Re: Seems like cordless batteies always dead when needed.
Interesting. Does the battery have contacts for a balance connector, to use with the RC charger?
With just 2 contacts to the charger, it can't monitor individual cell voltages, and I would be very leery of charging it that way. That's dangerous.
But of you can connect the balance leads, so the charger can measure each cell, you *should* be able to charge it completely, and safely.
I'm guessing it's 3 cells? My chargers allow setting the type of lithium cell (LiPo, Li-Ion, etc), each of which have different charge-termination voltages. I guess I'd hope that you can charge this properly. An RC charger may be more capable/versatile than the included charger, if you're willing to deal with the inconvenience. And the responsibility to set the charger correctly each time, of course; it's not as friendly as just dropping the battery on its specially-made charger.
