How to use charger?

[James]

I have a charger i bought to charge 12 GP3700 batteryies, and i dont know what current % thing to put it on. I can put it on 10-20-30-40-50-60-70-80-90

Hey James - I would say a safe bet would be about 6 amps - maybe 6.5 amps if you wish - should be ok at that rate.... Good Luck

6.0 amps i thought that is more for NiCd? my 3300's charge at three amps beacuse they say that NiMh's max amp charge is 3? is it safe to go further than 3?

Yea it is safe to charge at more than 3 amps for the nimh's - most people charge double the capacity of the battery - eg. 3300 battery - 3300+3300=6600 - break that down to amps it would be 6.6 safe charging - i go with 6 amps - that has worked for me in he past -

i charge all my nimh batteries at 6 amps. it seems to be the best that i have found

From what I've read in the past, charging at a high (~2C) rate increases the voltage at high current draws but gives up some runtime, while charging at a slower rate (~0.5C) reduces the votage under high current draw, but increases runtime. Someone please correct me if I'm mistaken, but this seems to hold true from personal experience. I usually compromise though; I charge a 3300mAh battery at 3-3.5A (~1C).

That's what I've always been told. I've always charged my NiMh's at 4.0A on my Super Brain 959 for my speed runs and 3-3.5A for normal use.

i have a dynamite vision peak plus charger and its been acting up. i dunt know if this is normal but should the voltage numbers go up and down. they dunt charge my batts all the way as well.
