Marine Batteries

A little more info. You say you use a max of 10ah per night (lighting?) - do you drive the vehicle each day and charge the battery or do you stay in the one place for several nights?
Cheers

Bill,

I am going out today to buy a marine battery for the aux battery in my GU. I actually use the same battery form both main and aux. I get between 3.5 to 4 years out of them. Cost for the battery I use is about $180.00.

I use Delkor M27. They are a calcium battery about 700cca and they can put up with being run well down.n A couple of years ago I was staying on the gold coast. We walked almost everywhere, the car was only driven on two days for about 1/2 hour at a time. For the rest of the time it was parked in an underground car park with the Engel 40 running all the time. This is the battery I am replacing today.

Thanks guys, and sorry I should have added that I'll be charging batteries for that 5 to 10 ah per night, and running the vehicle for around 30 minutes per day on average, which should make up for the drain.

Am I right in thinking that a marine or deep cycle battery will sulfate similarly to a normal battery when it is discharged, but the idea is to not let them stay discharged so that's not much of a problem, but the advantage of a marine/deep cycle is that the plates won't deteriorate from the discharging, whereas normal starter batteries don't like getting discharged more than a few percent of their capacity.

Anyhow the main thing I wanted to confirm was that a marine battery is okay for regular starting duties, because I've read a few things about them, and especially full deep cycle batteries, not being suited. This marine battery has a good CCA figure, but I wonder if there's more to it than that.
Thanks again.

Ive had a marine battery in my bravo for 2 yrs + still going strong. I liked it because it has the extra terminal to bolt accessories onto ie brake controller, relays etc. My only advice would be to make sure it meets the CCA requirements of your vehicle.
