Charge of Lithium battery: according to the structural characteristics of Lithium Battery Replacement,lithium battery, the maximum charging termination voltage shall be 4.2v, which cannot be overcharged, otherwise, the battery will be discarded due to too much lithium ions in the positive electrode. Its charge and discharge requirements are high, can use the special constant current, constant voltage charger to charge. Normally, the constant current charge is turned into the constant voltage charge after reaching 4.2v/throttle. When the constant voltage charging current falls below 100mA, the charge shall be stopped
