1 OVERVIEW
BAC06A switching battery charger adopts the latest switch power components, which is designed for
charging lead-acid starting battery according to its property. The charger is suitable for lead-acid battery
float charge. The maximum charge current for 12V charger is 6A; the maximum charge current for 24V
charger is 3A.
2 PERFORMANCE AND CHARACTERISTICS
Characteristics are as below:
—Designed in switching power structure, wide range of AC voltage input, small volume, light weight and
high efficiency;
—Two-stage charging method (constant current firstly and then constant voltage), fully considering
charging property of the lead-acid battery, can avoid overcharging and extend the battery life to the
fullest;
—With short circuit and reverse connection protection;
—Charging voltage and current can be adjusted via potentiometer on site;
—LED display: Power indication and charging indication;
—Horizontal type for installation of BAV06A, easy to install;
3 CHARGING PRINCIPLE
Chart 1. Charge Principle
According to charging property of the lead-acid battery, battery charger uses 2-stage charging
method and charge mode is “constant-current”. When battery voltage is under the threshold, it is
charging in constant-current mode; when the battery voltage is higher than the threshold，the charging
current is decreasing as the battery voltage is rising until it reaches the set voltage, and then charge
mode is turned into “floating charge”. Charge current is gradually reducing and battery voltage is rising
up to the set value. When charging current is lower than 0.3A, the battery is basically fully charged
(charging indicator eliminates). Afterwards, charging current will offset self-discharge of the battery and
long time charging does no harm to the battery. Thus the charger can not only maintain a full charged
condition and but also ensure the battery life.

5 SETTING
5.1 VOLTAGE ADJUSTMENT
When adjusting the voltage on the spot, disconnect the battery from the charger, and then measure
the output voltage of the charger while adjusting voltage potentiometer (VOLT) to a proper value.
5.2 CURRENT ADJUSTMENT
Connect battery output firstly. When charging voltage is not higher than 25.0V (12.5V) measure
charging current; adjust the current potentiometer (AMP) and set proper charge current. Output
current can also be estimated according to the current potentiometer scales.

6 OPERATION
6.1 PANEL DRAWING DESCRIPTION
Chart 2. BAC06A
—Terminals L and N connect AC 220V, using multi-strand BVR 1mm2copper wires.
—Terminals B+ and B- connect battery positive and negative, using multi-strand
BVR1.5mm2copper wires.
—POWER: Power indicator. When charger works normally, it will illuminate.
—CHARGING: Battery charging indicator. When charging current is over 0.3A, it will
illuminate.
—VOLT: Voltage adjustment potentiometer.
—AMP: Current adjustment potentiometer.
—Output 10A fuse. Reverse connection will cause fuse blown. At this time no output voltage; After
correcting the connection and changing another fuse, it can continue working.
NOTES:
1) Because there is diode and current-limiting circuit inside charger outputs, it can be used together with charging
generator in parallel, and there is no need to disconnect the charger at cranking.
2) For application on genset, high current will cause voltage drop in charging line, so recommend separately connecting to
battery terminal to avoid disturbance on sampling precision.
6.2 TROUBLESHOOTING
6.2.1 FAULT DIAGNOSIS
Output terminal of battery charger short circuit or battery reverse connection may blow the charger
output fuse. In that case, after connecting AC power supply, charger green LED lights up but output
terminal is without voltage outputting, and then remove the output fuse tube to visually observe whether
fuse is blown or not, if condition is permitted, multimeter can be used to measure the fuse status.
a) If output terminal 10Afuse is blown, users only need to change the same capacity fuse.
b) If output fuse isn’t blown or battery is still without outputting after changing the fuse, battery needs to
repair in factory.
c) Fuse burn emergency method: using conductive metal wire, short connected burnt fuse, and then
change a proper fuse later.
6.2.2 PROCEDURES OF CHANGING FUSE
a)Press hard in on the slotted screwdriver, screw counter-clockwise and then take out the fuse.
b)Put a new fuse into the block, press the slotted screwdriver and screw clockwise.
NOTE: improper operation or over tightening may damage the block.
