Does Mopar Use Napa Batteries?

[zw470]

Been getting the @! auto start/stop unavailable warning the last few days so I figured I'd throw the charger on for a bit to see if that solves the problem. This is what I found when I popped the hood.

Guess the body shop swapped it out and forgot to mention it ?

To answer your question, the OEM batteries under the hood are labeled Mopar. They don’t have a brand on them.

No, Mopar does not use Napa-branded batteries. That is, actually, a very good battery aftermarket if it's new and well within its service life.

The battery disconnect switch you have is not a factory installed device, either.

They probably left the original auxiliary battery in place. They should both be replaced at the same time

That's for my winch, I personally connected it to a factory battery when I installed it ?

I have the following error code, is Battery B the aux battery?

Yes. Your aux battery is shot and it will now begin to draw down the main battery. You could be good for 6 months or 6 days. But one day, the Jeep wont start, or will die when you are driving it.

Swap out the Aux battery quickly. Since they replaced the Main but not Aux, the old/bad Aux battery is severely stressing your newer Main battery and reducing its lifespan. They are directly connected and the Main is trying to balance with the Aux 24/7 at a voltage the Aux can't achieve anymore.

No way this is a real thread… is it?

No ?

Well, sorta I guess, my Jeep really is showing the @! warning and the P00FD error code.
