For years I have had very good luck with batteries.

I think the biggest issue is how you store the battery.

I have always stored my campers with the battery switched off from the converter or the battery disconnected. I have used two different approachs throughout the years. Both seem to work great and I have gotten battery life of 6 to 8 years.
- 1st: battery tender left on all the time.
- 2nd: battery storage method, let the battery discharge over time, but not to less then 12.4v and recharge for 24 hours with stand alone charger. Do a 24 hour charge to top off the battery before trips.

Most camper don't have a great charger. If I'm camping with shore power. I switch off the battery from the converter after 24 hours of charging at the camp site, and re-start it the night before we are heading out to top off the battery. There is no reason to keep charging a fully charged battery the entire time you are at a camp site with a not so good charger. But even if you leave it on for the 2-3 weeks of camping each year its no big deal. It's the 48 to 50 weeks of improper storage that does the most harm
