1.13. Do NOT use wet lead-acid batteries around salt water. If salt
water is mixed with the battery's electrolyte, deadly chlorine gas is
produced. Only use sealed AGM (Ca/Ca) or Gel Cell (Ca/Ca) VRLA
batteries around salt water.

Good advice I think.



The advice is Ca/Ca, allright. AGM and Gellcell batteries ARE lead acid
batteries, just like wetcells.

Wetcells PROPERLY SECURED INTO THE BATTERY BOX are just as safe as the
other batteries for thousands more because they have gas vent caps on
them that seal out the seawater and seal in the electrolyte in case you
pitch pole the boat doing something stupid or a rogue wave hits.

Most batteries, regardless of technology, are just sitting in the
battery hole waiting to come out upside down to kill someone or start a
fire hanging on their poorly installed battery cables.

A recent sinking at an unnamed marina of a 40' sloop who's bilge pump
clogged, causing the level of the water OUTSIDE the hull to be higher
than the lip of the defective marine head INSIDE the hull....valves left
open so it could flood hard and sink....prove there is really no problem
with wetcell batteries in boats.

The battery compartment of this sloop went underwater for about a week,
the boat simply laying low in the water before someone noticed it and
did something for her. The DC power in both the two AGM house batteries
and the wetcell regular car starting battery ate the terminals off BOTH
types of batteries conducting through the seawater between the posts.
The bolts finally electrolyzed away and the cables were simply left
hanging underwater in the battery box under the cabin sole....it was
that long.

All 3 batteries survived the sinking! The AGMs had plenty of power left
once you touched the cables to where the posts USED to be, indicating
they were not sea water flooded inside their crazy battery cell tubes.
Likewise, the Walmart sourced car starting battery used to crank the
Yanmar on the cheap also still had around 12.6 volts on its rotted away
lead posts and seawater did NOT make it past the electrolyte traps in
the pressed in multiple hole cell plugs that fit flush with the top of
the plastic case.

They were all fine....wetcells and all.....

Obviously this was NOT the case for the fake interior panels made of
expensive wood-veneered plywood, which all came apart as the sea water
soaked up the cardboard base.....and seats.....and everything made of
metal was simply eaten...pots/pans/utensils/even the beer cans floating
around inside the ice box....9c;

What a terrible waste of good beer.....
