![]() ![]() This counteracts the battery’s self-discharging or any loads applied to the battery. It will then maintain this voltage in order to keep the battery topped up. The BCDC will reduce current to the battery to allow the voltage to fall to its Float voltage of 13.3V. Note: the charger’s output current will change in line with any loads applied to the battery to prevent the need for the BCDC to skip or revert stages. A shorter duty-cycle (shorter illumination time of the LED) indicates less current into the battery. As the charging current decreases the LED will flash to reflect this. The LED will indicate Absorption when the full charge voltage is being applied. When the current falls below 4A for 30 seconds the charger will enter Float stage. 14.5V for profile A selection).Ĭurrent: Will be gradually falling. Voltage: Will be stable at the Absorption voltage (e.g. What you would expect to see on a multi-meter in ABSORPTION stage: The battery is fully charged at this time. 14.5V for profile A selection), the charger will hold the absorption voltage for a predetermined period of time or until the current being drawn by the output battery drops to less than 4A for 30 seconds after which the charger will enter Float stage. Once the battery reaches 100mV less than the Maximum Charge Voltage (e.g. As the battery voltage reaches the maximum charge voltage the LED will flash to indicate the current into the battery is falling. The LED will indicate Boost when the full charge current is being applied. Voltage: Between the battery resting voltage and absorption voltage, will increase gradually as battery charges.Ĭurrent: Full charger capability, will stay constant until the voltage rises to the maximum charge voltage. What you would expect to see on a multi-meter in BOOST stage: The current in boost stage may vary during operation to maintain safe operating temperature, or to limit the difference between input and output voltages. ![]() Generally, Boost stage will deliver the first 70- 80% state of charge, depending on the battery type. The voltage will gradually rise in the battery as its state of charge increases. It maintains a constant current until the battery voltage reaches its maximum voltage. In this stage the LED is on solid and the BCDC is applying maximum current to the battery. ![]()
