Panasonic Lithium Power CR123


Official specifications:

• Nominal voltage (V): 3
• Nominal capacity (mAh): 1550
• Continuous standard load (mA): 20
• Operating temperature (C): -40 ~ +70

A small battery that can deliver a lot of energy.











The battery starts at 3.2 volt when new, when loaded the working voltage is closer to 2.5 volt.
Notice the strange discharge curve at 3A, this is probably because the PTC in the battery got hot and disabled it.










Conclusion

This is the first CR123 I test, making it impossible to comment on performance, except saying that this small battery size packs a lot of power.
