Review: 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.
Review: 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.
