    Most people don’t realize this can be done without removing the fuse box, without disconnecting any cables or the main battery. All you need to do is remove 2 push pins in the lower left hand corner of the inner fender well liner, pull (fold) it back and there it is, three bolts drop it down disconnect cables, replace battery, reassemble, release fender liner put the 2 pins back, Done.

      Depending on the tire size and inner liners that could be the hard way. I also don't like the wire holding the battery either. I prefer going though the top.

    There are several opnions on this. I disconnected the wiring harness under my hood on the switch. There are 2 switches on the right when you pop the hood. The one on the right is the ESS. You can disconnect the wiring harness. It disables and by passes the ESS, supposedly.

    My 2020 JLU has been at the dealer for over two weeks this time and they are still stumped. Problem on this Wrangler presents as ESS not ready "battery charging" In the last year the dealer charged, then replaced the Aux battery. Later replaced the IBS module. Works for a few days then quits. I am convinced that the IBS module is the key to my problem. The IBS module senses the voltage, current, and temperature of the batteries to control charging. If either of the batteries is not at full charge the ISB trains to low battery conditions and never brings the batteries to full charge. Some jeepers indicate that the IBS must go through 5 to 8 ignition starts with 8 hour off cycles to become trained. I will try to circle back here if I get an answer!

    2020 Wrangler and has been to dealer 100 times for the battery drain. They still cant figure it out because its somewhat inconsistent and they cant duplicate the problem. I will always catch the the dashboard and shifter box turning on and off every minute all night long and the car is dead in the morning. Problem is that I have t charge it to get to dealer and it may not be a problem for a couple days then overnight or weekend it dies on them, but they cant catch it in the act. They claim both batteries are good. I just cant trust the car on any far away trips or for important reliability trips like getting to the airport at 67:00am because I have no idea if it will be dead when I wake up in the morning.

Once replaced they ran more tests and determined that my alternator was no good. My primary battery was tested and was fine. After all was said and done total cost with labour, $1500. I believe everything should have been under warranty however they said it was my aftermarket stereo system (amp,sub,receiver) that caused the issue.
