house batteries

Hi,

If you are only getting two years you may need to think about bumping up the amp-hours of capacity.

You may also want to change out the converter to something that is a little more battery friendly.

Another good way to extend life is to add a solar system so the battery bank will get fully recharged between trips.

I should explain why only two years use. The heat in the southwest just is not very good on batteries for vehicles or house batteries.

With all due respect, the southwest heat won't affect your batteries at all if you keep them charged (floating) and replace any water that may evaporate or burned off by charging. Our desert here in SC is just as hot as it is in Tucson, and our batteries (in all our vehicles) last just as long as anywhere else.

If you're only getting two years out of yours, you need to change your method of maintaining them or get the correct "type" of batteries. You are using Deep Cycle batteries...correct? Normal starting batteries being used as house batteries won't last very long as they are not designed for that type of use and will fail much sooner.

If you have multiple house batteries, just go down to Costco and get a couple of their 6v golf cart batteries and hook them in series for the necessary 12v. They will last 5 to 7 years easily. If you only have one house battery, get a "deep cycle" 12v battery.

Make sure that they are on a charger that has the three cycle charging system that includes a "float" charge. Same with your converter/charger in your rv.

Hope this helps

Roadrunner16, your profile shows you with a 2008 RT 210P, which I am sure is the same as my 2007: twin six volt batteries. Ours lasted over six years and I replaced them last fall with new six volt golf cart batteries form Sams. They work great. If this is your first replacement of the batteries, take a look at and see when your coach was manufactured or the date on the batteries. I bet it is six years. I consider that a good life span.

Incidentally, I replaced the Chevy battery at the same time. An OEM starting battery that is over six years old was introducing the Fear Factor in yours truly. I didn't want a starting failure way out in the boonies, but I do carry a heavy duty set of jumpers long enough to go from the coach batteries to the chassis battery.

Yes PSW Thanks I ded check again. I got the 210 in 2009 in Iowa and 4 months later I had to replace the batteries because they wouldnt hold a charge. Two months later I was in Iowa again and the dealer paid the replacement cost with no questions. Your right I did get 4 years use out of them. It pay to check things before you write a form.
Sorry people.
