Honestly- my knowledge is limited on this, I just need one that fits stock box and doesn’t cost a zillion dollars. Box is standard ~13” x 6” size. Looking for decent quality that people have had good luck with.
I never have a choice, it seems I always discover they won't charge once I'm on the road. So I'm a WalMart man. I believe they come with a 2 year warranty. Deep cycle is the best, they don't die from discharge / recharge cycles.
Then just go to the auto parts store and get one. Don't get one from Wally world. I bought a car battery from the once. Never again Sent from my SM-G960U using Tapatalk
i just get the $75 deep cycle ones from advance auto parts. need to replace em here in FL every 3 years no matter what. Just sold my 27' toyhauler to a friend, and had to put new ones in the day i sold it. LOL.. they were right at 3 yrs old
Your bet bet, if you have the room, is to ditch the single 12V battery and get yourself a couple of the Trojan T105 6Volt batteries. Using a series hookup for the two batteries will provide you 12 Volts and your Amp Hour rating is 225-230....and they are made to provide a LOT of deep cycles, as they are golf cart batteries. They are FLA (Flooded Lead Acid) and of course they will require that you check the water level in the batteries every couple of months and add distilled water as needed. I got mine locally, a couple of years ago for $125/each plus the core charge. I read on some of the RV forums I'm on of guys getting 8-10 years out of a set of them.
Trojan makes AGM batteries as well. Their group 27 AGM battery tested very well in sailboat testing i read.... like best in category. And yes using trojan 6v in series was the standard from sailboats back in the day. They focus on deep cell and have a very good product.
Trojan AGM golf cart battery. Can find them for about $120 each, can get a water kit pretty cheap and will save you from having to go in there if you get wet cell. I sure 4 Trojan 6v in my boat for trolling, 4 in series for 24v trolling motor. They seem to hold a charge much longer than any others I’ve used.
Don't use ours off the grid remotely enough to be concerned about amp hours and such so I just get wally world marine batteries.
