Brent,
THE chlorine gas forms from the acid mixing with seawater.

Subject: RE: [PSUBS-MAILIST] Optima Battery Data
Thanks for the information Alec. I
was in a battery store today that sells a lot of Optima batteries, and they
donated a used red top battery to me to do some destructive testing on.
They do have two small vents on the upper corners. But they are very different
of course then your standard lead acid batteries removable caps. The guy said
that if one of those vents pops out that the battery is dead.
Also if the charge gets
to low then they will stay dead and they should have special computer changing units
that can charge them with a constant voltage. He also said that I don't
need to space or ventilate them for heat issues. The guy didn't know all that I
wanted to know about them, so I'll have to keep digging.
Is chlorine gas
produced from the poles on a regular lead acid battery, or from the interior if
saltwater gets inside?
There are three power
sizes of deep cycle Blue Top Optima's. But two of them are the same
physical size.
34M and D34M model
is 10" L x 6 7/8"
W x 7 13/16" H and they are 38.4 lbs and
43.5 lbs respectivly.
D31M model
is 12 13/16" L
x 6.5" W x 9 3/8" H and the
weight is 59.8 lbs.
