Performance Features
BAC series switch - type battery chargers adopt the latest switching power supply technology. Designed based on the charging characteristics of lead - acid batteries for starting generators, BAC chargers are suitable for long - term supplementary charging (floating charging) of lead - acid batteries. The maximum charging current is 6 amperes for 12 volts and 10 amperes for 24 volts. |
Automatic charge using the 2-stage charging method(i.e., constant current first and then constant voltage). The process is in full accordance with the battery charging characteristics, and can prevent overcharging of lead-acid battery and maximize battery life. |
Have protection functions for short-circuit and reverse connection. |
Have protection functions for short-circuit and reverse connection. |
LED display: Power indication and charging indication. |
Horizontal installation. Easy to install. |
Charging Principle
BAC chargers employ a two-stage intelligent charging protocol that aligns with battery charging characteristics:
1. Constant Current (CC) Phase: Delivers a fixed current when battery voltage is below the threshold.
2. Constant Voltage (CV) Phase: Once voltage reaches the threshold, current gradually decreases until it drops to the cutoff value (0.3A, or 0.5A for 24V 5A models), triggering a transition to float charging. Voltage slowly stabilizes at the set value, and the LED indicator turns off, signaling near-full charge.
3. Float Maintenance: A minimal trickle current compensates for self-discharge without overcharging, preserving battery capacity and lifespan

Configuration
- Voltage regulation |
- Current regulation |
Connect the output to the battery. Measure the charging current when the charging voltage is not higher than 25.0V (12.5V). Regulate the current potentiometer (AMP) to set the appropriate charging current. The output current can also be estimated according to the current potentiometer scale. |
Operation Instruction
1. Connect AC 220V to terminals L and N. BVR multiwire copper wires are recommended. Wires for 3A/5A/6A
chargers should be no thinner than 1mm2 ; wires for 10A chargers should be no thinner than 1.5mm2 .
2. Connect terminal B+ to “+”of battery; connect terminal B- to“-”of battery. BVR multiwire copper wires are recommended.Wires for 3A/5A/6A chargers should be no thinner than 1.5mm²; wires for 10A chargers should be no thinner than 2.5mm² .
3. POWER：green indicator of power status. On when charger works normally.
4. CHARGING ：red indicator of charge status. On when the charge current is larger than 0.3A(0.5A).
5. VOLT：regulator potentiometer of charging voltage.
6. AMP： regulator potentiometer of charging current.
7. The output FUSE is 10A. The fuse will burn out if the output is wired reversely. At this time, there is no output voltage.After correcting the output wiring and replacing the fuse, the charger can work normally.
8. Steps of fuse replacement:
8.1. Use a screwdriver to press in slightly and screw counterclockwise a little. Then pull the fuse out.(unsuitable operation or excessive force may damage the fuse holder)
8.2. Insert the new fuse into the fuse holder. Use a screwdriver to press in slightly and screw clockwise a little.
** Note ** :
1.The internal output of the charger is connected to diode and current limiting circuit. The charger can be used in parallel with the charging generator on the engine.
It is not necessary to disconnect the charger when starting.
2.When used on generator sets, it is recommended to connect the charging cable to the battery terminal separately, because a voltage drop will be generated on the charging cable due to the high charging current, which can affect the sensor sampling accuracy.

FAQ
1. What are the main features of the BAC06A series battery charger?
It has a switch - power structure with a wide input voltage range, small volume, light weight, and high efficiency. It uses a two - stage charging method, has short - circuit and reverse - connection protection, adjustable charging voltage and current, LED status display, and is easy to install horizontally.
2. How does the charging process of the BAC06A series battery charger work?
It first charges in constant - current mode when the battery voltage is below a threshold. When the battery voltage exceeds the threshold, the charging current decreases as the voltage rises until it reaches the set voltage, and then it switches to floating - charge mode. When the charging current is lower than 0.3A (0.5A for 24V 5A), the battery is basically fully charged.
3. What are the wire - gauge requirements for connecting the BAC06A series battery charger? Wires for 3A/5A/6A chargers should be no thinner than 1.5mm2, and wires for 10A chargers should be no thinner than 2.5mm2.
