I have to replace my battery's and I want to know what I should replace them with?

Any help would be great

Are your batteries in the original location in front of the engine? If so, those are small batteries, so I would spend a little more to up the capacity, an AGM battery would be good. I have had really good luck using Batteries Plus for "standard" marine batteries. Their private label batteries are made by Penn-Yan/Deka which have been great for my application.

My batteries are located in the lockers under the back two seats. They are EverStart Maxx-24S part Number and Cranking Amps 875 Cold Cranking Amps are 700. It looks like they are a Wal-Mart part

I have Interstate marine batteries, been running for 4 years.
I remove them from the boat every winter and put them on a trickle charger.
They are still in super shape.

Intestate, Deka, Optima are all good brands, with optima dropping in quality ever since they moved production to mexico.

make sure you keep the CA and CCA the same, if you can, get one with more Amp Hours. that will give more reserve capacity in the cove with the stereo on. short of that, grab a third RV battery and daisy chain it to one of the stock batteries with 4 gauge or bigger (ought or bigger would be best for a big stereo)

don't go too over board with the batteries though or your alternator may not be able to keep up. most are only capable of 100 amps of charging

My understanding is that you're not supposed to mix, starting batteries with deep cycle batteries, only because they take charges differently if you run say the deep cycle down. They generally don't like to charged, especially by an alternator too hard.
