Orbtronic 18650 3100mAh (Black)

Official specifications:

Protected Panasonic 18650 NCR18650A: 3100mAh 3.6V - 3.6V storage charge
Cell: Panasonic NCR18650A - 3100mAh
Typical Capacity: 3100mAh - Discharge:0.2CmA
Minimum Capacity: 2950mAh
Nominal Voltage: 3.6V - 3.7V - ±0.025V
Full Charge voltage: 4.2V
Max. working discharge current: 6.2A - 0ºC to +40ºC
Max. discharge current: 8.5A - 0ºC to +40ºC
Discharge cut-off voltage: 2.5V
PCM Over charge Protection: 4.325 ±0.025V
PCM Over discharge protection: 2.5V ±0.025V
PCM Over current protection: 11A ± 0.3A
Storage Temperature: -20ºC to +60ºC - Less than 1 month
Storage Temperature: -20ºC to +45ºC - Less than 3 months
Weight: 48.5 g - 1.71 oz
Size: 68.9mm(H) * 18.4mm(D)
Bottom plate: Copper
Max charge current: 1C - 3.1A
Recommended charge current: .3C - 0.9A

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.

There is not anything to say about this battery except it is a very good battery.

Notes and links

The batteries was supplied by Orbtronic for review.

How is the test done and how to read the charts
How is a protected LiIon battery constructed

Just another note:
I believe that it will be difficult to get this battery for people that lives outside US, due to the new rules from USPS: No oversea LiIon shipping.

спасибо за обзор!
нашел сразу 2 интересных для меня пункта:
первое: литиевые банки тестируют пятичасовым разрядом
второе: измеренные мной панасоники 3100, купленные в китае
и разряженные 1 ампером в точности соответствуют данной таблице
как по ватт часам так и по ампер часам.
третье: для разнообразия прогоню и остальные режимы, надеюсь тоже совпадут
