● Do not remove the outer sleeve from a battery pack nor cut into its housing.


世界杯预选赛竞猜● Do not mix our batteries with other battery brands or batteries of a different chemistry such as alkaline and zinc carbon.


世界杯预选赛竞猜● Do not mix new batteries in use with semi-used batteries, over-discharge may occur.

世界杯预选赛竞猜不要将新旧电池混用,  可能会导致过放电.

● Promptly dispose of used batteries in accordance with local regulations.


Ship 运输

世界杯预选赛竞猜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.


世界杯预选赛竞猜解液气味,电解液泄漏等,该电芯不得使用。有电解液泄漏或闻到异常味道的电池应远离火源以 避免着火。

Storage 贮存

The cell shall be stored at the environmental condition of -20℃ - 45℃ and 65%±20% RH. The voltage for long time storage shall be 3.6V-3.9V range. If the cell has to be storied for a long time (Over 3 months), the environmental condition should be: Temperature: 23℃±3℃世界杯预选赛竞猜Humidity: 65%±20%RH;please activate the battery once every 3 months according to the following method: Charge with current 0.2C5A until the voltage achieve to 4.0V.
