[SATLUG] How to remove a swelled APC battery?

Massive overcharge! I have heard of refrigerating the UPS unit to reduce the swell. Puncturing the battery to release the acid and render the unit trash ... unless you are REALLY, REALLY careful.

This morning I came in after the wind storm to find 2 of our UPSs
powered down and unable to turn on again. One of them, an APC
BackupPro 1400, I did manage to wiggle the battery out. The 2nd UPS, a
BP 1400, has a really swelled battery. I can't even wiggle it from the
case. Is this UPS toast because the battery will not come out? What
about puncturing the outer shell with a screwdriver and draining some
fluid. Would that help?
