This is the latest cells from Panasonic with the highest capacity. 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.
These batteries are good at both low and higher current.
These are unprotected cell, i.e. the protection will not trip.
