1 OVERVIEW
Fit with up-to-date power supply device, charger BAC1203VE 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 with the maximum output current 3A.
2 PERFORMANCE AND CHARACTERISTICS
─Switch power supply structure, wide input voltage range, small size, light weight, and high
efficiency rate;
─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;
─Built-in current protective circuit for short-circuit protection;
─Suitable for 12V storage battery with the maximum charging current 3A;
─LED display: Power indication and charging indication.
3 CHARGING PRINCIPLE
Fig.1- Charging Principle
Charging is performed according to the battery charging characteristics using two-stage method.
Charging type is ‘constant current type’ which means that when the battery terminal voltage falls below
the pre-set value, charging current will be constant; 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 voltage value
exceeds 13.5V, the battery is basically fully charged. 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.
