1. Charging Charging Current: the charging current shall not exceed 1A. Charging with a higher current than the recommended value may cause problems with the charging and discharging performance, mechanical performance and safety performance of the battery cell, and may lead to heat generation or leakage Charging Voltage: the charging voltage shall not exceed 4.20V. 4.20V is the maximum limit of charging voltage, if the voltage is higher than the rated voltage value, it may cause problems of charging and discharging performance, mechanical performance and safety performance of the battery cell, and may lead to heat generation or leakage Prohibition of Reverse Charging: Connect the positive and negative terminals of the battery correctly, reverse charging is strictly prohibited. If the positive and negative terminals of the battery are reversed, it will not be possible to charge the battery cells. At the same time, reverse charging will reduce the charging and discharging performance and safety of the battery cell, and will lead to heat generation and leakage 2. Discharge The battery shall be discharged at less than 1A. High discharging current may reduce the discharging capacity significantly or cause over-heat It should be noted that the cell would be at over-discharged state by its self-discharge characteristics in case the cell is not used for long time. In order to prevent over-discharging, the cell shall be charged periodically to maintain between 3.7V and 3.9V. Over-discharging may causes loss of cell performance, characteristics, or battery functions 3. Parameters Nominal Voltage: 3.7V Charge Limit Voltage: 4.2V Discharge Cut-off Voltage: 2.75V Standard Charge: 0.5C Standard Discharge: 0.5C Fast Charage: 1.0C Fast Discharage: 1.0C Charging Temperature: 0~+45℃ Discharging Temperature: -20~+60℃ 4. Note The lithium polymer battery should be stored in a cool, dry and well-ventilated place. And should be kept away from fire and high temperature Keep the storage capacity preferably at 30%-50% (at a voltage between 3.7- 3.9V) If the battery has been stored for more than six months or longer, the battery must be recharged Batteries should be stored within the above temperature and humidity ranges Package Content: 2 x 3.7V 3.7Wh 1000mAh Lithium Polymer Batteries
