Electrocution is but one way to die from too many columbs.
Internal burning is a big one.  Most people die, not from immediate
cardiac arrest, but rather from kidney/spleen/liver failure as
they try to remove the cooked you parts from your bloodstream,
and clog up. (First responder treatment is multiple saline inputs
to flush you out, and keep flushing you. This via a friend who was
"lit" and lived.)

The instantaneous short circuit current available from a CO-grade
battery string is nothing short of frightening. It will easily
turn a 18" crescent wrench bright orange and start spitting the
molten metal around within few seconds.

I'm surprised you're still around after a sub battery accident.
They're a grade up from most CO's in available current, I'd bet.
