This battery uses a new version of the Panasonic 2900 mAh cell designed for higher current.
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 voltage and capacity at higher current is slighty higher then the old 2900 mAh cell (Use my comperator to compare).
The two batteries I got does show a very good match.
