Batteries and our vehicles

[pjohnston]

So I am going to open a holiday can of worms with a couple of questions.

First the important stuff: 2021 Willys S Eco-Diesel, 64,200 miles, I bought it new a hair over 2 years and 1 month ago. It is my daily driver.

Question #1-I still have the original batteries in the Jeep. During this really hot summer in Arkansas, should I pre-emptively replace them or continue to push my luck and be stranded a couple hundred miles from home. I cover about a 5th of the state (Northwest) for my job. Over the years, 90% or so of my batteries have failed in the heat of the summer. How long do we expect the Mopar batteries to last?

Question #2-If I do replace them, what recommendations might you all have? Both brand and size/model number. Especially for the small one. I have had really good luck with Duralast and Interstate over the years.

Now I will just sit back and wait for the fun to begin..........

There are a lot of threads about the batteries. The average life is about three years. Since you do a lot of long distance driving, they should last quite a while. It's the short trips and sitting unused that takes a toll on the batteries in these trucks. You'll know it's time to change them when you start getting the ESS or Aux Switch unavailable messages at startup.

But I have been getting those warnings randomly for the past 2 years...

Check your battery voltage after the truck sits a few hours. Use a real volt meter at the main battery.
Check the voltage with the truck running.

If you don't drive more than 30 minutes at a time it won't keep them charged up.

Lots of threads on the batteries including suggestions for brands and so on
