    This backup battery is a perfect fit for my garage door opener which is a Liftmaster model 3850p. It is the same size as the original backup battery (485LM) and fits perfectly in the slot. Super easy to replace/install. This is a much cheaper price then getting an OEM replacement (485LM). Works great!!

Excellent
Mighty Max Battery
Based on 4336 reviews
Battery came in a very secure carton from the manufacturer. I have purchased (3)car batteries from Mighty Max, 2 for my wife’s Grand Cherokee, one main and 1 auxiliary. And the other one for an Equinox, and have had great results with them. I haven’t installed this one in my lawn tractor yet, but have no reason to think it wouldn’t be just as good as the ones I already have!
Great Company to deal with !
Can't speak to the quality or longevity of this new battery because we just bought it, however, the previous one only lasted about 3 years. Got this one on Zoro.com for around $315. Just writing this review for the extra 3 months. Left 3 star rating, one star for each extra month of warranty. Buying reviews seems wild but whatever. Buy at your own risk. I don't endorse or oppose this product. We use it in our semi-electric straddle stacker from uline.
Still in box will update after a few weeks of being installed.
Generator started right up. Battery had strong charge out of the box.
Just got, packed safely and secure, haven’t installed yet
Looks like it will fit my application. Picture of doing a full charge before I put it to use. Using this in my Honda EU3000is inverter generator.
Fit fine ! Battery back up useful again.
An amazing battery for the price! Started my machine right up!
Great and powerful
