Default Just wondering, Ni-cd charger used on Ni-mh

@dreader2.cybercity.dk:

Mine are 2 and 2.5 AH, but they actually take less time to charge on the
Ni-MH setting than on the normal setting.



Yes. The NiMH setting charges at a higher current. Ni-Cd chargers will
charge them, but at the slower rate...which isn't a bad thing at all.


You have to be carefull though. NiCD is usually charged either at C/10 rate
of at high current, where a drop in voltage is used to detect the end of the
charging cycle.

The C/10 charge with NiCD cannot overcharge them.

However, NiMH batteries show a much smaller voltage drop when full, which
might not be detected by a fast NiCD charger. Also, overcharging NiMH at
C/10 will certainly damage them. So be careful!
