Hi - was wondering if anyone has any suggestions on a battery cycler/charger.

I have been flying my NexStar a few months, recently soloed and am noticing my niCad RX battery really losing a charge quickly. In fact, even after 1 10 minute flight, I check the battery and it's just barely "still in the green" on my hobbico meter.

I recently bought 2 backup batteries to increase my flying time ( more than 1 flight) at the field per day.

I'm wondering a) is this normal for a battery to only hold a charge for such a short time given the age of the battery b) would putting it on a discharger/charger improve this or c) is this battery just hosed?

Does anyone have any recommendations on a cycler that wouldn't cost > $50.

Thx
