Test/Review of AW 18650 3100mAh (Black)

AW 18650 3100mAh (Black)

Official specifications:

Nominal Voltage : 3.6V
Capacity : 3100mAH ( rated at 0.2C discharge 4.2V - 2.5V @ 25° )
Operating Temp. : Charge 0 to 45° / Discharge -20 to 60 °
Recommended Charge Rate : max. 2170mA ( 0.7C ) - ambient temp. 25 °
Max. Discharge Rate : 6.2A ( ambient temp. 25 ° )
Dimensions :18.50 X 68.16mm ( +/- 0.3mm )

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.

AW ships the batteries in a small box.

These batteries are real flattop batteries, i.e. the plus pole might not connect when pressed against a flat surface. This will usual prevent the batteries from being used in series (because the minus pole is a flat surface on most batteries), but because the minus pole on these batteries has 3 bumps, they work fine in series applications.

These batteries are slightly lower in capacity, compare to some other batteries with the same cell, this might due to a different production batch or the cells being slightly older.

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).

The battery is one of the shorter 18650 batteries, but it is a flat top battery. The first can be an advantage, the last can be a disadvantage, depending on equipment.
All in all a very good battery.

И все же нету там 3100, но все равно отлично. Жаль цена кусается

That is only part of the answer, the other part is the charging cutoff current, where I uses 100mA, but the data sheet says 60mA.

The full data sheet is here: http://industrial.panasonic...

I will test some cheaper batteries based on the NCR18650A later on.

Is it 'International Outdoor' one?

That is one of them, there is also another candidate, but I do not have the price yet.

I believe that it will be 6 different batteries with the NCR18650A cell I am going to test.

Блин, ну нахера в AW сделали утопленный плюсовой контакт? Зарядка Икстар не контачит, ТМ11 не контачит, у Зебры Н600 крышка со скрежетом закручивается из-за пупырышков на минусе. Надо было Редиласты брать.

Да она как-то через раз. То контачит, то нет.
