Question: Will this battery fit in the lift master 8500 battery backup?
Document: I chose this rating because this product is for a simple and specific purpose, to serve as a backup energy source in the event of power outages, for a specific Lift Master Garage Door opener. My purchase was based primarily upon need. Less costly than changing an entire garage door opening system.It also receives this rating as there is no way to actually test the life or charge it holds.
Installed this battery in my Lift master garage door system and it worked great.I also changed the incandescent bulb that was next to it, to a fluorescent bulb to reduce the heat near the battery.I thought the original battery may have failed because of the heat from the bulb that is very close to it.
Easy to install, and now we have a battery backup for another 3 years. i was hoping it would last longer than that!
Shipping was quick and the product was a perfect fit. I would recommend this to anyone who needs to replace their garage door opener battery.
Too soon to know how long it will work as that the critical factor for a battery but it fit the location, was the correct amperage etc. May need to change the review if poor longevity.
Easy, product was perfect replacement, size/fit, for original and is performing like it should. Obviously time will tell all as first battery from liftmaster lasted 4 years.
The battery was very easy to install and was cheaper online than from the company or in the local area. Our power rarely goes out but it is comforting to have the battery backup. I have only had to use it twice but it saved me from getting wet!
The battery was a perfect fit. Easy to install. Arrived on time. Liked the whole process, it's just that &#34;love&#34; is such a strong word. It just say I liked it a lot. 4 and a half stars!! Thanks!
My original backup battery for the 3850 Liftmaster lasted almost 4 years. When I called my garage door/opener company, the owner was very gracious to tell me a replacement would be a snap to install. He was 100% right, the total installation of this replacement took under 5 minutes. I'm also pretty satisfied with 4 year life of the original.
charged right up. It was manufactured recently and it seems in good condition. Old one pulls right out and new one goes right in perfect fit.
Answer: yes
