Rated 5 out of 5 by Works great thus far I've had the battery for about a month now and is powering my gate just fine. About the cheapest battery you can find and is small enough to hide in a weatherproof junction box. Must buy terminal connectors for the power wires though. The battery does not have nut and bolt connections. Battery is located in bottom right corner in weatherproof junction box in attached picture. I also purchased the Mighty Mule gate opener from Home Depot which is working great as well! April 22, 2014
Rated 1 out of 5 by Not sure what its for? Bought it thinking it was what powered the gate opener. Then the video and instructions show a marine battery. The size of a car battery, not a lawn mower battery. August 5, 2014
Rated 5 out of 5 by 12 Volt Battery for Gate Opener The battery was necessary to run my alarm system. It works perfectly. June 17, 2014
