|Mechanical performance :|
|Vibration test||After standard charge, the battery is to be tested as following Conditions:|
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 test||Drop 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°C||No fire, no explosion, no smoking|
|Constant humidity and temperature characteristics||Under 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 test||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 0.1Ω||No explosion, no fire|
Temperature of the exterior cell casing shall not exceed 160°C
|Heating test||Battery 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 discontinued||No explosion, no fire|
|Abnormal charging test||After 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 hours||No explosion, no fire|
|Overdischarge test||Fully discharged cell is continually discharged for 24 hours with the (30xn) Ω load at 23±2°C||No 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 minutes||No 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 hours||No 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:
what's your intended use application power in watts?
what's the nominal voltage of your intended use application?
