    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!!

Mighty Max Battery

Replacement for the battery in this. Over the years I've done exactly this a number of times.
Wonderful.
Couldn’t be happier with arrived battery.
Thank you.
So far, the Mighty Max YTX16-BS battery has worked as expected. It arrived from Amazon and delivery was quick. I needed a battery for my 4 wheeler fast and at a better price than Oreilys, Walmart, etc.
Easy to install
Works great as always ...mounted to a generator set up for easy start works just as it should
Placed this order on a Sunday and received it in one day. I was surprised and needed it badly for my atv to get to work on the snow removal also came fully charged. Will definitely be using them again for some of my other rec . vehicles.
Well that was an interesting battery replacement project. 🙂
The Mighty Max battery arrived in great condition and fit perfectly.
(it was a battery replacement for a Stanley FatMax compressor and car starter.)
Love mightymax battery
Came fast and shipped securely
Came fully charged just installed and jamming out
Great service
I have ordered from them before and have had good luck with these batteries for my battery lawn mower.
