applies a typical amperage load upon the cell as it's being tested (a multimeter applies an amperage load that's far too low to be meaningful).Soldier Prime said:you need to set your multimeter to 2DCV and it will give you the right reading, just make sure you hold the red and black on the right ends lol
