Hanaix 7.2 Volt 3500mAh Battery Compatible with Dremel 7700-01 and 7700-02 Replacement 757-01 for Dremel 7.2 Volt Battery (Do not fit for Dremel 770 Type 1)

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

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

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

Perfect fit, worked great.

Perfect! I'm believing this works as long as my original battery of 25 years.

great product

It works fine

Perfect for the dremel. Long lasting battery
