I have had two sets of Interstate Workhorse U-2200 6 VDC batteries in my coach. The first set were the original ones that came from the factory. They lasted 7.5 years and I was not very careful when taking care of them. The second set only lasted 4.5 years with excellent care and maintenance before two of them were boiling all of the time and the sides of the batteries had expanded dangerously.

I took all four out this past August and replaced them with 4 Sam's Club 6 VDC batteries model GC-2. They were only about $70 each whereas the U-2200's were over $100 each.

The GC-2 seem to be working great but we shall see how long they last.

Batteries are hit and miss nowadays. Everyone has a wildly different story with the same batteries. Weird. Its like that same brand is made at 5 different places.

GC 2 is a brand Energizer and it is 6V. I was told they called it GC 2 as a short for Golf Cart which would be a deep cycle.
The voltage for batteries on your particular installation I do not know

We replaced our 4 Interstate U2200 6v batteries with 4 Interstate GC2 6v batteries from Costco--basically they're the same. If I'm not mistaken the GC means Golf Cart, but could be wrong.. Costco price was $96.20 including tax with old battery core turn-in.

My choice would definitely be 6v batteries for coach batteries.

Good luck and safe travels...

Hey Guys....

I have 4 12 volt batteries for the coach and I am thinking that I should replace them with 6 volt batts. The compartment that they are stored in is really tight and I would love to be able to check the fluid level regularly... Do you have any ideas about how to replace the batts and then monitor the fluid level? Should I go with sealed batts that require no maintanance...or should I find a way to put new batts in a tray that can be monitored???

My batts are quite old and I need to replace them and I would love to hear your opinions....

Replaced our 10 year old Interstate U-2200's with new Interstate GC-2 batteries earlier this year. Cost was around $115 each, but I got such good life out of the originals I went with the same ones.
GC-2 is an industry wide designation for the size/rating of the batteries just like Group 27 is.

AGM 6V seem to have many pros and only a financial con. Basic RV life and shore power hook ups then Costco Sams Club Walmart is fine . Boondocking for extended period demands looking up vonsumer reports etc Good luck out there.

I have a Monaco Dynasty owner friend who beta tested a set of of these new type of house batteries for a company located in Florida. His name is Ron Jones and you can read about his testing here.

RVing Tips- RV LifeStyle - RV Travel Full Time RVing - RV Maintenance - RV Repair

Here is the website for the company who makes them. They are lithium ion batteries.

Lithionics RV Li3 Batteries

Since his beta testing, I have another Monaco friend who just installed two of the same lithium-ion batteries into his 2003 Diplomat.

They are pricey but then again, you get what you pay for and a lot more with these batteries.

I just replaced my 11 year old chassis battery and my 4.5 year old set of house batteries in Fairbanks Alaska this past summer. I bought them from Sam's Club and they are all the wet cell type.

They next time I have to replace batteries, it will be from this company for sure.

We use this system for adding water to our 4 coach batteries:

Qwik-Fill and Pro-Fill RV Edition | Flow-Rite

Works great, been using it since 2006 and so far no problems with the system.

I looked at the site. There seems to be two different systems. Is it the pro-fill rv system you have? Also, the description says it fills two batteries, do I need two systems for my four house batteries?

We have a 2011 Canyon Star. It originally came with 2-12 volt batteries. There is not enough storage in a 12 volt battery and they did not work for us at all. We have solar 2-110 Watt units. We went with 2 6 volt batteries, hoping that would give us enough storage. They work but do not have enough storage to operate TV's or whatever. I believe that you need 4-6 volt batteries if you want to boondock for any length of time. Whether you are charging your batteries with a generator or travelling, 2-6 volts do not give you enough storage. I am assuming that you have an inverter installed in your unit.
We are having another battery holder installed so that we can add another 2 so that we have 4-6 volt batteries. We have boondocked often and it is nice not to have to listen to the generator operating so the solar panels sure made a difference.
Happy Trails
