It works. For a little while (if you don't mind recharging rather soon)
It does not hold a charge for very long.
Yes, it holds charges for longer than the batteries I've owned for years. However, I get only 50-70 board feet out of this before it slows. My old ones would get at least 300 board feet.
For a lower price, these would be worth it. However, after charging and draining this battery three times rather quickly in my track saw, I switched back to using my circular saw with my track.
