### ⭐⭐⭐⭐⭐ Effectively powers a Dremel 8200
*by A***R on March 21, 2025*

Dremel 8200- Battery fit well into charger and charged fully (in maybe an hour or two).- Battery was easy to remove from the charger- Battery fit in to the Dremel body without issue- Unit seems to run well with this battery. 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*

### ⭐⭐⭐⭐⭐ Great replacement or back up battery
*by M***E on June 6, 2025*

Battery uses factory charger great as a replacement or spare. I use for my dremel
