Performance

3.1 Standard Test Conditions

If not specified, the test shall be 25%-85% of the environment ,carried out at 20±5℃humidity ,the humidity is too much will effect on the accuracy of test results, the test must be used for no more than a new battery after shipment from our factory,and the cells not be cycled more than 5 times before the test .

3.2 Measuring Instrument or Apparatus

3.2.1 Dimension Measuring Instrument. Accuracy of 0.01mm caliper range is 0-200mm

3.2.2 Voltmeter and Ammeter.

Voltmeter accuracy of ±5mV, range is 0-20V; Ammeter accuracy of present current ±(0.3%±30mA)

3.3 Nominal Charged Test Conditions

At20±5℃,the testing process that standards as follows: first 0.5 C₅A constant battery charge to 4.20V,when the charge current decreases, then charged to 4.20V constant currect is reduced to 0.02C₅A,the charging time is about 3 hours.

3.4 Nominal Discharged Test Conditions

At20±5℃,battery constant discharge to 3.0V,Unless otherwise defined, 30min, rest period after charge,30min,rest period after discharge.

3.5 Battery Performance Test

No	Item	Standard	Test Conditions	Test Ways
1	Leakage Test	No leakage	Typical full charged new battery	Standard charge condition,full charge after 60±5℃temperature, humidity 60±10%RH storage one month.
2	Vibration Test	80%	Discharge Temperature
3	Drop Test	100%	23℃ Discharge Temperature	After standard charge, the battery is to be tested as following conditions: Amplitude:1.6mm Frequency:10~55Hz(sweep:1Hz/min) Direction: X/Y/Z axis for 30min. The battery is to be tested in three mutually perpendicular to each axis.
		95%	45℃
		≥90%	2C Dicharge
		No electrolyte leakage, smoke	Typical full charged new battery
		No electrolyte leakage, smoke or explosion	Typical full charged new battery	Drop the battery in the shipment condition(full- charge)from 1m height onto thicker concrete with p-tile on it 2 times each of obverse.
4	Squeeze Test	No electrolyte leakage, smoke	Typical full charged new battery	Battery placed between two flat metal plate ,applied 13KN（1.72Mpa） force,and continued for 30 min.
5	Short-Circuit Test	No explosion,no fire.The temperature of the exterior cell casing shall not exceed 150℃	Typical full charged new battery	At normal temperature about 25±5℃，After standard charge, the battery is to be short-circuited by connecting the positive and negative terminals of the battery with copper wire having a maximum resistance load of ＜10mΩ.
6	Impact Test	No fire, no explosion	Typical full charged new battery	The battery to be fully charged with standard charging condition, and put a rod with diameter 56mm on the cell, and then heavy block (weight 10Kg) crash on the cell from a certain height(height=100cm).
7	Over-discharge Test	No fire, no explosion	Typical full charged new battery	The fully discharged cell is continually discharged for 2.5hours with 1 C₅A current.
8	Prick Test	No fire, no explosion	Typical full charged new battery	The full charged battery with a needle φ3mm at speed 10-40mm/s from perpendicular to the battery plates through (needle stays in the battery)
