Can I use marine batteries for my car?

Answer by  karm (164)

You're damn right you can use a marine battery in your vehicle. OBVIOUSLY it really is not a great idea to put a big cranking APMS Marine battery and put it in a honda civic, but for the most part it is no problem whatsoever. Don't assume any Marine battery will fit in your vehicle, check first.. just look.

Technically as long as it has the same cranking amps and is 12v you can use it but it may not be the best option.

No, you can not use marine batteries for your car. They have a very different power output that is designed for marine motors. It is not compatible with a car.

When we are thinking about useing a strange battery in our car, firstly we have to make sure that it`s voltage matches our car`s electric system and that it fits into the space where the battery goes! If the battery complies with theses conditions then the answer is more than likely yes!

The Deep Cycle would need to be .4 Factor (40%) larger to have the same Starting power (CCA) as a Auto battery down to the 20% discharge level....1 cubic inch= 2 CCA's, and you need a 700 CCA auto battery, then the Deep Cycle needed is 980 CCA's via Formula

Auto batteries can only discharge 20% of their RH before they are "dead" (10.? volts), and can only do this around 40 times, before replacing....While Marine batteries, can discharge 80% before reaching ("dead") and do it 500+ times before replacing, by using the conversion, the Deep Cycle.......continued

A close simple conversion for auto to deep cycle batteries...RC (reserve capacity) is 25% of the CCA (cold cranking amps)....AH (amp hours) is the RC multiplied by .6 Reverse this formula to find the Deep Cycle battery's CCA....Then use a hammer/sawsall to fit the DC battery in your car....

Yes!, most small boats hve no charging system, so require a long lasting low discharge battery, auto batteries are a short lasting high discharge battery, as long as you can stick a large enouph Deep cycle in your car, you'll be fine, with only minor difference in longer charge rate
