Product Description: The module adopts CN3768 charge management IC lead-acid batteries must use three-stage charging, the charging process for the automatic charging process, constant current, constant voltage and float charging are three stages of three-stage charging must be. Three-stage lead-acid battery charger charging process is as follows:
1. Constant current charging stage, the charger charging current is kept constant, the charging power increases rapidly and the battery voltage rises;
2. Constant voltage charging stage, the charger charging voltage remains constant, the charging capacity continues to increase, the battery voltage rises slowly, and the charging current decreases;
3. The battery is full, the charging current drops below the float conversion current, the charging voltage of the charger decreases to the float voltage; 4. Float charging stage, the charger charging voltage is maintained at the float voltage.
