The brown stuff on the metal is referred to as rust/corrosion.
Clean it up, focus your picture on the item instead of the tape measure.

When somebody IDs the item maybe say at least a "Thank You" and then mark it solved.

It may be a battery for my cordless Makita drill. Is it 18V?

It's old enough to look like an unidentifiable rusty hunk of metal.

Bart, on items like that run it through electrolysis first so you can see the actual metal.
