Can a NiMH battery be overcharged?
3. Don't overcharge, don't under (trickle) charge Nimh batteries should never be overcharged, the maximum capacity for any NiMH battery is 120% (which is what your NiMH charger SHOULD charge your NiMH batteries to before auto shut off, @Rudd looking at you)
Can a NiMH battery be slow charged?
Slow charging NiMH batteries: NiMH battery slow charging is not to be recommended. Using charge rates of between 0.1 and 0.25C do not provide the indicators needed to detect the end of charge. With voltage changes of only about 5mV at full charge rates, the smaller changes arising for a slow charge are virtually impossible to detect.
How do you charge a NiMH battery?
Slow charge your NiMH battery the night before using on 1a current, charge until charger declares the battery full, then leave it to rest overnight....when you wake you should take the battery and charge it again, this time on 4a, for a brief period (around 20 minutes or until the battery gets hot)
