How hard is it to charge a NiMH battery?
Charging NiMH cells is a little more difficult than their NiCd predecessors because the voltage peak and subsequent fall that was used to detect full charge is very much smaller on NiMH batteries and cells.
Why does my battery get warm when charging?

Can you use NiMH and NiCd Charger together?
Don’t intermix the chargers. A NiMH charger can also charge NiCd; a NiCd charger would overcharge NiMH. As NiMH cells are more sensitive to the way they are charge when compared to other forms of rechargeable battery, care needs to be taken to adopt the correct NiMH charger and also to use it properly.
How long does it take you to charge a 2100 mAh battery?
My “rapid charger” charges my 2100 mah batteries in about an hour, and when they come out of the charger they’re almost too hot to hold without changing hands. I’ve wondered about that myself, but I’ve had this set for a little over a month, and about 5 or 10 charges, and they still seem to be working fine.
