Battery explosion?

Has anyone heard or experienced this?

On changing the battery in our plane the other day, the A&P said, "You had
a
battery explosion." On looking closely, I could see that the box was
bowed
out and rounded as if someone had tried to inflate it with air. I'd
noticed that it wasn't exactly square and the cover didn't fit very well
but
thought it was just poor workmanship.

He said it probably happened during starting from hydrogen build up that
the
propwash hadn't had a chance to blow away yet and the pilot thought it was
a
backfire. No harm done except we'll need a new box because of corrosion.
It could have happened years ago.

Funny that this should come up. I had my first experience with battery
explosions, this past Friday.

An associate was charging a tractor battery with a large automotive charger
at a high rate, and asked me to come over to see if I thought it was
charging well. I went to see, and it was bubbling away to beat the band.
He then reached down to check the tightness of the charger on the terminal.
All this happened so fast, and I was not able to prevent what you all know
happen next. It sparked, and let out a very surprisingly loud, BAM!!!. A
little acid splashed about, but fortunately, I wear glasses, so no great
harm was done, other than seriously ringing eardrums.

If that large of an explosion went off in a battery box, it is lucky that it
didn't completely split it open.

Sh*t. More hearing shot to hell, that I don't have to give!
