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 ;-( Mike Quinn. Abekas Video Systems Ltd.
