Thought it might be a battery pack at first so I wasn’t going to touch it but it appears to be plastic.

Possibly broken at the top? Unsure.

Looks like a PJ996 lantern battery whose top cover broke off. It's probably carbon-zinc, in which case you can recover a decently big graphite rod from each cell.

I'd warn against opening the cells if you don't know how old it is. Modern ones are safe, older ones might contain heavy metals.
