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.
This battery uses a good cell, this secures many things:
- The batteries does match in capacity, i.e. they can be used in series.
- The battery is very safe.
- The battery has the specified capacity.
There is not anything to say about this battery except it is a very good battery.
