Battery Information
This site information will help your question:
Battery Information
For charge rates on your NiCd use a 2 amp or under charge.
For your NiMH battery do as "T" says go by the number and use a charge rate close to it.

I've used 2 amps on all batteries and never had a problem.I also have 4 amp LiPo's which I charge @ 0.8 amp which in my mind is a safe charging power for such volatile batteries.

man take it from me all those chargers are a waste of time they take too long,i have tried loads of chargers and the one i use now is a peek detecting unit from traxxas,it is a quick charger that is cappable of fully charging a 4500mah battery pack in 30mins,and has a flashing light on it to tell you it is full......
it is excellent,and cheap,comes stock with most revos and t-maxas....best charger i have ever had.

A battery is only as good as its charge. Charging too fast or incorrectly for the type of battery you have can damage the cells and lessen it's life. In the end, there is only so fast you can charge any battery.

no these charge correctly btb,like i say a peek detecting charger,it keeps charging untill it is full.
i have been charging my 1/5th batterys now for a long time and my batterys have very good holding power,i could easily get two days running power from a single charge,no joking!!
it is a great charger.

ok T...i see your saying your charging at 2.2 and 3.6 amp...but like i said the charger only does 1,2,0r4 amps...wots the difference with ampage...not gonna use the 3700nhmi yet thats really a backup just incase the others were bobbins as they came with the cars...but to be fair there not to bad just want to get the best possible life/performance out of them...i don't mind the charger either it also seems to work ok..thanks guys
It's possible to charge a battery too fast and cause it to overheat and vent, thus reducing it's capacity in the long run. Hence I use a decent charger which keeps track of voltage and temp during the charge process, and also why I charge a pack at a low'ish amperage setting.
