LiftMaster Belt Drive Garage Door Opener

Model 3850

DC Motor Belt Drive with EverCharge® Standby Power System

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 EverCharge® Standby Power System 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.
