I would encourage you to also check your charging system after installing a
new battery.  If your voltage regulator fails in the open position it will
allow the alternator to overcharge the battery.  This causes the battery to
"boil," losing water as it does so, and generate a tremendous amount hydrogen
gas.  Now you have a very explosive condition that doesn't need much of an
ignition source for you to suffer a Hindenberg episode.  A very nasty event
indeed.
Drive safely.
