Husqvarna 400 battery
Install January 2026. I had my misgivings, who wouldn’t? A $30 battery off Amazon I didn’t expect much, I installed in a Husqvarna 400 motorcycle and it fired up right away. So far I’m surprised and happy. Perfect fit, battery came charged, a clean and easy 1 for 1 install.

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.
