Battery anyone?

Our 07 3485 SA's battery seems to be weakening by the day. It will not hold a charge very long. We don't boon dock much at all. I was wondering what type of battery to replace the original. Should I opt for one of those new AGM types or simply replace with one similar to the original. Would it be worth my investment to put two in versus one?
Thanks for the comments!

I would replace with two 6volt golf cart batteries. They are installed in series to make 12v. You can deep cycle them to 50% and they will bounce back about 1000 times and generally last 4 years if you maintain them with distiled water. They are thirsty buggers.

I would opt for 2 x 6 volt golf cart batteries if you have a charger (converter) to charge them in stages. If your converter does not charge in stages you can probably add one of these since you have a newer unit and converter. Link
The 6 volt deep cycle golf cart batteries are somewhere around $100 each. and the IQ Smart Charger is around $40.
If you go with the AGM batteries they are probably more than twice the cost of lead acid batteries. Longer life and less maintenance.
I have used the regular 12 volt Interstate Marine/RV batteries that you get from the factory with the coach and they have served me well in the past. My setup was two of them wired in parallel. Sams Club 6 volt deep cycle batteries are though well of also.

Me Too. I replaced my first one after 2 1/2 years with a Walmart Marine for about $79.00. However, I do not boondock at all. I know alot of folks use 2 6 volts and 2 12 volts and even 4 6 volts. Most of these folks do a lot of boondocking and I would do that also if we boondocked.

Right...so my sig backs this up and I'm going to go to 6v golf cart batteries if this setup starts to fail...no signs of that yet. 2 group 27's and 1 (came with Monty) group 24 all in parallel but my boon docking is 4 days supported by a 3000 Ti Kipor.
