These batteries are not from Panasonic, they are made by an unknown manufacturer that buys Panasonic cells and then add protection!
The cell used can be discharged down to 2.5 volt, in my test I only discharges to 2.8 volt, i.e. I do not measure the full capacity. But then, not all lights will be able to use the full capacity.

The protection circuit trips at a value that will protect the battery from being mistreated.

Conclusion

This battery uses a good cell, this secures many things:

All in all a very good battery.

I have to add a warning to this conclusion: Somebody might see an opportunity to earn more money, i.e. take a cheap cell and add a fake Panasonic wrapper. I expect this will happen!
