Dell 18650 Cell manufacturer & Capacity?

[OCD]

I just extracted 4 good 18650 cells from a Dell battery pack. Does anyone know who manufactures these cells and what their rated capacity is?



They have have the following numbers printed on them:



LGDA2E18650

529139084xx

DJ02220A2



(xx being sequential numbers)



A did a few searches that turned up nothing.

LGDA2E18650

Based on the label of my pack (type GD761, 11.1V, 53Wh), I would assume 3.7V and around 2350-2400 mAh.

The specs listed on http://bbs.mydigit.cn/simple/?t521353.html for LGDA2E18650 are:

Nominal voltage 3.7V operating voltage of 3V-4.2V
Charging voltage of 4.2V +50 mV cut-off voltage of 2.5V
The charging current MAX 1.8A discharge currents MAX 3A
The following charge cycles the battery internal resistance of 50mΩ 1000
Battery capacity 2600mAh external dimensions of 18 * 65 (W * H) (mm)
