I have 2 NiMH batteries for my FireBird XL (900mah) and and eight and seven cell NiMH for my PicoStick. I haven't flown either in months. Now none of the batteries hold a charge for more than a few seconds. I'm using a Dymond Peak Multi Charger (and have ever since I got the Pico Stick)

Please help!

Thanks

What are your voltages?
You could have a bad cell or an open circuit.

Might try a slow C/10 charge on the cells - they lost all their charge sitting, and may need to be "reformed" with a slow charge.

My guess is the same as your last reply. They are NiMH and have gone to dead. Slow charge them and see if they will reform.

Thanks for the help. My Firebird batteries are good as ever after I got a charger that could slow charge them. The Pico Stick batteries are also good to go but I found part of the problem was the motor is on its last legs.

Thanks again
