Which RV Deep Cycle Batteries To Buy?

You should look at buying two 6 volt Interstate batteries from Costco. $89 each.

+1 for a pair or two golf car batteries.

x2. I bought 4 myself.

You asked about 12v so that's the answer I will give you. Don't care to enter the 6v vs 12 debate.
These work well if you have a distributor near you:
US Battery.
Another option is the EverReady sold at Sam's club and Batteries plus.
You want the DCC version at at Sams or the SLI24MDC at Batteries Plus. Both the same battery made by EastPenn MFG just labeled different for each store.
If you don't boondock these will fill your needs well.

If you REALLY want a 12V battery, get a 12V golf cart battery (size GC12). Sams Club carrys them but good luck in finding one in stock. They will have to order one for you.

2 6V golf cart batteries are about the same price as 1 GC12 and they will provide a longer run time.

If you have Rural King nearby check their supply out!

My two Interstate batteries are getting near five years and I will replace them this year. I am not sure one is better than the other, but I will check out the supply at Rural King as they always have good prices and selections, especially at the one in Leesburg which is close to The Villages and their thousands of golf carts.

if your pluged in 80% of the time? just go to wal mart get the two biggest that will fit your box . I use them in my boats and rv .boat batteries are 5yrs old and rv 3trs old .no problem. if your on battry 80% then get two agm.s
