Aux Battery

[calemasters]

your copy paste means nothing and says nothing. Your batteries have a separate warranty on top of the factory 36/60

Are you referring to the original OEM battery, or a Mopar service replacement battery? The warranties are not the same.

I agree, they are not the same. A replacement would not fall under the factory warranty.

It is a little confusing. The original OEM main battery does have a 3/36 warranty. However, if the original battery fails within 3/36 warranty period, the replacement Mopar battery warranty is either 2 years or for the remainder of the original 3/36 warranty, whichever is longer.

If a customer buys a Mopar battery over the counter, the warranty is 2 years for the date of purchase.

that’s not the warranty of the AGM series batteries. They’re 3 years.

My aux battery died

on my 2021 JL Sahara after 1200km. It got towed to the dealership and replaced under warranty.

Thank You this is all great info on Crappy Design of Secondary/Aux battery! My 2018 JLU just left me stranded in a busy intersection! #&%@! The Auto Stop/Start malfunctioned and Jeep would not start. After turning it OFF, Cycling gear lever and Turning Radio/UConnect off, it re-started. I have the "Amber" Auto Stop/Start warning on the dash and I suspect the culprit is the Secondary Battery? PS I have a new Main Battery. Edd

HaHa! LOL! I am no fan of the Auto Stop/Start. I think it is unsafe and causes excess wear and tear on motor/starter! I will get rid of AUX thanks!

There is plenty of information on how to disconnect the AUX battery and disable ESS by simply pulling Fuse 42 here in the forums...
