The three-stage lead-acid battery charger operates as follows:\u003c\/p\u003e\u003cp\u003e1. Constant Current Stage: Charger maintains a steady current, rapidly increasing charge input while battery voltage rises.\u003c\/p\u003e\u003cp\u003e2. Constant Voltage Stage: The charger maintains a constant charging voltage. The charge continues to increase, the battery voltage rises slowly, and the charging current decreases.\u003c\/p\u003e\u003cp\u003e3. When the battery is fully charged, the charging current drops below the float conversion current, and the charger's charging voltage decreases to the float voltage.\u003c\/p\u003e\u003cp\u003e4. Float Charging Stage: The charger maintains the charging voltage at the float voltage.\u003c\/p\u003e\u003cp\u003eProduct Parameters:\u003c\/p\u003e\u003cp\u003eAC Input Interface: Low-voltage AC input, AC 12-20V\u003c\/p\u003e\u003cp\u003eDC Input Interface: DC input, DC 15-30V\u003c\/p\u003e\u003cp\u003eBattery Interface: Connects to 12V lead-acid battery; B+ for positive terminal, B- for negative terminal\u003c\/p\u003e\u003cp\u003eIndicator Lights:\u003c\/p\u003e\u003cp\u003eLED1: Charging status indicator, illuminates during charging\u003c\/p\u003e\u003cp\u003eLED2: Battery connection indicator, illuminates when battery is connected\u003c\/p\u003e\u003cp\u003ePackage Contents:\u003c\/p\u003e\u003cp\u003eCharging Module*1\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003ch4\u003eQ: What is the 12V Battery Charging Module CN3768 Three-stage Constant?\u003c\/h4\u003e\u003cp\u003eA: The 12V Battery Charging Module CN3768 Three-stage Constant is a quality decor pick.
