## Questions & Answers

**Q: Can I charge it with 220 V??**
A: Don't think so. Charging calls for 110v in the charger (US) Would check voltage requirement.

**Q: Is this a good replacement for dremel B814-01?**
A: I is a great replacement for my Dremel battery pack No. 855-02.

**Q: Is this compatible with Dremel model 8260?**
A: I have the Dremel model 8260. This battery does NOT work in this model of Dremel. It fits the charger ok and seems to charge alright but the tool absolutely will not turn on with this battery installed and charged. The info on the original battery lists the battery # as B816-01. That is not the # listed on this Hanaix.

**Q: does this work with Dremel 8250 tool?**
A: This battery works great for the Dremel 8220 that I have. You might want to check their website and ask if its compatible with the 8250. From what I've seen it won't work. Hope this helps
