Why Reset the Car Computer After Battery Replacement?
When you replace the battery in your car, the computer system may lose its memory and settings. This can cause various issues, such as the check engine light turning on, the car not starting properly, or the engine running poorly. Resetting the car's computer helps to restore the default settings and clear any error codes that were stored in the system. This ensures your car's systems are functioning correctly and prevents further problems from arising.

- Wait for the computer to reset: Allow the car's computer to fully reset, which typically takes 15-30 minutes.
- Reconnect the battery: Reconnect the positive (+) battery terminal first, then the negative (-) terminal.
