Default Best way to charge batteries?

Can anyone help me out? I just bought a Duratrax Onyx 230 charger and I need to charge my 2600mah 5-cell hump pack receiver battery.

its NIMH.

is it best to charge the battery at low amps for a longer time? like .30 amps for 250min?

or not.

if anyone has a setup for me let me know.

the Onyx is fully customizable and if you know the amps to charge, the time, the peak detection mV/C setting, and the trickle charge mA. let me know please.

If it is the first time charging the pack, then a couple slower charges at first is a good idea. If not, charge at 1C, or roughly 2.5 amps in your case and be done in an hour.

I personally don't like charging small receiver packs at more than 1 amp. The little cells can't take the heat like the Sub-C (which is where this 1C thing came about). Excessive heat will damage the cells and at the very least shorten their lifespan.

In my experience lower is better... If time is a factor you might want to charge right before you go to the track or the night before. If you leave it charged a week.. chances are the NiMh pack will have lost some of its energy. When I used to race gas, I had a spare pack I would charge up at the track just in case..
