Howdy folks. I got an external battery pack in good cosmetic condition for my Zenith supersPORT. The inside looks clean but after 24 hours it was only up to 1.4V or so and didn't seem to be going past there. Based on the size and shape of what's inside, I think these are just standard 1.2V nicad cells, same kind you find for rebuilding 12V tool battery packs on FleaBay. Anybody have any experience rebuilding one of these (or similar) successfully? Any good links or howtos on how to go about it? I briefly searched the forum but didn't see much on the topic. My gut says I can just replace the cells and solder them together in serial but I don't want to do the wrong thing and burn down my workshop or worse, damage my Zenith :mrgreen:
