Sean Foushee: We were having a Liftmaster Elite 8500 installed with our new garage door, so I ordered this backup battery system online ahead of the installation (sold through 365 Garage Door Parts; their shipping and support was excellent). Our area typically experiences large storms during the spring that often knock out the power, sometimes for days. So, this option was one of the main reasons we went with Liftmaster. After installing the unit on the wall perpendicular to the opener it took a couple of hours for the light to register that the battery was fully charged. It wasn't even a full 24 hours later that our area experienced a 6 hour blackout and this little unit worked like a charm; it's a fantastic system that has already made a big impact.

I feel that the product is fine. My original battery lasted 9 years. The replacement battery that I purchased WOULD NOT CHARGE PROPERLY AND I ASKED AMAZON TO CONTACT THE SELLER. I EVEN TOLD THEM TO MENTION THAT I CALLED LIFTMASTER AND THEY TOLD ME THAT AFTER 72 HOURS THE BLINKING GREEN LIGHT SHOULD TURN TO SOLID.. A WEEK LATER IT WAS STILL BLINKING...
MUCH TO MY SURPRISE THE SELLER WANTED ME TO CALL LIFTMASTER AGAIN. LIFTMASTER WAS SURPRISED BY THAT AND THEY FORWARDED ME A NEW BATTERY BACKUP W/O GOING THROUGH THE SELLER. THE SELLER IS A #1 IN MY BOOK.

Our original Battery Back-Up System was installed at the same time as the new garage door and opener over 8 years ago. It has worked flawlessly until this past week when the red light and beep let me know it was time to replace the batteries. The cost of the batteries plus time to rewire them (new batteries do not have the same type connectors) overshadow the cost of an entire new unit. PLUS, with a new unit, you are assured all new electronics. Nothing more frustrating (and somewhat costly) than installing new batteries and then finding out that something deep inside the electronics package has gone awry and you are now going to have to replace the whole unit anyway! Not quite as simple as replacing the flashlight batteries and finding the bulb has burned out, although I'll bet we've all been down that route at one time or the other and it's frustrating!
It's comforting to know that when my spouse arrived home from work late at night, the door would always open, no matter the weather or electrical issues we might have due to storms or whatever. She could drive into the garage without worry and close the door behind her before exiting her car, in the...

Buy this now - because when you come home to a house without power and you're sitting outside your garage door-it's too late. Oh sure, you can order it afterwards, maybe you'll even appreciate it more because you can "remember the time we had to go through the house, manually open the garage door and then manually lower it?" Super easy to install - and does what it promises. It operates your garage door opener and the light when the power is out. It will sit there silently charging until you ask it to do its job.
Mine arrived and wouldn't work. Opened up the unit and discovered the fuse had come loose during shipping. I snapped it into place and works as promised. Guys - take care of your wives - give them a battery back-up for the garage door.
Unless your garage is full of stuff and you park in the driveway. . . that's another story!

Steve Paul: Save yourself some $$$. If contractor installs a compatible LiftMaster, in my case an Elite 8500C with MyQ Internet Gateway, you can buy the battery pack from Amazon and simply plug it into the motor unit. That's what I did. Connectors are pre-wired.
Takes 1-2 days to fully charge. No need to plug into A/C receptacle. Only replaceable part is the batteries and expected to last 3-5 years. Sounds about right.
Genuine unit. Not a knockoff.
PS With two garage doors, I bought only 1 battery back-up unit connected to my wife's side. Your choice to buy two
