3. Performance And Test Conditions
3.1 Standard Test Conditions（标准测试条件）
Test should be conducted with new batteries within one week after shipment from our factory and the batteries shall
not be cycled more than five times before the test. Unless otherwise specified, test and measurement shall be done
under temperature of 20±5℃ and relative humidity of 45~85%. If it is judged that the test results are not affected by
such conditions, the tests may be conducted at temperature 15~30℃ and humidity 25~85%RH.
3.2 Measuring Instrument or Apparatus
3.2.1 Dimension Measuring Instrument
The dimension measurement shall be implemented by instruments with equal or more precision scale of 0.01mm.
3.2.2 Voltmeter
Standard class specified in the national standard or more sensitive class having inner impedance more than 10kΩ/V
3.2.3 Ammeter
Standard class specified in the national standard or more sensitive class. Total external resistance including
ammeter and wire is less than 0.01Ω.
3.2.4 Impedance Meter
Impedance shall be measured by a sinusoidal alternating current method (1kHz LCR meter).
3.3 Standard Charge/Discharge
3.3.1 Standard Charge : 0.2C
Charging shall consist of charging at a 0.2C constant current rate until the battery reaches 4.2V/cell. The battery
shall then be charged at constant voltage of 4.2V/cell while tapering the charge current. Charging shall be
terminated when the charging current has tapered to 0.05 C
5
A. Charge time: Approx 7h, The battery shall
demonstrate no permanent degradation when charged between 0 ºC and 45 ºC.
3.3.2 Standard Discharge : 0.2C
Battery shall be discharged at a constant current of 0.2C to 2.75V/cell @ 20º

5C
3.3.3 If no otherwise specified, the rest time between charging and discharging is 30min.
3.4 Appearance
There shall be no such defect as crack, rust, leakage, which may adversely affect commercial value of battery.
4. Handling of battery
4.1 Prohibition short circuit
Never short circuit battery. It generates very high current which causes heating of the battery and may cause
electrolyte leakage, gassing or explosion that is very dangerous.
The poles may be easily short-circuited by putting them on conductive surface.
Such outer short circuit may lead to heat generation and damage of the battery.
An appropriate circuitry with PCM shall be employed to protect accidental short circuit of the battery pack.
4.2.Mechanical shock
Falling, hitting, bending, etc. may cause degradation of battery characteristics.
5. Others
Prevention of short circuit within a battery pack
Enough insulation layers between wiring and the cells shall be used to maintain extra safety protection.
The battery pack shall be structured with no short circuit internally, which may cause generation of smoke or
firing.
