Marine battery in my truck??

if it's a deep cycle battery, they are not really designed to have the
large momentary draw of a starter, but they will work.  If it's a marine
starting battery, (like for an outboard or sterndrive boat) then there's
really no difference.

It will blow up eventually.  They have to be deep cycled .  They get a
voltage step if you dont  run them down .  I loaned a 1000 amp deep cycle
battery to somebody. Until they were susposed to get a new one.  They ran it
in their truck until it blew up.  About 8 months. It says right on the
battery not for continuous use.

Theyre designed to be continuously discharged , with heavy thicker plates.
Not continuously charged.  As in cant disapate heat.

I suspect "blow up" means something different to N4U than it does for the
rest of us.

umm , No,  hear a boom, then the batteries split open.

Depends on the battery.  Some are rated for both cranking and deep cycling.
I run AGM (lot more money) marine for both cranking and continuous discharge
applications on my bass boat.  They are about 2 years old now and still
about 90% capacity.  (I can run the 109# TM at 75%+ thrust all day long and
still have plenty left over.)  The cranking battery is also the anchor
battery for my 36V circuit so it really sees some abuse.

All marine batteries whether cranking or deep cycle should be built a little
more robustly as they take a lot more shaking and pounding.  Not always true
of cheap box store batteries no matter what it says on the case.

 

There is a RV battery you can get that is a comibination starting and
deep cycle.
