Performance Specification

4.1 Standard test condition

4.1.1 Standard Charge

Unless otherwise specified, “Standard Charge” shall consist of charging at constant current of 1050mA. The cell shall then be charged at constant voltage of 4.2V while tapering the charge current. Charging shall be terminated when the charging current has tapered to 50mA. For test purposes, charging shall be performed at 23ºC ± 2ºC.

4.1.2 Standard Discharge

“Standard Discharge” shall consist of discharging at a constant current of 420mA to 2.5V. Discharging is to be performed at 23 ºC ± 2 ºC unless otherwise noted (such as capacity versus temperature).

4.1.3 Fast Charge / Discharge condition

Cells shall be charged at constant current of 4000mA to 4.2V with end current of 100mA. Cells shall be discharged at constant current of 10000mA and 20000mA to 2.5V. Cells are to rest 10 minutes after charge and 30 minutes after discharge.

Electrical Specification

Enviromental Specification

Warning:

1.)Do not use different charger. Do not use cigarette jacks (in cars) for charging.
2.) Do not charge with constant current more than maximum charge current.
3.)Do not disassemble or reconstruct the battery.
4.)Do not throw or cause impact.
5.)Do not pierce a hole in the battery with sharp things. (such as nail, knife, pencil or drill, etc.)
6.)Do not use with other batteries or cells.
7.)Do not solder on battery directly.
8.)Do not press the battery with overload in manufacturing process, especially ultrasonic welding.
9.)Do not use old and new cells together for packing.
10.)Do not expose the battery to high heat. (such as fire)
11.)Do not put the battery into a microwave or high pressure container.
12.)Do not use the battery reversed.
13.)Do not connect positive(+) and negative(-) with conductive materials (such as metal, wire)
14.)Do not allow the battery to be immerged in or wetted with water or sea-water.
