Engine Starting Battery

I only got 10 years out of the Interstate 31 batteries in my Dynasty. Actually put them in a 24V machine and got another 3 years.

How long has the current battery been working? Any reason not to replace it with the same brand? I don’t have any recommendation but I’m sure you’ll get plenty of input.

wal mart deep cycle marine starting battery ,8years and still starting .and if it goes bad ? theres a wally world on every corner.

Well Sam's has good prices on batteries if you are already a member. COSTCO is #2 on the list with the same caravat. Since I'm not a member I went with DEKA

Now DEKA (East Penn Battery) is a MADE IN THE USA product right down to the lead that forms the plates. They make it in house (They own the smelting plant) no other battery company that I know of can say that. I've been happy so far battery is 5 years old now.. Shows no signs of aging that I can detect from driver's seat.. Old (OEM) batteries lasted 9 years.

Sorry, we have no idea what kind of coach/ what kind or size engine you have. Advice for a Ford V10 will be significantly different than a Cummins M11.

Basics are to make sure that the batteries meet the CCA for YOUR engine.

In many cases, fit the largest battery/batteries that will fit your chassis battery location.

Whether wet cell or AGM depends on accessibility to checking water level and your desire to do it.

In general, buy the most expensive name brand nationally available battery you can afford that has the longest unconditional 100% free replacement warranty. Pay less attention to the pro rated portion of the battery warranty, but, it is important.

The CCA rating should be equal to or greater than the battery that came in the vehicle. The higher the CCA rating, the better.

You have to decide whether you want (can afford) lead/acid, maintenance free, AGM, or, ?. Generally you get what you pay for, but, every battery manufacturer occasionally has a super nova and unfortunately, also leaves a few turds in the punch bowl.

This is interesting, my engine batteries are two 12V sealed batteries.

Sams sell Duracell lead acid batteries which are made by East Penn/DEKA.

COSTCO sells Interstate Batteries which come from one of the major US lead acid battery companies (there are only a hand full).

Good advice, but the batteries sold at Sams and Costco pretty much match or beat all major brands.

For superior performance and long life consider Odyssey AGM battery.
For economy consider Costco.

What size?

This link is from 12/2013. There are no longer any lead smelting plants in the U.S.https://www.forbes.com/sites/timworstall/2013/12/23/the-last-lead-smelter-in-the-us-closes-because-the-hippies-won/#2f571613642b
