Product Review
If you have ever lived in a hurricane zone or anywhere with significant seasonal weather, you know that power outages are often a way of life that you just have to embrace. Having a battery backup like this one for your garage door opener takes out the frustration on these unfortunate days.
The Liftmaster Battery Backup is a wonderful addition to any garage door system. It is so easy to install, you will wonder why you didn’t put one in before. In many of the Liftmaster units, it simply slides into place into a predesigned seat, and with a few simple actions, is ready to charge.
It is a closed acid system similar to the battery on a motorcycle. The acid is already added so that isn’t a concern, and just like a sealed deep cycle battery for a boat, it works best when on a constant trickle charge like the one implemented by the unit it is intended to power.
The battery is powerful enough to engage the opener, while still being light enough to sit in the unit and not tax the mounting bolts holding the unit the ceiling. At just 3.13 pounds, you might not think it could have the juice to lift a garage door, but it will every time without fail, unless the battery becomes old or faulty from poor charging.
This model of battery will work with plenty of Liftmaster openers. It is already retrofitted into some of the older models and will work perfectly with the new design without concerns of alterations.

What the Users Say
For the most part, users of this battery backup have been impressed with its power and style. It fits into many of their existing Liftmaster units, and if they get a new unit without one already installed, they are happy to add it for peace of mind. They like that it is lightweight over other sealed backup battery types, and that the Liftmaster system is ready to accommodate it.
Anyone who has had to use theirs during a power outage has given this big thumbs up and cannot praise the concept enough. Many have actually said “thank you” for the convenience, the style, and the power of the unit when they needed it most. And for the DIY crowd, having the ease of personally installing it into their unit has been a huge boon.
There have, as always, been some issues. Some users have found it incompatible with their model of Liftmaster and have raised concerns with the company over this oversight. And others have found the battery to last a substantially shorter duration than other batteries they have owned in the past, and that includes the ones they purchased from Chamberland.
