Good for throwing clays
I use this for a Champion Workhorse clay thrower without the wobbler. It came charged, but I put it on my charger anyways, and it turned off almost immediately. I have no clue how many clays it will throw, but me and my brother threw at least 100 clays, and when I got home and put it on my charger, it was fully charged in about 1 minute. I probably could have gotten an even smaller battery, and been just fine.

Fits Predator Generator
Installed it in Predator 8750 generator, it's a little shorter but original battery hold down fit perfect. Battery is strong for its size and no problem spinning generator engine. Saved $25 bucks over HF and would recommend this battery.

Perfect size & perfect power!
Good lil battery! This is exactly the type I needed for my Honda shadow. Super easy install. Charges in no time at all and has the perfect amount of power nessecary for all components and assesories. I have extra lights, phone charger and speakers and this runs them all! It also fits like a glove! Great product and great price!

Very Capable Battery
Fit on my Harbor Freight Predator 8500 generator and wired up in minutes. The only slight drawback is that this battery is about an inch shorter so the battery holddowns are a bit more trouble to tighten. It still moves around a little bit but added a couple zip-ties to keep it in place. So far so good, fires right up on the electric start and has stayed charged but it's only been a few months. Would buy this again!

Thank you for producing inexpensive batteries for us to use
This is a perfect replacement for a yard tractor. My other battery was 12v at 7.2Ah and had 130 CCA. This one works and keeps working.

I refreshed all my atv batteries with Mighty Max. one of them was bad. Contacted the company and had a replacement out the next day. Thats the measure of a company - how they treat you once they have your money. The company was great. The batteries are working great in my atv's snowmobiles and lawn tractors.

Lo compré para mi vento 300 sportivo y funciona muy bien.

Came fully charged and fit perfectly. It was a little difficult to place the "nut" high enough within the post cavity for the screw to start and grab the thread, but I solved it by adding a small piece of electrical tape beneath the nut to rise it up a little.
