I inherited a charger and 4 MI-MH AA batteries that I use in my camera. When I got done charging them they only showed 1.42V. Thought They were shot then I looked at the battery and they said they were 1.2V. Why is a regular AA battery 1.5V and these NI-MH AA batteries only 1.2V and why do they work in the other batteries place? Heck I toss my regular batteries when they get that low except where I use them in my garage clocks.
For comparison, think lead/acid at 2.0 volts per cell or LiPo/LiFe at 3.7.
You really need FIVE NiMh batteries if you need 6 volts, but most devices will work with 4.8.
The difference is that a carbon-zinc or alkaline battery IS nearly exhausted at 1.4, but these NiMh/NiCad ones have LOTS of charge left at that level.
