Dead CMOS Battery - NEC Powermate portable

Same stuff that combines in the atmosphere (clouds) to form rain made of
sulfuric acid - acid rain.

My previous post on the exploding lithium on a NiCD port I failed to mention
what it did to the traces and open chip legs - corroded the crap out of them
and it did indeed stink the hous eup but I always leave my shop window open
a crack since I have a habit of using a lot of volatile chemicals for
cleaning and such.
