Q: With the recent M4 I just got the battery is dead and must be recharged. This is an Intellect 9.6v 3600mAh NiMH Crane Stock, it has taken so mini. The charger I have is a IntelliPeak A: Hmmm ... Are you sure the battery connector is wired for polarity? If it backwards (rare but not unknown), then it could be the source of the problem.
