## Questions & Answers

**Q: Will this work with an older model ti-nspire cx calculator?**
A: Yes, It worked with model ti-nspire cx

**Q: Can battery replace calculator battery 3.7l1060sp 3.7v 1060mah 3.92wh in a ti-nspire cx?**
A: I don't know if they are interchangeable. Sorry.

**Q: wil this work with the old version of the ti-nspire cx. The old battery was a bit smaller.**
A: Yes. I ordered this for my ti-nspire cx and this battery was actually small enough that it fit a little loosely in the battery slot, (not so loose that it'll shake around inside though) but the 4-pin connector still fit and mine works like new. As long as you have the connector plugged in it should work fine despite the battery size.

**Q: The plug isn't the same as the original battery?**
A: It matched the plug for my 2011 TI Nspire CX
