The battery works great and holds a charge for a good amount of time but... it doesn't fit snuglyl in the charger which I find irritating.  It wobbles a bit and you have to be sure the contacts are touching then make sure it's somewhere where it won't get bumped.  Other than that, it's fine.  You should know that the Paslode Framing nail gun I am using is an older model purchased around 2005.  My guess is that it will fit fine in the newer chargers, but I haven't checked that out.
