Mighty Mule 12-Volt Battery for Mighty Mule Automatic Gate Openers (FM150) , Black

This battery has been an absolute workhorse for our gate system. In a high-traffic setting with over 40 open-and-close cycles per day, it has never failed us—not even once. That kind of reliability is hard to come by, especially for something that lives outside and handles constant use.Installation was simple and straightforward, and it’s compatible right out of the box with our Mighty Mule setup. It's clear that this battery was built specifically for the demands of an automatic gate, and it shows in the way it holds a charge and performs consistently.Living in a rural area where dependable access is critical, this battery has become an essential part of our day-to-day routine. No slowdowns, no surprises, just solid power you can count on every single day.

Bought this battery to power my old (and now discontinued) Mighty Mule MM260. Previously powered it with an old car battery for a few years but it finally kicked the bucket. So far no issues, but we will see how long it'll last. I do like the size and weight as it'll be easy to seal inside a container away from the weather.

Good battery replacement to supplement power to gate. It fit exactly into the case next to the other batter. It was easy to install and cost was reasonable.

Old battery was a few years old and was only opening one side of the gate. New battery instantly solved the problem.

Got a generic battery with my order. It was the proper specs and works, but not sure it's worth extra for a "Mighty Mule" battery.Complicated by the fact you don't know if it's Amazon's fault, Mighty Mule's fault, Mighty Mule's distributer's fault, or a sneaky customer that returned it. I'll update if the battery explodes and blows up my MM372 setup.

Have had trouble with the gate opens by itself a lot

We had to replace the battery on our MM560 gate opener in early 2020. I happened to have a compatible 7AH 12V Sealed Lead Acid (SLA) battery in my office (I use it for my fish finder), so we used that. Mighty Mule says to ONLY use "genuine" GTO replacement parts, so I bought a GTO (Mighty Mule) branded battery at almost 1/3 more than other brands, and then swapped them out. The "new" battery ran OK for about 6 months, before I had to replace it again. I put the battery from my office, a ChromeBattery, back in the gate controller and it continued to work flawlessly for 2.5 years. After we had an issue with the opener, I decided to replace it with a Ghost - the Ghost requires TWO 12v batteries to operate. The ChromeBattery was drained. I decided to deep-cycle all three - the Chrome as well as BOTH GTO batteries (the original, plus this replacement that I purchased), and the only one that came back to life was the Chrome. So I bought two more at HALF the price, and they are both working just fine. DO NOT BUY - the GTO branded battery is overpriced garbage. Along with everything else they sell.

Fit as should works as should will see how it holds up over time
