LiftMaster 485LM Backup Battery

How do I know if and when I need to replace my LiftMaster garage door opener battery?

If your LiftMaster battery backup garage door opener is beeping every 30 seconds and the battery LED is flashing orange it means the battery is low. If the battery LED is solid red, then the battery is dead and cannot recharge. Replace the battery.
