Question: I read mixed reviews regarding if this is a genuine liftmaster battery as supplied by chamberlain.  Is it or not?
Document: Works fine but it does not say Chamberlain on it and I suspect it is not a genuine Liftmaster battery which is what I thought I was buying. I was disappointed because as you can see it looks in the picture like a genuine manufacturer's part
Description and image mislead me to believe I was getting original Chamberlain Liftmaster Brand. Instead I received some generic brand which I could have gotten else where for less. Disappointed.
iI enjoy this product and it is working fine. I would recommend this liftmaster 485 LM battery to anyone.thanks
It seems that either battery is bad or was not charged fully. I have to purchase another one (which I am buying directly from LiftMaster). Very disappointed.
I used this ion a liftmaster 3840P and even though the site advertises this to be only for the 3850, it works. It is also the model suggested by liftmaster (485L). The battery however is NOT a true liftmaster battery but rather a clone.
We recently replaced our old clunky Sears garage door opener with a Liftmaster opener. While the opener had the ability to operate sans commercial power, we had not purchased the attendant battery. This provided an affordable battery to that end. I am happy.
It had been 5 years since I bought my liftmaster garage door opener, so it was time for a new battery. This one slipped in and after charging has worked fine during one power outage so far. Should still get my 10 uses on the battery.
Liftmaster brand battery, easy to install and half the price through Amazon vs. the Liftmaster website and shipping was free. The local Liftmaster installation companies wouldn't sell me the battery without installing it for an additional fee. I am very pleased I found it on Amazon. Installation takes minutes if you have phillips screwdrive and a step stool.
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.
I paid at least $20 extra to obtain the LiftMaster OEM battery from CBC Manufacturing and Supply. The product I received, however, was an off-brand battery manufactured in China. I could have purchased the off-brand for much less on Amazon. I purchased the same battery in April, 2013 from Accessories Direct.com and that battery WAS a LiftMaster OEM battery.
