I haven't completely discharged it yet, but it's working great thus far.- Note: It was difficult to remove the battery from the unit on the first go. I had to gently use a pair of channel locks to get sufficient grip, but it has loosened up to the point where I can remove it by hand now with a little effort.- All-in-all, I'm giving this device 5 stars because it effectively powers my Dremel 8200, and Dremel no longer makes a battery for this model (I called them). ### ⭐⭐⭐⭐⭐ Shockingly good *by R***B on June 5, 2025* Works great and allowed me to find my mussing original within minutes of opening box.... ### ⭐⭐⭐⭐⭐ Great replacement or back up battery *by M***E on June 6, 2025* Battery uses factory charger great as a replacement or spare.
