Marine Battery

[macojoe]

I also run auto batterys!! Marine comes with crap warr, and they never seem to last more then 2 seasons??

Auto comes with up to 8 years depending what you buy.

as for why they use 2 batterys, one for electronics, and one for start and run.
Most are on a switching system so the power can be on one or both batterys or both off.

This way at rest on the water you can run all your stuff and still have a battery to get home with.
