2015 Conerstone 45B - have to replace the chassis batteries, replaced the house batteries last April. I’m in Atlanta for a month so I have some time to see what others owners have experienced, would appreciate any tips and recommendations on brand, capacity and etc.

Thanks

Anything manufactured by East Penn. Duracell sold at Sam's are East Penn, best price, but not all Sam's Club have the AGM. If not see if they can order them.

There's like 3 major battery suppliers who make 90%+ of the batteries on the market. Pick one. They're all decent.

The chassis batteries are usually not AGM but sealed lead-acid. They are probably Group 31, used on most trucks in groups of 2 or 3.

Except the OEM Discover/Relion. The are at the bottom the battery chain. JME after owning 3 sets, none of them lasted to the two year mark. The East Penn in the 14 were 4 years old when I sold the coach and still holing a great charge.

You are needing 31 series heavy duty starting batteries with threaded post. You can reach out to any auto parts store or NIRVC in Atlanta

Yes, you are NOT looking for AGM for engine (chassis) start batteries. I would recommend standard trucking batteries. Discover/Relion Batteries, are in my estimation, junk found on new coaches and which die quickly in normal use. Particularly bad when used as house batteries.

I agree with Chuck.... East Penn manufactured flooded cell batteries are pretty good batteries for a reasonable price. I would NEVER consider Relion or Discover brand name batteries as replacement. Spend your money where it is likely to do some good and last more than minimal expectations.

Yep, East Penn makes some good stuff for sure.
