Hi,

I think it is different kind of batteries here. Batteries for auto are
mostly gel cell type. They are maintenance free and the electricity doesn't
discharge fast during hot weather. Most RV/Marine batteries are wet cells
type with water inside. If under constant hot weather, the water inside
each cell will evaporate faster and this means the electricity will be
discharged faster. This is all I know why you don't remove the battery from
your auto which is only a few inches from the hot engine. And also the
front of the automobile has a big grill but not a boat. For the boat, the
battery is always hide under the deck of a seat and has limited ventilation.

Why? Do you remove your battery from your car or truck and it's just a few
inches away from a 200* engine.

Hi,

I would like to remove the battery of our new 18' Sea Ray and store it
inside the house for awhile. The boat is now store inside the garage
and
only has 15 hours in it. I am in Las Vegas and I know the temperature
of
the garage shoots up to at least 130 to 140 during noon time. Its a wet
cell battery, I am worry that the battery is draining itself due to hot
and
stuffy condition. The problem is I have never removed a car/marine
battery
before and don't know the steps. I don't want to get shocked or damage
the
engine of the boat. All I know is when I helped to jump start a dead
battery of a car one time, there were sparks on the booster cable clamps
when they touched each other. Would someome tell me the steps please.
Also
for putting the battery back inside the boat.

Thanks
David
