Great battery
This fits perfectly to the cordless model and has a lot of power . Very light and durable . Because it holds a lot of charge, it functions good and the value is well priced. You do have to charge it before using but overall it is a good battery

Great 2nd Battery to Allow You to Keep Working
Great battery, same durability as the one that came included with my Dremel tool. I just needed a second battery to allow me to continue working while the used one recharges.

Expensive for a small battery but it works great
I needed an extra battery and I saw this one. While there are knock-offs I wanted a real Dremel battery since my unit is pretty new. The only issue; this thing is EXPENSIVE

Higher capacity than the battery packaged with my Cordless Dremel rotary tool
I purchased this battery as spare for my cordless Dremel Rotary Tool. The original battery with the tool is a 2ah. This one is a 3ah. It shipped half charged, and charged up on the Dremel charger in about 20 minutes. Fits as expected, and it is no larger than the original battery. Power to the cordless tool lasted longer than I expected, carving and cutting. at $57 I feel it was a little expensive. I am satisfied with the purchase.

Needed a spare for out in the field
each battery does 3 chains 20" Add a filer tool and you are set for chainsaw sharpening with a dremel bit the right size.

It's a Dremel battery, so it works with my Dremel tool. Way too expensive, but I've read too many bad things about various knock-off batteries. If you want a spare battery, this one works. I have found these Dremel batteries to be extraordinarily difficult to remove from the tool. The YouTube videos must all be done by Arnie or some other well-muscled young man. I filed down the little catches on the battery A LITTLE and I can now remove it without big pliers. Other than that it's just fine. It's only two weeks old so I can't comment on durability.
