Battery prob's

[losidan]

Awright chaps...wonder if anyone can tell me what is going on with my cells.....

I've got 4 packs of 3300's and i have had them stored for a few months. Before I did. Rightly or wrongly (cos i wasnt sure) i discharged them and then put them on a an orion discharge board.

I have got them out with the intention cycling them a few times but now the packs when charging get very hot and start to make a low sort of pulsing sound after a while of charging.

I charged them at 5 amps and this is happening and also charging at 4 amps. The packs are a few years old now cos I bought them 2nd hand when i got them.

Can you tell me what is happening and importantly ....are they screwed? I charged a packs tonight and it started happening 3000 mah according to the charger...I took it off charge straight away. I ran it in the car and it seemed fine....

Thanks ahead chaps
