Okay, I'm a consumer I spent $50 (35 UK Pounds) on a consumer NiCad pack for
my camcorder. Originally it gave me 40 minutes recording time, but now it's
down to 15 minutes and falling fast.

What do I have to do to get back to 40 or so minutes? Or do I just throw
away $50? To me that's a lot of money and I'd like to get proper use.

If you can be fairly specific (remeber I'm a peasant consumer, not an
electrical engineer), I would be grateful. I could manage with a circuit
diagram and a list of parts or even a Radio Shack part no.

Sorry to go on, but my system says I must post more than I include ;-(
