I have a 2006 Alpine Apex 40FD with Chassis Interstate Batteries 31 MHD that need to be replaced AGAIN. I am very unhappy with these batteries as this is my 3rd failure. Any ideas on a better battery?

Maybe there is something causing the failure, not the batts?

I have the same batteries in my 04, and they lasted 5 1/2 years, after the first set lasted just under 5. I bought them again. I suspect you have some other problem that is killing them. That or I am very lucky.

I do not think it's your batteries. A much more likely cause is your converter and how it charges batteries while sitting. Check your converter for identifying name and model #. Then, look it up on the web. What you need for good and long battery health is a multi stage converter and never let batteries sit with a low charge.
How do you store your coach, Is it plugged in in storage, and do you have a multi stage charger are very important questions that relate directly to battery life.

Agree, dont think its the bats but since it is your chassis bats that are failing, I suspect you may have a problem with you alternator charging levels......Have you notices anything unusual with the the bat charge level when you are driving--normal levels are around 13.8 to 14.2.

Thanks for all the inputs. San Diego RV found a failed charging solenoid and a blown 250 amp fuse. They say it is possible the failed solenoid could have caused all the problems by not letting the chassis battery being charged properly. It is all being repaired and hopefully my battery failure problem will be gone. Thanks again for the inputs.
