I was given three boxes of assorted "dead" batteries today, most of which probably really are pretty dead.

But some may be salvageable, such as cells from some 12V and 18V DeWalt NiCd toolpacks.
A sample pack I opened has fuzz from leaky cells at one end, but the other cluster seems ok. Have to separate them out and see which ones are shorted from dendrites.
Also seen in the bottom of the pic are some SLAs, 12V 7Ah, and they're all very dead, only good for recycling, once I get enough lead to be worth a trip down to trade them for cash. A couple of other smaller sizes, also dead.
There are also a bunch of handheld radio packs, also NiCd.
A few emergency lighting and other packs.
It'll probably be a while before I get around to doing anything with these, given all my other projects. If there's anyone here that's local and wants to trade for junk they have that's unusable to them but might be to me, I'd be open to that, too. I figure if I have time I'd salvage enough cells to series string into a 72V pack, and charge it 1/2 at a time with my 36V NiMH charger. Then try that with any of the controllers that'll take at least 72V, once I repair one. Give it a whirl and see how long it'll actually run a bike.
