Found this in the trash. 6 cells in paper sleeves, spot welded. Heavy as hell. There's some black foam/compound on top. Is this from an old vacuum or a power tool? Ni-Cd or Ni-MH? Post ideas. I'm on Linux Mint btw.

Actually, I found TWO of these packs, and each has 8 cells (16 cells total). They are identical.

Presumably NiCd. It is, in fact, trash.

since you said they're heavy it pretty much is narrowed down to nimh, nicd, or lead acid for commercially produced chemistries. the lack of venting and spot welded construction makes it unlikely to be lead acid. if someone made it themselves it could be just about anything.

bring them to a recycling center just to be on the safe side. cadmium is hella bad for the environment and is otherwise a fairly useful commodity that deserves to be recycled. its ill advised to use a battery when you don't know the exact chemistry and nicd batteries are trash in almost every metric compared to most other available chemistries.

Damn, I can't count. You're right, it's 8. Thanks for the correction and for being the only serious person here.

don't bump this thread will be around for months unfortunately.

Nicd can tolerate complete discharge.
They also tolerate being left outside in Montana winters.


You might be able to use them as individual cells.

I have a drill battery with a similar setup.
