why would 2 6 volt batteries last longer then the 12 volt. we have 2 12 volts in our 5ver. what am i missing here
thanks,

It's all in the weight of the lead. I have 2/12Volt RV/Marine that meet my needs fine. I will happy to get three years out them. If I had 2/6Volt Deep cycle I would expect them to last 6 years or more. There plates are heavyer, and generaly can give up more amps, can take more charges almost twice as many. But they take longer to recharge and tend not to give up there amps as fast as the RV/Marine type battery. Good Luck and happy camping.

In theory I suppose two 12 volt deep cycles would last the same as two six volts if they were constructed the same and came out weighing the same with the same amount of lead inside. I have ran two 12 volt deep cycle batteries from Costco and they lasted about one year. I then replaced them with two Trojan t-125's which lasted three years. The Trojans weighed a lot more and were bigger batteries. The average weekend warrior RVer does not need 6 volt batteries just to travel to a park and plug in. If you plan on spending several months boondocking and running solar you will probably end up with 6-volts. They last longer. The heavier lead plates are designed for deep discharge and more recharge cycles. I am guessing the Trojans weigh about 65 pounds each and the deep cycles maybe 40 each. The Trojans cost more so they should last longer.

You are not missing a thing. Care, usage and maintenance will determine the life.
For immediate usage, amp hours are amp hours. Same rating = same energy output before recharge.

SM,
The stouter construction of industrial quality batteries, including golf cart batteries, will allow them to live through more discharge/recharge cycles, even with the same care, usage, and maintenance as recreational grade deep cycle batteries.
I'm free of prostate cancer for 5 years now.
All men over age 50 should get an annual PSA blood test. Mine had a low reading, but the yearly jump was significant. The biopsy showed cancer just entering the aggressive stage. Dr. Hackenslash removed it.

I couldn't agree more. Our present 5'er is the second RV that I've used 2 x Interstate's U-2200 deep cycle 6 volt golf cart batteries. Three months at a fishin' camp with no hookups and 2 x 75 watt solar panels to keep those puppies charged up is proof enough for me that they work much better then 2 x 12'ers in parallel operation. It was stated above that if a 12 volt battery had the same weight factor as a 6 volt battery then the output result would be the same. Sorry to say this is incorrect. If the 12'er had the same lead weight as the 6'er then the plates in the 12'er would be smaller then the 6'er since the 12'er has 6 plates vice the 3 of the 6'er. The secret is, as stated, the number of recharge discharge cycles and of course how a person looks after them......................

Two 6 volt bateeries will have more amp hours than 2 12 volt batteries. If you don't believe me, go to Interstate Batteries website & look it up. However compare similar sized batteries. 6 volt batteries (golf cart style) can be deeply discharged more than 12 volt deep cycle batteries. You are right about maintenance & the most important factors are keeping electolyte levels to the proper height by adding distilled water, avoiding completely recharging the batteries & keeping all connections clean & tight.

The 6V batteries have more amphours. I run 6 6v batteries and have a total of 660 amphours. 2 6V = 3 12V batteries.I also have 420 wats of solar.After talking to several solar companys they all said that the 2 6V in series = 3 12v batteries in capacity. Mine are 2 six in series x 3 parall. I do a fare amount of boondocking. I can also run the microwave off the batteries. Just upgraded the system looking foroward to trying it out. Here is a site to check out

Hope this helps.

I ran with 2 12V for many years. We do a lot of dry camping. If we were good we could last for 4-5 days. When we moved up to a 5th wheel (and got older)we wanted more power and didn't want to worry about time. We changed over to 2 6V and can go 4-5 with a larger rig and more power usage. The 6V also last longer.

Troy, check out this web site. I think you will find a good write up on battery and how to take care of them as well as meny other RV related subjects.
