Default Car or Marine Battery

The web is so full of misinformation on this I have to ask the experts. I am comparing a Marine STARTING battery to a car battery. If I both are sealed lead acid and havethe same the correct cold cranking amps , what is the difference other than color? I am NOT talking about deep cycle batteries. I know that difference.

Thanks

Marine is suppose to be more shock resistant.

I could be wrong but I was under the impression that automobile batteries were rated for much colder temps than marine batteries

Marine are better cause they say marine on them




In all seriousness I have been using walmart auto starting batts and walmart deep cycle for 25 yrs or more. No problems, easy return if they go bad.

I've used both in my boat and never had a problem with any of them.

That's for cranking amps. Batteries can be specified for either or both. MCA vs CCA (marine cranking amps vs cold cranking amps). MCA is rated at 32F and CCA is 0F

I think the biggest thing you'd see as a difference is the terminals. Few marine batteries have side posts and few, if any, auto have studs.

I've heard the thing about the marine ones being built different to take the vibration but I don't think that's valid after driving on all kinds of roads with potholes!

Thanks

I suspect they may be more shock resistant. The colder temperature for car batteries is more stringent than the boat batteries so I don't think have to worry about that???My Contendercame with Industrial AGM batteries By Deka - PennIndustries - real heavy 1000 CCAs. Gonna put n somehting I can get local - either Interstate or EverStart? the wallyworld brand - have had good luck with both

I've been planning on replacing my three lead acid Interstate Marine "dual purpose" batteries with Lifeline AGM but $300 vs $900 total is hard to stomach.

Gotta' love their warranty program, "Yeah, it's toast. Grab a replacement and bring it to my register, I'll get started on the replacement."

Marine batteries have a label on them that increases their wallet draining capacity.

I always thought there was something different when it said Marine on it. Crown battery is close to where I live and I really like their batteries. The guy told me the difference is the label and the price.... Then he told if I told anyone he would have to kill me so please keep it to yourself.

As far as batteries go when I was at Crown Battery he asked me if I would take a blem battery, I had never heard of a blem battery but it had a label that was crooked and it had a little piece of plastic broken off of one of the corners. The price for a perfect battery was $159 and the price for the blem battery was $99. Who cares if the label is crooked or there's a little piece of plastic broken off!

Made me laugh, but I’d go with a marine battery for a marine application.

I have several customers who make batteries. The physical differences are in how the internal parts are supported to withstand shock and vibration; the thickness of the plates and the interconnections. A 100 AH marine battery will be significantly heavier than a 100 AH automotive battery.

Russ, are you saying you bought direct from the factory? In Fremont?

That is what I read and makes sense - but I am thinking my car does more and harder bumps and jostling than the stern of my boat ever even could. Maybe batteries in a light CC in the console could get a good slam though...........

And this, my friends, is the internet in a nutshell.

When I go back home I always stop in at Crown and get some blemish batteries. The marina here has actually started selling crown now too. All my family goes there to get batteries when needed.

If Russ died today, Crown Batteries will get the blame , cause Russ gave out corporate secrets.

watch your back Russ !
