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

Replaced original battery
Easy to install and works as expected.

AAA Security Depot
Gonna indicate that I purchased this battery from AAA Security Depot as Amazon lumps all reviews for this same product from different vendors/sellers. Product was genuine OEM and exactly as file photo showed down to the box. Ordered the battery in 1/3/24 and the battery manufacture date was 12/23, literally only one month old and fresh! Great price and fast shipping to Hawaii. Definitely recommend this product and seller.

Direct replacement battery
I was disappointed when the battery came only half charged, but I installed it anyway, and within 6 hours it was fully charged and working fine. Has not lost charge yet, extremely easy to replace.

Works perfectly well.
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.

muy bien parte original y rápido el envio . . . . . . . . . . . . .

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.
