## Questions & Answers

**Q: What is the battery capacity in mAh?**
A: Nowhere on the packaging or cells themselves does it state capacity. I have and still do use Sony brand button cells and the quality has been top notch and the prices reasonable. Sony sold their battery business to Murata in 2017. Any stock of Sony brand cells is over 5 years old. Not sure if the Murata cells are as good as the Sony brand cells were but next time I need to restock I will give them a try. Murata CR2450 cells are available just do a search for them.

**Q: The product description on 12/3/2019 says "Expiration Date 2020"?!**
A: I received mine on 11/14/18 and they say use by 2028.

**Q: work on comcast/xfinity window and door sensors**
A: Look at the old battery. If it is a CR2450 it will work. If it isn't, probably not.

**Q: What's the expiration**
A: I bought mine several months ago, and it says use by 2027.
