LiftMaster Compatible
I needed to replace the backup battery for my garage door after the original one died. Since we get power outages pretty often in the summer heat, having the door still work is a must. This battery worked perfectly with my LiftMaster opener. installing it was quick and easy, and the size was exactly as listed. Still works 6 months on.

Perfect replacement for OEM battery
Battery backup on garage door opener lost ability to recharge itself, causing very annoying alarm beeping.This battery was half the price of the manufacturer's brand one. It took moments to change out, and so far appears to work perfectly. Mighty Max reached out and extended their warranty, which was already superior to Chamberlain's. No idea how long it will last, but so far I am very pleased.

Good, low cost battery replacement battery
The battery was a little lighter then the original battery. Not sure if that will mean is has less power or will have a shorter life. I bought this for a back up battery for my garage door opener. It fit just fine and my “bad battery alarm” finally stopped.I got this one because it was cheap, but that was the only reason. I would recommend this if you have the money going OE would be the best because you know how long it will last.

Just Installed, So Far So Good
I have just installed this new battery, so I cannot speak to its longevity. It was very easy to install and fit within the required space. Connecting the wires was also quite easy. No complaints, appears to work as intended.
