New LiftMaster 485LM Battery Backup for Garage Door Openers 3840 3850 8360 8550
Users say:
This product is a great replacement for a dead Liftmaster battery, easy to install, and works perfectly. It is twice the price of a standard battery, and the two different sized leads make it easy to purchase. The battery is rated to last only two years, but it is a perfect duplicate and helps avoid being locked in or out of your garage.
