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 battery is packed both in a box and in shrink wrap.
Very nice tracking between the two batteries.
This battery has higher capacity and better high current capacity than its predecessor (3100mAh/NCR18650A).
With the added protection it is a very good battery.
