Since I worry too much about getting stuck in the middle of our "pond" from running the stereo all day - I usually replace them every couple years to be on the safe side. Since I buy 2 every 2 years, I just buy the cheap deep cycle marine ones at WalMart. No problems... yet!

Some will tell you to get a starting battery (dedicated) and a deep cycle for everything else, but I don't play into it. If the manufacturer supplies only one battery, and it's a deep cycle used for starting as well, then I tend to believe it's okay to do so.

Ok thanks makes since to me. Do u use a ACR or anything. I have a blue sea switch with the 1,2,both,off options and I only plan on using it and switching to what ever battery I need.

Yeh, the Optima"s are expensive but I broke down and bought 2, three years ago and for me it was well worth it. One thing that I do that I'm sure everyone does is in the winter I bring both batteries in the house and put each one on a trickle charger and it keeps them fully charged and ready to go.

X2 on the Walmart batteries. I replaced mine last year to the tune of $79 each, for group 29 Deep Cycle with 875 Cranking Amps. Also came with a 2 year replacement warranty. Can't beat the price, two batteries and $50 to spare for the price of one optima. :wink_thumbup:

I also use trickle chargers during the winter and store them inside. Some simple battery maintenance like using a trickle charger (or sometimes called battery maintainers), keeping them in temps above 50 degrees, and keeping an eye on the water level throughout the year will prolong their life!

thats more what i am thinking. what is the diff in groups? And is the lowest cranking amps u would go with. So u are saying u use two starting batteries to start your boat and also use a starting battery as your house battery

i really don`t think it matters what brand you get, since theres probley only a couple of battery manufactures in the us anyway.stay with a deep cycle, i would get one with the highest cold cranking amps that i could get.also get one with the longest warranty, it stands to reason that a battery with a 7 year warranty will last longer when one with a 3 year warranty. try to purchase one from a store that sells a lot of batterys, you don`t want to buy one that been sitting on a shelf for months !

Nope, get deep cycles. They'll have more than enough cranking amps for your boat. The reason I went with a Group 29 battery was it had the most cranking amps. They're physically larger, and you might have to replace your battery holders, I did. If you've got MPI, Mercruiser recommends at least 800 cranking amps, according to the service bulletin my dealer gave me a few months before I replaced the batteries.

If you decide to go the walmart route, look for a small circular sticker on the side, that'll be the date of manufacture. I found ones that were made the month before I bought them!
