## Questions & Answers

**Q: Can the same charger be used for both rechargeable 2032 and 2450 batteries?**
A: I think so.  I found that the rechargeable batteries really just don't last long enough to make them worth while.

**Q: why is the voltage higher than typical for this battery type (3v vs 3.7)?**
A: Because it uses a different chemistry than the non rechargeable coin cell batteries.  The voltage of a battery is dictated by its chemical content. If they had used nickel cadmium for example, the voltage would have been 1.2v.

### ⭐⭐⭐⭐ Easy recharge
*by W***8 on 19 January 2023*

Great that you can recharge 2450 batteries, which you would not expect. Rechargeable batteries don't last as long as the non rechargeable ones when in use. I'm having to recharge them every 3-4 weeks, whereas non rechargeable lasted 2-3 months in the same device. Would like to see rechargeable batteries with higher capacity, but overall, still saves cost on buying new batteries all the time.
