I am not a battery or flashlight guy, so be gentle...
1. My MagicShine cable seems to have a problem near the cable. Can I get a new plug, cut the cable (it's longer than I need anyway) and put the new plug in? If i can, where can I get a plug? Is it any sort of "standard" thing? I can solder, if that helps.
2. I have four Magicshine batteries (don't ask...) that I've mixed up. Can I use a volt meter to figure out which ones are still good, and how good they are, or do I need to hook them up and see how long it takes to kill them?
