Battery replacement brands

A little more information is needed. Residential refrigerators do not run on twelve volts please explain. Most use 115 ac. Are you using a inverter?

Al, I do have an inverter. Bob

We have Optima marine batteries. We've had them around 4 years and they still work fine.

Optima would be the worst choice for this situation.

Find the biggest meanest Group 29 agm batteries that will fit.

I use 4 GPL-4CT 6v Lifeline batteries. Not cheap but they get rave reviews. In my 3rd year with them. So far so good.

Must replace my 2 interstate 12v batteries after 5 years. One is for my residential refrigerator and the other runs everything else. What brand battery do you use? Any particular reason for that brand. Thanks for the info / opinion. Bob

Replace with the same Interstate RV batteries from Costco , great batteries warranty etc

If you don't want to fool with battery maintenance (checking water levels, topping off, dealing with corrosion due to gassing) go with AGM batteries. As noted, Lifelines are hard to beat. Full River is another brand that holds up well. I'd go with two pairs of 6volt GC batteries (each pair wired in series to make 12V). Sam's sells Duracel AGM's that are reasonable priced.

If you don't care how much you spend, go with lithium.

I just replaced my 2 group 29 batteries with 2 Lifeline Group 31 batteries... Had them on my last fifth wheel as well...

Yes, just put everything on AUTOMATIC and turn off tour brain.

I don't use an inverter, but have been using 2 6v golf cart batteries from Sam's for years. Had I the funds, I'd build a lithium battery from Nissan Leaf battery modules. For the same weight as my 2 6v batteries, I could have nearly 4x the amp hours.
