I pulled the battery. I will replace it later. Going to do clean system install also.

Seems to me the solution is to run leads to an external pack that mounts behind the unit. That way, if it leaks/explodes, it doesn't do so all over the internals. Bonus would be to have a little sealed plastic case it all goes in, so that when it destructs, the carnage is still contained.

It'd be neat if someone built such a kit that had spring clips or a fake battery on one end, a few feet of wire, and a plastic case with a CR2032 holder on the other end, possibly with a magnet or adhesive patch to affix to the back of the unit.

This also works. You could also get a normal Mac PRAM battery holder, solder wires to it, the use a *CR*14250, getting the same safety benefits as a CR2032, but in a higher capacity battery.
