No	Project	Standard	Testingmethod
1	Cycleperformance	Noexploding, No fire	After standard charged,keep the battery for 48hrs under75 °C, then rest for 6hrs under -20 °C,then rest for 24h under normaltemperature, discharge with 0.2C5A to32.0V.with1C/1C cycle for 3 times.
2	invariableness moist heat performance	Discharge capacity / standardcapacity×100%>60% Noexploding, No fire	After standard charged,keep in constant temperature andhumidity case for 168hrs under 40±5°C,relative humidity95%, thenrest for 2h, discharge with 0.2C5A to32.0V.
3	Dischargeperformance in different temperature	Discharge capacity /Rated capacity×100% (A)60 °C ≥95%; (B)0 °C ≥85%; (C)-10 °C≥45% Noexploding, No fire	After standard charged,constant temperature rest fro3hrs in 60±2°C, discharge with 0.2C5A to32.0V, standard charge in normaltemperature, separated rest for 20hrs in order 0±2°C/-10±2 °C, test the last capacity with0.2C5A, Then rest 2h in the normaltemperature.
4	Vibrationenvironment adaptive performance	Rest capacity ≥originalcapacity*95% Voltage reducingrate≤0.5% Impedance increasing rate≤20% Noexploding, No fire	After standard charged,build battery in the vibrationtable-board, according to vibration frequency and relativemoving to adjust the test equipment, from X,Y,Z three aspects, every aspectwith 10Hz~55Hz cycles vibrate for30min, thespeed is1oct/min: (A)Vibrationfrequency:10Hz~30Hz Moving:0.38mm (B) Vibrationfrequency:30Hz~55Hz   Moving:0.19mm. After test,0.2C/0.2C test the rest capacity

 

 

 

Notice

 

In order to prevent the battery leaking,getting hot and exploding, please pay attention to preventingmeasure as following:

 

Warnings!

 

• Never throwthe battery into water, keep it under dry, shady and coolcircumstance when not use.
• Never keepthe battery beside high temperature source examples: fire, heatingmachine and ect.
• Please usethe stated charger when charging.
• Never upsidedown the positive and negative.
• Never cutthe battery in socket directly
• Never throwthe battery into fire or heating machine.
• Neverconnect the positive and negative of battery withmetal.
• Never shipor store the battery together with metal
• Never knock,throw or trample the battery.
• Never cut through the battery with nail orother edge tool.
• Never use or keep the battery under the hightemperature. Otherwise it will cause battery heat, get into fire orlose some function and reduce the life.
• Never use the battery under strong static andstrong magnetic field, otherwise it will destroy the protectingdevice.
• If battery leaked, the electrolyte get intoeyes, please don’t knead, please wash eyes by water and send tohospital. Otherwise it will hurt eyes.
• If battery emit peculiar smell, heating,distortion or appear any unconventionality during using, storage orcharging process, please take it out from device or charge and stopusing.
• If the pole was duty, please clear it beforeusing.
• Please encase the pole with isolative paperwhen you want to abandon the battery to prevent exploding andgetting into fire.
