The Newer Premium LiftMaster and Chamberlain garage door openers feature an internal battery backup that will operate the garage door opener in case of a power outage. The garage door opener will emit a beeping sound when it is operating off of battery power or when the battery is no longer able to recharge. A fully charged battery will provide power to the garage door opener for 1 to 2 days of normal operation when power is lost, and when power is restored it will recharge within 48 hours. While the garage door opener is operating using battery backup power the light bulbs will not turn on to conserve battery power.
LED DIAGNOSTICS
Garage door openers that are equipped with a battery backup will have a LED diagnostic to indicate current battery status.
