Chamberlain Liftmaster 485LM Battery LiftMaster Garage Door Openers 485LM Battery Backup, OEM

Great battery. Installed it and everything works great. Much cheaper than the other places on Amazon.

Fit perfectly and was easy to install. Last battery lasted for 6 years. I hope this one lasts as long.

Clear description was provided. Received as was indicated and next day. No issues or concerns.

Purchases replacement battery for garage door. Easy to install

So far so good. Just installed it and it charged up and it’s working fine. Will have to wait and see how long it lasts. Got 6 years out of the original.

The battery arrived on time. When checking the manufacturing date on the box I learned that the battery is already 9 months old. Not happy about this as it raises questions on longevity; however, when buying the battery I also purchased the 2 year protection plan. The installation was easy. I was hoping the box would provide suggestions on how to dispose of the old battery but it did not. The battery is working but I am not in the position of weighing in on longevity or value for money although I do feel the purchase price was a bit much.

Arrived quickly and just as described.

This is battery was a perfect replacement for the original Liftmaster battery which was inoperable after about 5 years, the expected time of its demise. It looked new, even if its manufacture date was about a year old which is no problem for a lead battery that has not seen any service, and it was in a Liftmaster box, with labelling on the battery which looked exactly like the original. Both are made in China, and it seems either original or made by the same company that sells directly to Lifemaster. Of course, since I just installed it, I can't comment on duration of life, but its surface voltage was correct, and it operates the door without problem with the AC disconnected from the motor. The battery was shipped promptly and came in good time, properly packaged. Based on service rates where I live, between the call and the extra markup on the battery if you buy it through dealers or servicemen, you'll probably save $150-$200 to do it yourself which is an absolute snap. I think any one of my five cats could have done it: Just remove one Phillips screw, pull the battery half out, disconnect the terminals, insert new battery halfway in the housing, reconnect the terminals, which are size coded to you can't get it wrongly, and push the battery home, close the door and reinsert the single screw. It takes all of a few minutes tops. Because this is a low voltage circuit, you don't need to turn off the power, and you are in no proximity to high voltage wiring. After you have successfully installed the battery, the low voltage beeping should go away, and you should have no more orange or red warning lights on the chassis. After you have had the battery in service for 24 hours, disconnect the motor by pulling out the AC power cord, simulating a power failure, and run the door up and down a couple of times to be sure that the battery is working properly with a load BEFORE you throw the shipping box away. BOTTOM LINE: ENTHUSIASTICALLY RECOMMENDED WITHOUT RESERVATION.

Exactement ce qu'il me fallait. Excellent. Et vraiment pas dispendieux.

very nice works great , great price, looked just like the original one we took out.

Easy installation. Product arrived as I expected.

La batterie que j’ai reçu est étiquetée comme ayant été fabriquée en 2017, elle a été très longue à recharger par mon ouvre-porte (environ 72 heures), néanmoins elle fonctionne bien. On verra a l’usage combien de temps elle durera. J’ai conservée l’original pendant 7 ans.
