If I have a normal 1.5v AA bater and I use a multi meter on it and read 1.2v is that how much juice is left and if so, around when do batteries stop working
if it's a NI-MH / Ni-cd battery then 1.2v is correct. Mostly Alkaline batteries are 1.5v More infor and links here http://www.yourzagi.com/batterybasics.htm
well i was using 1.2 as an example, but a normal battery is 1.5 is a used batter gonna read less on the meter?
