Based on that, I ditch em at least all but the top two voltages you listed. Besides being 15 yrs old they may be holding memory, being nicad. If anything besides being shot, it sounds like that. Burst of energy and then nothing. Being theyre that old I wouldnt mess with them. Some cheapo packs would be better. Not saying go cheap, but anything would be better. You could see if radioshack still is selling the GP3300's for 25$ a pack, that was a real good deal, check their site. If it doesnt say gp3300 on the cells though dont buy them. I got lied to by my local radioshack. But they had them online.
