Battery Backup (If applicable) The battery backup allows access in and out of your garage, when the power is out. When the garage door opener is operating on battery power, the garage door opener will run slower and the lights, Timer-to-Close, and remote close features are disabled. During a power outage the battery supplies power for one to two days of operation. For maximum battery life and prevent damage, disconnect the battery when the garage door opener is unplugged for an extended period of time.
