1 OVERVIEW
Fit with up-to-date power supply device, float charger BAC2410 is specially designed for meet the
charging characteristics of the lead-acid engine starter batteries and can be used for long-term float
charging of 12V lead-acid batteries.
2 PERFORMANCE AND CHARACTERISTICS
1) Switch power supply structure, wide input alternating voltage range, small size, light weight, high
efficiency rate;
2) Automatic two-stage charging process (first constant current, then constant voltage) carried out
according to storage battery charging characteristics to prevent overcharging and significantly
prolong battery lifetime;
3) Built-in PFC circuit can calibrate the power factor above 0.99;
4) Built-in current protective circuit, which can give effective protection when output over current,
short-circuit or reverse connection occurs. Regard power lamp or charge lamp fast blinking as alarm;
5) Suitable for 24V storage battery and the rated current is 10A;
6) LED display: Power indication (Green light) and charging indication (Red light).
3 CHARGING PRINCIPLE
Three-stage Method
Charging is performed according to the battery charging characteristics using three-stage method.
1) The first stage is named as ‘constant current’: when the battery terminal voltage falls below the
pre-set value;
2) The second stage is named as ‘constant voltage’: when the battery terminal voltage exceeds the
pre-set value, charging current will decrease with the rising of terminal voltage until the pre-set
current value is reached; then Chargers automatically return to float mode. As soon as charging
current value falls below 0.5A and the constant voltage value is reached, the battery is basically
charged (charging indicator will extinguish). After that charging current will only neutralize the
battery self discharge. Even long-term charging cannot harm the battery, as charger can keep the
battery fully charged and so guarantee long lifetime of the battery.

NOTE:
1) Because there is diode and current-limiting circuit inner the charger, it can be used together with charging generator,
and there is no need to disconnect the charger when cranking;
2) During genset is running, high current will cause voltage drop in charging line, so recommend separately connecting to
battery terminal to avoid disturbance on sampling precision.
