🔧 Palisade - 12V Battery Replacement
On your Palisade, the 12V battery sits in the engine bay and can be replaced with basic hand tools. The key is using the correct battery type (especially if equipped with Auto Start/Stop) and reconnecting the terminals in the right order to avoid electrical issues.
Difficulty Level: Beginner | Estimated Time: 0.5-1.0 hours
⚠️ Safety & Precautions
- ⚠️ Keep metal tools off both terminals at once (short risk).
- ⚠️ Wear eye protection and gloves; batteries can vent acid.
- ⚠️ Key fob away from the vehicle; ignition OFF.
- ⚠️ If you have Auto Start/Stop (ISG), battery type is critical.
