I bought mine from Costco.

CaptainGeezer, you probably made a wise choice by replacing the old battery with a like new one. This will give you a bit of time to enjoy and learn more about your new MH. One thing about older MH'S is they often use a single stage converter/battery charger. These have a bad habit of overcharging the battery and boiling the water out, effectively killing the battery. A good future upgrade is to invest in a multi-stage charger to improve battery life.

Try your local NAPA auto parts store. Our 2013 Winnebago Adventurer came with 2 NAPA deep cycle group 31 batteries. In your case I would avoid AGM batteries. They require a more sophisticated charging system than the one that came in your motorhome. In all likelihood you'll destroy them.

The only real advantages of AGM's over flooded cell (standard lead acid) batteries are that they can be installed in any position, including upside down, and they are more vibration resistant. Most AGM batteries have less power output than a comparably sized flooded cell battery. You can expect 6 - 8 years of service from a quality set of group 31 flooded cell batteries. You may get an additional year or 2 out of AGM's but they are triple the cost of flooded cells.

Look into Interstate DCM series of batteries. They are a AGM deepcycle that is made for electric wheel chairs. Go to a local store that sells medial supplies or services wheel chairs. Just make sure you charge them properly.

I agree with Rockwood. If you only have one battery, it's not worth the fuss or the expense. You could replace it 3 times for the money you would spend on a Trojan deep cycle 12V.

Sam's club usually has them
Costco can get 'em (May or may not have in store)

The most popular DEEP CYCLE is the GC-2 Six volt.. Now think for a minute what does GC stand for? (Hint: Golf Car) .. Yup any Golf Car dealer WILL have 'em, and any Golf Course can get 'em. (But you'll need to make friends with someone at the Course). Batteries Plus can also get them but I'd try Sam's. or Costco first. Suspect Sears can get 'em for you but never tried.. I went to DEKA myself .

Bought mine at Precision Auto... Installed a switch to remove the Battery from the system when not being used, so eliminate removal of cables. When I am hooked to my truck, it should be on and get charged, but when we returned from recent trip, the battery indicator read "recharge".. The voltage read 12.67V... I didn't read the voltage after unplugging at KOA. I left the switch in the on position both times only removed when I was parking the TT.

U.S. Battery 12volt XC2, are a true deep-cycle battery. I just went through the learning process about deep-cycle and "hybrid" deep-cycle batteries. I now have Exide "hybrid" batteries, I'm going to change to U.S. Battery when the Exide's fail-again.
You can buy them through Amazon if you wish.

I was another one that went with the 6volts. I grabbed 6 of the Trojan T-105's.

I found a local golf cart guy whose goal it was to "own the local battery market". He was buying Trojan's (and not just the T105's) by the truckload. Selling them to rvers, solar installers, golf cart users, etc.

When I purchased I paid only about $5 more per battery then Costco was getting for their 6 volt golf cart batteries at the time and Trojans are one of the more highly rated batteries.

So I definitely recommend calling around the golf cart and solar shops, and if you can find someone who is trying to take over the local market place you might just get an awesome deal like I did.
