Review: Good fit for Gravely ZTX 52 zero turn - Good fit for Gravely ZTX 52 zero turn. Replaced dead 5yr old OEM battery in the spring and has been working great all summer. Doesn't have the slots that were on the top of the OEM battery to hold it in place so I used some foam I had laying around to make a snug fit in the holder. Holes In the terminals are smaller than in the OEM terminals but was not a problem. I just used the nuts and bolts that came with the battery. All a good trade off for a battery a third of the cost of original.
Review: Mighty Max Battery (ML15-12NB / 12V 15Ah - My generator originally takes a 12v 9Ah NB battery. I bought a little larger battery in a Mighty Max Battery ML15-12NB 12V 15Ah. Hoping those extra 6Ah will help my generator start in the harsh Buffalo winters. The battery arrived in a perfect, undamaged box. Opened the box to see another box packed well inside. When I finally got my new battery out, it was larger than I was used to, but extraordinary in all of its glory. Installation wasn't too difficult. Luckily, the battery leads were just long enough to attach properly without any sort or modifications. Well, besides the rubber bungee cord I added to ensure it stayed still. I turned the gas on and pushed the start button. The generator started right up without any issues. Hoping I never have to use it, but if I do, I'm sure my new Mighty Max Battery will work for me just fine. I've purchased Mighty Max batteries before for my jumpstart boxes and have never had any issues. They are GREAT BATTERIES, so I will continue to purchase them whenever a replacement is needed.
