Smartgen BAC1203聽Battery Charger Description :

Fit with up-to-date power supply device, float charger BAC1203 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.


  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 current protective circuit聽for short-circuit protection聽and reverse connection protection. If failure occurs, power indicator and charging indicator will flash rapidly.
  4. Suitable for 12V storage battery and the rated current is 3A;
  5. LED display: Power indication聽(Green light)聽and charging indication聽(Red light);

Charging is performed according to the battery charging characteristics using two-stage method.聽Charging type is 鈥瀋onstant current type鈥 which means that when the battery terminal voltage falls below聽the pre-set value, charging current will be constant; when the battery terminal voltage exceeds the聽pre-set value, charging current will decrease with the rising of terminal voltage until the pre-set current聽value is reached; then Chargers automatically return to float mode and the charging indicator will聽illuminate. As soon as charging current value falls below 0.3A and the constant voltage value is reached,聽the battery is basically charged (charging indicator will extinguish). After that charging current will only聽neutralize the battery self discharge. Even long-term charging cannot harm the battery, as charger can聽keep the battery fully charged and so guarantee long lifetime of the battery.
