How to Replace the battery terminals in your car

Connect battery memory saver for backup

Don’t skip this step. A battery memory saver supplies current to avoid erasing the computer, radio, keyless entry and clock memory settings. It will also save other critical data, including engine monitor status that will turn on the check engine light.

Here’s how to do it:

• Plug the battery memory saver into your vehicle’s 12V power receptacle.
• For best results, always use a new 9V battery to power the memory saver.
