Can NiMH batteries be recharged using a normal AA charger?

Wondering if I need to buy a NiMH charger for NiMH batteries or a
normal AA charger will work with the NiMH batteries. Can anyone tell me
if this is possible?

Thanks in advance!

What is a "NORMAL" AA charger???
Absent any useful information...it's prudent to charge batteries with
the charger designed to charge them.

Not according to
http://www.starbatteries.com/chargerfaqs1.html#Can I use my older NiCD

"Can I use my older NiCD battery charger to charge my NiMH batteries?
No, you can use a newer NiMH charger to charge your old NiCD batteries but
you should not try to charge NiMH batteries with a NiCD charger. Here's why:
NiMH and NiCD batteries are chemically very similar and when both are fully
charged the battery voltage will start to drop. The NiMH voltage drop is
much more subtle and more difficult to detect. NiMH chargers usually have an
overtemperature sensor and shutoff to prevent overcharge as well as a more
sensitive voltage drop detector where NiCD chargers usually only use the
voltage drop to determine when to stop charging. If you charge NiMH
batteries in a NiCD charger it will probably miss the voltage drop and keep
right on charging causing the batteries to overheat. Overcharge and
overheating NiMH batteries can damage them internally and reduce battery
life."

You'll also find a new charger will be better geared to the higher
capacities usual in NiMH.
