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.
