How to charge the lithium battery correctly

by：Vglory 2021-03-24

Lithium battery equipment is usually charged at a normal charging rate for 7 hours. If necessary, a decreasing charging method can be used, that is, charging at twice the normal charging rate for 2.5 hours, and then charging at the rated charging rate for 2 hours. During charging, you must pay attention to the temperature of the battery. Regarding the electrolyte without grade oxidation, its temperature shall not exceed 30°C. The temperature of the electrolyte added to the hydrogenated steamed bun is allowed to be higher than 30°C but not to exceed 40°C. When the temperature is too high, the charging should be stopped, and the charging should be performed after cooling. It is best not to remove the plug when charging, otherwise carbon dioxide will enter the battery and easily cause the electrolyte to fail. When gas is generated in the battery, the plug will make a hissing sound. Pay attention to check that the rubber sleeve of the stockade has good elasticity, otherwise the internal gas cannot escape, which will cause the casing to expand. For lithium battery equipment, the degree of charging cannot be judged by measuring the specific gravity or by the occurrence of bubbles in the electrolyte. The correct way to judge is to observe the voltage of the two poles. If the voltage of the lithium battery device rises to 1.8 volts, if there is no significant change in the voltage after one hour, and the charging basin has reached 140% of the discharged power, the charging is considered to be finished.
