marine battery? yes or no

[2000fordstanggt]

well its time for me to get a new battery and I was thinking of getting a duralast "marine starting battery" its got either 750 or 800 ca.
I'm pretty sure its deep cycle (itd have to be, right?) and I know the differences between the two fwiw.

so its basically another "can I use my yellowtop for my starting battery" thread. it has the aux terminals which is nice and is about $70 w/ core.

opinions please, thanks!

You "could" use one, but it's service life might suffer from the repeted abuse of high current starts. If it were me, I'd stick to a regular one.

how much would it really suffer though? or is there no way of telling that before hand?

i would like to be able to play for radio for awhile and not worry about killing the battery, i was under the impression once you "kill, or drain" a new/good battery its never the same after.

if i do drain the battery isnt a deep cycle built to be drained and recharged over and over again?

They are made differently. Heavier plates to withstand the pounding they take on rough water runs. They are made heavier everywhere. And their ability to retain heat also increases, which will shorten their life under the hood of a car where temps are far higher than they typically see on a boat.

Expect shorter life, and they will not produce near the amp flow because the plates are thicker and there are fewer of them to allow high electron migration. So current flow will drop significantly. You may or may not need that current flow of course.

the spiral cell batteries are the best thing going, but they are pricey. Various suppliers are making them. but they aren't 50 bucks.

I bought mine from the Ford dealer, price was good and you know it will fit.
