How to remove auxiliary battery jeep gladiator?

As a Jeep technician, I've replaced dozens of these auxiliary batteries in Gladiators. This is actually a pretty common issue with the JL/JT platform. Important safety first:- Disconnect the MAIN battery negative terminal first- Wear safety glasses and gloves- Have the vehicle in park with emergency brake engagedStep-by-step process:1. Remove the main battery - yes, you have to take out the primary battery to access the auxiliary2. Locate the auxiliary battery - it's tucked underneath, towards the firewall side3. Disconnect negative then positive terminals4. Remove the hold-down bracket5. Lift straight up - it's a tight fit, so some wiggling may be neededPro tips:- The auxiliary battery is smaller than the main (Group 94R vs AUX14)- Consider replacing both batteries if they're similar age- Reset your BCM (Body Control Module) after replacement- Use a memory saver if you want to preserve radio presets and other settingsThe whole job typically takes 45-90 minutes for a DIYer. If you're not comfortable with electrical work, this might be one to leave to a professional though!
