Can NiMH batteries be recharged using a normal AA charger?

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

Thanks in advance!

 

Buy a NiMH charger.

 

Nice troll.

Just in case you're serious... You need an NiMh charger...and also to read
the package your batteries came in.

 

well actually you don't .. but only if .. you are not in a hurry
and you don't care about possible battery damage ..

 

The answer to your question is definitely yes. However, my son and his
friends have replaced the 'permanent' NiCD's in an electric razor with NiMH
and they seem to be ok using the original charge method. Probably takes
longer to charge.

There is no such thing as a "normal AA charger". Chargers are
specific to battery technologies -- nickel cadmium, nickel metal
hydride (those two can often share a charger, at least if it's
designed for that), lithium ion, rechargeable alkaline, lead acid,
gell cel, whatever.

If your charger doesn't say it's for NiMH batteries, it most likely
isn't.

 

Most "NORMAL" AA chargers were for rechargeable NiCad's. They typically
supply about 10% of the batteries current or less into a NiCad 1.2v at a
constant current and take approx 12-14 hours per charge. They work perfectly
fine for Nimh, although the higher the current rating of the Nimh the longer
it takes to charge. Read the charging requirements of any Nimh. The newer
Nimh chargers are made to pump much larger currents into a Nimh which heats
up the battery, but will charge them faster, a decent charger monitors the
temp and shuts down the current. Heating up a battery WILL shorten its life.
So as a matter of fact a slow charger will lengthen the life of a Nimh
battery. A Lithium Ion battery needs a constant Voltage charger. They can
NOT be charged on a "Normal AA" charger.

 

In an emergency, and if you're careful, yes. But because the normal AA
chargers (meaning NiCd typically) aren't designed for the charge
characteristics of a NiMh cell, you may encounter situations where the
cell overheats, catches on fire, etc. You can manage the charge cycle
yourself - have to get the cell charge tech. details, the charger
current & operation details, etc. - and calculate how long you can keep
a cell in the charger safely, but it's much better to buy either a cheap
NiMh charger (see www.fatwallet.com/c/18/ for these) or upgrade to the
world's fastest - 15 minute Rayovac AA NiMh charger at Walmart stores.

 

Two words for you:

Powerex.

 

IMHO that is very unlikely as most AA chargers I know of are using charge
currents which are barely higher than the trickle charge current for NiCd's
or NiMH's ..
