Overall Rating:
4.6 out of 5
Now when the power goes out, your garage door opener will still work. The LiftMaster® 3850 is the only 3/4 HPS®* professionally installed opener with a fully-integrated standby power system. It will operate the garage door opener for 40 cycles within a 24-hour period, and recharges automatically when the power comes back on; an audible signal tells you when the power is out and the Battery Backup is in use. The safety and security features will continue to operate as well, ensuring your family is protected in a power failure. The opener also features smooth start and smooth stop to reduce the noise of the garage door as it opens and closes – perfect for homes with a room above the garage.
