  1. Rated 5 out of 5

    J n L –

    I have had the 12v 18ah battery that I use for the FM350 gate opener for about 5 years. I have had absolutely no problems with it at all. We get a lot of rain, a lot of humidity and it basically sits in mud for a lot of the year. It’s small for the battery box it is in. I have the conduit running to the house (not solar). One year I found a half inch of rain/water in the bottom of the box but no problems even then. Now the gate opener is another story. We have a 14 foot aluminum gate (super light!) and for 4+ years we have had to give the gate a little tiny lift virtually every single time we open the push gate. It closes fine. The opener’s longevity considering how much the gate slants has been really good, but even though we followed all the installation instructions AND recommendations to the PRECISE, capital, underlined, bolded T!!!, we can’t get the gate to line up with the locking bracket well enough to open every time. The wood beams are in cement so that’s going to be an awful job to replace the beam(s) one day and for how long will it last the next time. so sad. 🙁

Battery arrived intact, on time & even included an extra decal!!! Just the replacement I needed.
First purchase
Arrived in a couple of days and was easy to install. I put it on a charger just to make sure it’s 100% before I take it out for a longer ride.
But it start the Motorcycle So I was able to ride it down my street. It arrived charged, and that was nice. Thanks
Mighty Max ML18-12 18AH Purchased to replace a failed SEL CB17-12 which was original in my HUSKY 400 Jump Starter (Model HSK0012HD). New battery purchased at Amazon was charged at 12.9VDC when it arrived and exact dimensions for a perfect fit. Quality of the new battery is excellent and has given life to my jump starter. Will be using a battery tender smart float charger going forward to extend the life and capacity of this new battery.
Great fit for my generac standby generator!!
10/10 product, super strong battery that last honestly forever, and it is super fast, I used it on a 420cc predator and on the first crank it started right up.
