INR18650-3000mAh Li-ion Rechargeable cylindrical battery, 18650 battery, High security lithium ion battery, power tool lithium ion battery supplier Environment Adaptation Performance for 18650 lithium ion battery supplier NO Item Standard Test Method 1 Altitude/Low pressure simulation test no leakage, no fire, no explosion The full charged cells are to be stored for 6h at an vaccum environment with pressure of less than 11.6kPa and atemperature of 23℃±3℃.
2 Free drop test no fire, no explosion The fully charged battery drops on the concrete ground from height(1m), total 3 times, to obtain the shock of random directions.
3 Vibration test No remarkable damage、No smoking 、No explosion After standard charging, fixed the cell to vibration table and subjected to vibration cycling that the frequency is to be varied at the rate of 1Hz per minute between 10Hz and 55Hz, the excursion of the vibration is 1.52mm. The cell shall be vibrated for 90 minutes per axis of x, y axes Storage Temperature for Shipping If the cell is kept as ex-factory status (50% of charge), the 0.2C recoverable capacity rate is more than 90%.
1 month -20°C ~ 60 °C
2 months-20°C ~ 40 °C
3 months-20℃~ 25 °C ● When use the battery, must to ensure the charge and discharge voltage of the battery is between 2.75V to 4.2V.
● Do not remove the outer sleeve from a battery pack nor cut into its housing.
● Do not mix our batteries with other battery brands or batteries of a different chemistry such as alkaline and zinc carbon.
● Do not mix new batteries in use with semi-used batteries, over-discharge may occur.
● Promptly dispose of used batteries in accordance with local regulations. Ship The cells might be damaged during shipping by shock. If any abnormal features of the cells are found such as deformation of the cell package, smelling of an electrolyte, an electrolyte leakage and others, the cells shall never be used any more. The Cells with a smell of the electrolyte or a leakage shall be placed away from fire to avoid firing. Storage of power tool 18650 battery
The cell shall be stored at the environmental condition of -20℃- 45℃ and 65%±20% RH. The voltage for long time storage shall be 3.5V-3.7V range.
