How to Reset the Battery on a Hybrid or Electric Car

Why Reset the Battery?

Resetting the battery in your hybrid or electric car can help resolve a range of electronic glitches, such as dashboard warnings or connectivity issues. This process essentially reboots the car’s computer system, potentially clearing minor faults.

Steps to Reset the Battery

1. Turn Off the Vehicle: Ensure your car is completely powered down and parked safely.
2. Locate the 12-Volt Battery: Typically found in the trunk or under the hood, refer to your vehicle’s manual for the exact location.
3. Disconnect the Negative Terminal: Use a wrench to loosen the nut on the negative terminal and remove the cable. This prevents power from flowing through the system.
4. Wait for a Few Minutes: Allow at least 10-15 minutes for the system to fully discharge any residual power.
5. Reconnect the Negative Terminal: Reattach the cable to the negative terminal and tighten the nut securely.
6. Restart the Vehicle: Turn on your car to check if the reset resolved the issue.
