Official specifications:

• Voltage::3.7V
• Net Weight: 46g
• Size: ø18.4±0.1mm x 68.5±0.5mm
• Battery Capacity:3100mAh
• Cell: Panasoinc lithium cell inside

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.





















Conclusion

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 (But only when tested at the specified conditions).

All in all a very good battery.
