Our newest opener and newest addition to our Elite Series line, the LiftMaster ® 3840 3/4 HPS ® DC Motor Screw Drive with EverCharge ® Standby Power System is the only screw drive garage door opener on the market with fully integrated battery backup technology. It can power the garage door opener for up to 40 full cycles within a 24-hour period in the event of a power outage, and recharges automatically when the power comes back on. The safety and security features will continue to operate as well, ensuring your family is protected during a power failure. Not only that, it has the added features of our exclusive screw drive opener design: it is specially engineered to run smoothly and quietly in extreme temperatures, and has a self-lubricating, maintenance-free rail system.
