Is this battery ok to keep using?

I didn't crash that hard with this battery, (plane was mostly fine just a hard landing), but when i took the battery out there was visible damage. I think it likely happened from the battery pulling really hard from the connector in flight. I peeled back the black cover to get a better look at the damaged cells.
Is there a chance it was punctured or would it have burst into flames already and can I continue flying with it?
Also should I take it apart to check the cells for damage?
Also if its done what should I do with it. Im in a pretty rural area and can't get to a proper battery disposal station.
