After having battery issues with my 2020 Jeep Gladiator and getting tired of start stop issues, I decided to delete my Aux battery. When Big Brother gets involved in vehicle production, the outcome is normally worse for the consumer. When the Aux battery goes bad, it typically takes the main battery with it, I would recommend deleting or bypassing the battery if you do not use the start stop function.
Since I used the superchip computer to keep the auto stop-start feature disabled on my JT, it stood to reason that I should be able to bypass the smaller battery altogether. So, that's exactly what I did with great results.
