Garage Door Opener Battery Backup
You have just returned home after a lovely evening only to find there has been an power outage. Your garage door
opener works on electricity so you cannot open it and neither can you get into your house through the garage. That
is, you cannot get in unless you have a garage door opener battery backup system installed.
Remote garage door openers need electricity to work, which can leave you in a bind if you come home to a power
failure. Fortunately, you can have a battery backups installed which will operate your garage door drive system for
a minimum of two or three full cycles without the need for any mains electric connection. Once the power is
restored, the batteries in the back-up unit will be automatically recharged ready for the next time the power goes
The battery in a garage door opener back-up system should last at least three years. In cool climates, it will
last longer than if it is in a warm part of the world. When the backup unit is new and charged up completely, it is
reasonable to expect that it could raise and lower your garage door twenty times or more. Even if the electricity
has been out all day, there should be enough power in the back-up battery to keep operating your garage door opener
until such time as the outage is over.
The Chamberlain Liftmaster battery backup system sits on top of the garage door opener and plugs into the back
of certain opener models. Universal backup units such as those made by ONkor are housed in a separate box which can
be fixed to the wall or roof beam and are designed to provide temporary power in the event of a power outage.
The backup system for a typical garage door opener, such as the Chamberlain Evercharge, will probably be
equipped with a small LED light to indicate when the batteries are being used. They also might include a buzzer to
alert you that the door is moving under battery power. The backup that can be used with a Chamberlain opener system
is designed to be strong enough to keep all the safety features of the opener and the door powered and
When you first install an external garage door opener battery backup system, you will need to let the battery
charge fully for about six days. When it is no longer charged up, there should be a small light on the unit that
will alert you to the failure.
If you are going out of the house and the power is out, you can remove your garage door opener, or at least
disable it, and open the garage door manually.
If you need to throw the old battery away, make sure you find a recycling drop off, perhaps in a hardware store.
It is not good for the environment to drop batteries in the trash can.
Installing a battery back up for your garage door opener is a very good idea, since it is estimated that some
100,000 homes in the US suffer power failures each and every month. On top of that, the garage is also the main
point of entry to many homes. If you have a battery backup in place, you will not be trapped in or out of your
garage or house.
