ItemMeasuring procedureRequirements
Vibration testAfter standard charge, the battery is to be tested as following Conditions:
Amplitude: 0.19mm
Frequency: 10-55Hz (sweep: 1Hz/min)
Direction: X/Y/Z axis for 30min Battery is to be tested in three mutually perpendicular to each axis
No fire, no explosion, no smoking
Drop testDrop the battery in the shipment condition (full- charge) from 1m height onto 18-20 mm or thicker concrete with p-tile on it 1 times each of obverse and inverse directions at 25±2°CNo fire, no explosion, no smoking
Constant humidity and temperature characteristicsUnder the temperature of 20±5°C, after charging the battery with 0.2C, then put the battery into the constant temperature and humidity oven with 55±2℃ and 90-95% for 48 hours, the battery should be no obvious deformation, leakage, rust, smoking and explosion
After testing take out the battery then rest for 2 hours under the temperature of 20±5°C, discharge with 1C to 3.0V
discharge capacity ≥60% C5
Short circuit testAfter 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 0.1ΩNo explosion, no fire
Temperature of the exterior cell casing shall not exceed 160°C
Heating testBattery is to be heated in a gravity convection or circulating air oven temperature of the oven is to be raised at a rate of 5±2°C/min to a temperature of 130±2°C at which temperature the oven is to remain for 30 minutes before the test is discontinuedNo explosion, no fire
Abnormal charging testAfter standard charge, the battery is subjected to a charging current by connecting it to a dc-power supply Beginning current is 3.0C, which is to be obtained by connecting a resistor of specified size and rating in series with the battery, the voltage of the dc-power supply is 4.6V test time is 2.5 hoursNo explosion, no fire
Overdischarge testFully discharged cell is continually discharged for 24 hours with the (30xn) Ω load at 23±2°CNo explosion, no fire
High temperature characteristics
 
Within 2 hours leave the battery in constant temperature and constant humidity box which temperature is 55±2℃ after fully charge, discharge at 1C to 3.0V Discharge time is required  ≥51 minutesNo deformation and smoking
 
Low temperature characteristics
 
After fully charge, leave the battery in Constant temperature and constant humidity box which temperature is -10±2℃ for 16-24 hours, discharge at 0.2C to 3.0V discharge time is required  ≥3 hoursNo deformation and smoking

 if the above spec can not match with your design, please contact service man for further discussion, he/she will give you our professional suggestion according to your design/intended use. Please kindly offer the below info:

  1. what's your intended use application power in watts?

  2. what's the nominal voltage of your intended use application?

  3. how much max space is for battery container?

  4. how much longer time you want after once full charged on?
