What Kind Of Battery Does LiftMaster Garage Door Opener Take?
The type of battery your LiftMaster system uses depends on the component—whether it’s the wall control panel, remote control, keypad, or the backup battery inside the motor unit.
1. Remote Controls

- Lifespan: Typically lasts 1–2 years under normal use
To replace:
- Use a flathead screwdriver or coin to open the remote’s casing.
- Replace the CR2032 battery, ensuring the “+” side is facing up.
- Snap the remote shut and test operation.

Battery Maintenance Tips for LiftMaster Openers
1. Check Batteries Annually
Even if your system seems fine, it’s wise to check and test batteries once a year to ensure they are functioning at full capacity.
