Battery Backup

The integrated battery-backup system allows the garage door opener to continue operating during many household power outages.

Battery-backup performance depends on:

The battery is a maintenance item and may require replacement after extended service.

Use only a garage-door-opener-compatible LED bulb to reduce the possibility of remote-control radio interference.

Safety Warning

Garage door openers operate heavy moving doors and must be installed only on properly balanced garage door systems.

Improper installation or adjustment can result in serious injury, death, or property damage. Spring-system repairs and door-balance corrections should be performed by a qualified garage door professional.
