Today, we’re going to be replacing the auxiliary battery in the Jeep Gladiator, and also replacing the bigger battery as well. The auxiliary battery has been causing issues, displaying messages like “aux temporarily not available while charging” and it’s almost three years old. To ensure the problem is solved, we decided to replace both batteries while we’re at it.
The cost difference between the two batteries is $50, with the Walmart battery having a four-year warranty compared to the three-year warranty from O’Reilly’s. This influenced our decision due to the better warranty offered by the Walmart battery.
Before we start, it’s important to disable the module underneath the battery to allow it to reset with the new batteries. Both batteries have been charged and we’re ready to proceed with the replacement.
We decided to access the battery through the inner fender rather than removing the fuse panel, as it would involve dealing with the electrical systems of the truck.
During the process, we encountered some unexpected challenges like breaking the security socket when trying to take the tire off. This led us to leave the tire on and remove the inner fender to access the battery.
Once the battery was accessible, we had to disconnect the wiring and remove the battery from its compartment. The difficulty in getting the connectors off was the hardest part of the process. However, with some trial and error, we were able to overcome the challenge. After replacing the battery and reassembling everything, we were pleased to find that the replacement went smoother than expected.
After completing the replacement, the Jeep Gladiator started up with all lights functioning as they should. We were satisfied with the outcome of the battery replacement. If you have ever done this replacement, we would love to hear about your experience.
