Items Test Conditions Specification

Standard Charge

The "Standard Charge" means charging with constant current 0.2C 5 to3.65V, then charging with constant voltage 3.65V to 0.01C 5 under 28±3 , ℃ charging time will not more than 8h.) (Use Lithium-ion battery charger, which

with an accuracy ±0.05V.

Nominal Capacity

The capacity means the discharge capacity of the cell, which is measured with discharge current 0.2C 5 to cut-off voltage at 2.0V at 28±3℃ rest for 30minutes after the Standard Charge.

Nominal Capacity

≥3400mAh

Cycle Life

After 2000 cycles of charge and discharge, the discharge capacity is measured

with 0.2 C5A discharge current and 2.0V cut-off voltage.

≥80%Nominal Capacity

(Storage Characteristic)

Test the cell initial capacity using 0.2C 5 current at 23±2℃ and record,then charge the cells with 45% capacity, then storage for 3, 6, 12 months respectively at 28±3℃and relative humidity of 45%~75%, then the cell is cycled for 5 times with charge with 0.2C 5and discharge with 0.2C 5 at 28±3℃, The maximum discharge capacity

(longest discharge time) is recorded.)

C2/C1≥85%
The cell is charged and discharged using 0.2C 5 at 28±3℃. The discharge (Capacity Retention
capacity is C1. The cell is stored for 28 days in 28 ±3℃ after fully charged and C2/C1≥85%)
then is discharged using 0.2C 5 at 28±3℃. The capacity is defined as C2.

After the test as C 2 , The cell is charged and discharged using 0.2C 5 at 28± 3℃, The discharge capacity is C3.

Constant Temperature and Humidity

Under the temperature of 23±2℃, after charging the cell with 0.2C 5 ,then put the cell into the constant temperature and humidity oven with 40±2℃and 90~ 95% for 48h,then store the cells at RT for 2hrs, and discharge the cellswith0.2C 5 to 2.0 volts.

The cell should be no deformation, no rust, no leakage, no fire, no smoking and no explosion. Discharge

time ≥3h

Free Fall Test

(The fully charged cell is dropped three times from a height of 1000 mm (the lowest point of the cell) onto a concrete floor. The cells or batteries are dropped so as to obtain impacts in random orientations. After the test, the cell shall be put on rest for a minimum of one hour and then a visual inspection shall be

performed.)
