GTL 26650 12000mAh (White)

Official specifications:

Model: 26650
Type: Rechargeable Li-lithium battery
Capacity: 12000mAh
Voltage: 3.7V
Max Continuous Discharge: 8A
Max Peak Discharge: 4A Peak lower than continuous?
Size: about 66*25*25mm
Colour: White

Super high capacity 26650, again a battery with wrong specifications.

There is significant difference between the two batteries and the capacity is 2000 and 2200mAh at low current. The batteries can handle up to about 7A.

At 7A the A cell get warmest.

At 10A it is the B cell.

Conclusion

These cells where never going to be anywhere near the rated capacity, instead they have less capacity than most other 26650 cells.

I will call them bad cells.

Notes and links

How is the test done and how to read the charts
How is a protected LiIon battery constructed
More about button top and flat top batteries
Compare to 18650 and other batteries

наконец топовый производитель выпустил достойные банки с достаточной ёмкостью.
По сути удалось уместить в 26ой диаметр ёмкость Четырех! 18650
вот она революция в аккумуляторах.
