After having battery issues with my 2020 Jeep Gladiator Rubicon, I did a little research to see if I could pinpoint the problem. From what I can gather, the smaller auxiliary battery had gone bad and was brining down my main battery. Since I used the Tazer 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. Here's the link to the battery I used: https://www.autozone.com/batteries-starting-and-charging/battery/p/duralast-platinum-agm-battery-h7-agm-group-size-94r-850-cca/319458_0_0
