Marine battery difference

What is the difference between a marine battery and a regular battery .(besides the Posts)?

Dalex · Jun 26, 2014

Marine battery is designed to be constantly run dead and then recharged so the metal in the plates is a different alloy . Think Trolling motor usage.

there are two types of marine batterys. one is a marine cranking battery and the other is a deep cycle marine battery. deep cycle has finer plates to supply a low power drain over a long period of time. a marine cranking battery has heavy plates to supply high initial amperage for starting an engine. the batterys are heavier constructed to handle the shock from pounding thru waves.

Hello,

Marine battery output is rated as C.A. and are rated @ 32*F. While the automotive battery is rated C.C.A. @ 0* F. If both batteries marine and automotive, have the same amp rating, the automotive is the one with more power,

The batteries sold at Wally World labeled RV/Marine I consider Quasi Deep Cycle Batteries.

They can deliver a high enough short term burst of current to start a fairly huge outboard motor PLUS have some deep cycle capacity to operate a low current but long term draw like a boats 12 VDC trolling motor.

A true Deep Cycle battery like used on golf carts are designed more for a slow but very deep low current discharge. Yes, they could still start a car, but are designed (plate design) for less current longer term deeper discharge.

A automotive Starting Battery is designed to deliver a sudden short term but very high current to start the engine. Yes they could still "operate" a golf cart but not as well as a deep cycle battery does.

If you have to start a hefty sized outboard but still want to use the trolling motor, an RV/Marine can be fine.........If you want a car to start well a regular auto battery is fine.........If you do extended dry camping in an RV then a true deep cycle golf cart type battery is good.

I'm thinking of my trolling motor usage, and my goal is to NEVER run it dead- that would mean I'm stuck in the middle of the lake and rowing for shore. I would think deep cycle batteries for trolling motor usage would always be recharged from something more than a full discharged condition. No matter how much or how little I use my motor, I'm darn sure going to charge the battery up again before the next trip.

Trolling motor batteries do need to be charged after each use. They have a very short life also. 2 year warranty is the best I have seen and after 2 years it is usually gone. As far as starting a big engine from a trolling motor my Mercury manual says not to do it because there are not enough amps to turn the engine over. And i only have a 115 HP engine.

Thanks for replies. Was wondering which would be better on a electric fence.

John T · Jun 26, 2014

For an electric fence the cheaper Wally World Semi Deep Cycle RV/Marine Battery would work okay. That load is very small in amperage but for a long time duration. Id prefer that over a regular automotive battery as you don't need the ability to produce several hundred amps like may be needed to start a car.

I use a Wally World deep cycle on my sheep fence. Gets charged once every couple weeks. It's gone 3 weeks and still shocked the crap out of me.

It's the other way around.
