Adding a battery back-up for your garage door opener is an important safety feature. A new law in California that requires all new garage door openers to have one is a good idea for everyone. The idea is that you can be trapped inside the garage if there is a power outage due to a fire in the home.
Upgrading your garage door opener with battery back-up provides peace of mind for your whole family. You can access the garage anytime during power outages, due to severe weather, emergencies, or planned outages.
When upgrading your opener, we recommend the Liftmaster battery back-up model 8550W.
