Marine vs Standard Automotive Battery
Marine vs Standard Automotive Battery
(OP)
I'm looking at Marine/RV batteries to replace the standard battery in my car. The Marine/RV battery is a deep cycle type, and is actually more economical than the standard battery. The particular one I am looking at is rated at 1000 cranking amps (CCA 800), while the standard battery is only 763 cranking amps (CCA 610). Are there any obvious concerns I should have with the higher amperage?
On another note, I have also been seeing "high performance" 16V automotive batteries recently, and am just curious as to the pros and cons if anyone can answer that.

RE: Marine vs Standard Automotive Battery
I've never seen a 16V automotive battery, don't know how that would work since the voltage regulator is going to charge it to only ~14 volts.

Do you know the charging voltage of your vehicle??

Something else to keep in mind - many marine deep cycle batteries are wet cells, and overcharging them can lead to the water evaporating (actually a chem reaction, but whatever) slowly over time. It's not a problem as long as you check it every so often and top them off with distilled water. Not sure if this would be a problem or not in an automotive application.

I'd be tempted by a marine battery with greater cca than the automotive one, but if the Ah capacity is a lot less there could be unintended consequences.
I'm struggling to think what they might be, admittedly, if you don't intend leaving the lights on all night deliberately.

TOday, when a spare tire is left out of cars to reduce weight so federal gas mileage ratings go up, and new car tires are inflated with nitrogen so the inflated tire weighs less than if filled with air, no auto builder is going to use a heavy battery deliberately.
You may be comfortable doing that - it's like leaving a box of tools in the truck. They are heavy, and will reduce mileage slightly.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Interestingly, the claim is that despite a relatively small kinetic size delta, the permeation is 3x to 4x higher

Now motorcycle tires seem to be much more porous. I have to top them up at least once a month and check them weekly. I chalk that up to their light weight and flexible construction. Reminds me, I have to do so before heading out in the morning.
