    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 3870 reviews
Fast ship, sturdy packaging. Great fit, brought booster pack back to life.
Delivery was prompt and the packaging is outstanding. This battery starts my Westinghouse generator quickly. I have a few and I like them over the OEM batteries.
Next day arrived. Easy to install.
Used in my wood chipper
Gel battery for my Kawasaki Mule
Ordered a 3-pack of 12v 10ah batteries for my Black and Decker lawn mower. Batteries were a perfect size replacement, requiring no modification to the housing. Fully charged and ready to go.
Battery works great
I originally ordered the wrong battery. I asked to cancel the item and expected a hard time…. I was very nicely informed that my incorrect order was cancelled.
Then I ordered the correct battery ( pretty late in the day). I expected delivery to be at least 2 days . It was delivered in less than 24 hours. Great customer service and fast delivery. It was a nice experience, I would recommend Mighty Max Battery to anyone looking for a battery….. forgot to mention the great price, too.
The battery is a perfect fit. Here is a picture of it in the HONDA generator it now calls home.
Quick delivery
Arrived quickly charged. Working fine so far
