### ⭐⭐⭐⭐⭐ Solid Replacement
*by K***K on January 7, 2026*

Replacement battery for Dremel 7700-01 tool fits perfect and works well. Good value.

### ⭐⭐⭐⭐⭐ Excellent product
*by L***H on December 25, 2025*

This battery works fine and a perfect fit for my dremel.

### ⭐⭐⭐⭐ A so so replacement for Dremel battery
*by J***. on August 26, 2025*

I needed to replace my Dremel battery and saw this one. Seemed pretty good. I charged it and put it in and it was powerful. The only issue is the clips to hold it on the tool aren't molded exactly like the original. They don't hold it real secure. So it may come lose while using. Not a huge deal. I did some filing of the tabs and it works a little better. Not perfect, but usable for what I use it for
