NiMh Questions
 

O.k, need a few things answered with NiMH batteries as can't remember.
1) If I fully charge a battery and then don'tuse it for say 7+ days or whatever, can I run it in a car without recharging? (i know it won't have full capacity)
2) Is it recommend to discharge the battery before charging?

Thanks in advance

1) Yes
2) No

If your charger has a re-peak feature, you can use that to re-peak before running if batts been sitting since its last charge.

There is no need to disch before charging, just don't be surprised if batt takes way less than its rated capacity since you're starting with partial charge. Best way is to disch by running them.
