Here’s a guide from Orange County Garage on the benefits of a garage door opener backup battery.
What is a garage door opener backup battery?
It’s a small 12 volt battery that feeds the garage door opener power in the event of a blackout. There’s tons of available models, from manufacturers such as LiftMaster, Chamberlain, Mastercraft, Linear, and Genie. Liftmaster has made these devices since 2003 so we recommend their products – some of which come with the battery inside the housing of the motor, and some where it’s over on top of the housing.

Are garage door openers battery expensive?

What if I didn’t choose the optional backup battery when I purchased my opener?
In this case, you can choose to manually open the door during a blackout. Pull the red emergency release cord, disengaging the trolley, manually lift the door, remove your car from the garage, then close the door and re engage the trolley by reconnecting it to the release mechanism. If you forget to reconnect the trolley, anybody can manually open your garage door, leading to a security risk. You can also install a side lock on the inside of the door, which allows you security when you push the steel bar of the lock into the vertical track. Just make sure to disengage this lock and reengage your garage door opener once power is restored.
