How to charge a 8.4v rechargable square batt
 

I need to charge a small 8.4v square batt 170mah nimh. I will use a Hyperion duo3 charger to charge it. What shld I set the charger on?

Set it to Nimh and charge up to 1C.

It will auto cut off?

You could charge it on 0.1amps, The lower the Amps going in the fuller charge it'll take.

Yes it can't do 1amp the temp went up to 50degree. I set to auto it's charging at 0.25amp now I use a fan to cool it up.

Btw the charger only has 100 or 200mah which is better?

Fully charge n managed to charge at 66mah into it.
