## Questions & Answers

**Q: What rechargeable battery brand/model fits the flex belt controller? Need exact/correct recommendations. Thanks.**
A: This battery works: Kastar Cordless Phone Battery for V Tech 89-1323-00-00 80-1323-00-00 80-0099-00-00 8900990000 27910 Vtech . The plug that hooks in to the controller will need to be slightly sanded so it has 2 round corners rather than all square corners but I replaced all my old batteries with these batteries and they work great. See link for battery for pictures.

**Q: I am needing just the piece that plugs into the wall.  Do you sell that**
A: Yes, it's available on TheFlexBelt.com and it's under Accessories, and it's called 'Replacement Charger Only'.

**Q: ICan I buy the charger separately from the controller of flex belt**
A: Yes, only on the Slendertone website (it works with Slendertone or Flex Belt).

**Q: I just need the charger for the Flex belt, where can I get one?**
A: You can buy it on the Slendertone website (they make Flex Belt) for $20.
