Charging with a current higher than the recommended value may cause the problem of charge-discharge performance, mechanical performance and safety performance for the battery, and it may cause battery over heat, leakage or flatulence.Charging voltage: Charging voltage must not exceed the rated voltage of 4.2V cell, and 4.25V is the highest limit of charging voltage. The design of charger should meet this condition.When voltage of battery is higher than the rated voltage, the battery may cause the problem of charge-discharge performance, mechanical performance and safety performance for the battery, and it may cause battery over heat, leakage or flatulence.Charging temperature: The battery cell must be charged within the temperature range of 0-40C. Recommended charging temperature is 232C.Reverse charging is prohibited. Connect the positive and negative terminals of the battery correctly. Reverse charging is strictly prohibited. If the battery is reversed, the battery will not be charged. At the same time, reverse charging will reduce the charge-discharge performance and safety performance for the battery, and will cause battery over heat, leakage or flatulence.DischargePrevent over heat, flatulence and prolong battery lifeDischarging current: Discharge current must not exceed the specified maximum discharge current. Large currents will cause the cell
