LiftMaster Garage Door Opener Battery Maintenance Tips
To ensure the longest lifespan and reliable performance, regular maintenance of your LiftMaster garage door opener battery is essential. Here are some helpful tips:
1. Monthly Testing
It’s important to test the battery monthly to make sure it’s functioning properly. To test, disconnect the power to your garage door opener, then attempt to operate the door. If the opener operates as usual, the battery is functioning correctly.
