 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.
