The battery fit, and the system works as usual.It will, however be a few years down the road before I will know for sure that the product really works as advertised. Impossible to know now.

Great and cost effective solution for a power out battery.
It sucks to be stuck in your garage when the power goes out, this battery is the perfect solution for a power out opening provided your garage is equipped for such an event.

Fits the Budget
Purchased and installed 11/11/2024 in a Lift Master garage door opener. This is a backup battery to allow opening of the door if land power is lost. Product arrived on time and nicely packaged. I ordered two of these and both had a charge of 7V on the battery and got my garage door opener low battery alarm to shut up. Will need a charge before using for anything needing the full 12V. Will update review based on longevity. Original battery lasted about 4 or 5 years.

Perfect match for OEM
Same size, fit great, incredibly easy to install. Worked as intended right away. OEM battery lasted over 6 years! We’ll see how this one holds up but off to a good start.

Great replacement for my LiftMaster garage door opener
A couple days back my LM garage door opener started to beep at fixed intervals. Much to my surprise, it was due to the backup battery having failed. I did not even know I had a battery backup. Nonetheless, it was time for a replacement. LM brand batteries are quite expensive. Searching around on Amazon I found this. The dimensions were slightly different, so I had some doubts.However, all is well. Battery arrived safety. It was easily installed. And the opener is working great.Would I recommend this to others: YesWould I purchase again: Yes

Great battery
This is the third one I have purchased for my garage door opener over the last 7 years. It works great. Easy to install and much cheaper than the manufacturers.

Fits Liftmaster wled fine. Good luck registering it.
This installed fine, charged right up and works. The vender includes card to scan to register and get extended time. Good luck doing that! Would not let any of my computers at browsers get to the registration page. And there is nothing on the home page to link to it either. So, just assume there is NO warranty!
