1 OVERVIEW
BAC06 series 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
1) Designed in switching power structure, wide range of AC voltage input, small volume, light weight
and high efficiency;
2) Two-stage charging method (constant current firstly and then constant voltage), fully considering
charging property of the lead-acid battery, can avoid overcharging and extent extend the battery life
to the fullest;
3) With short circuit and reverse connection protection;
4) Charging voltage and current can be adjusted via potentiometer on the spot;
5) LED display: Power indication and charging indication;
6) Horizontal type for installation of BAV06A, easy to install;
7) Vertical type for installation of BAC06V, furthest decreased installation dimension.
3 CHARGING PRINCIPLE
Chart 1. Charge Principle
According to charging property of the lead-acid battery, BAC06V 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.
Thus the charger can maintain a full charged condition and extend 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 battery voltage is under 25.0V (12.5V), adjust the current
potentiometer (AMP) and set proper charge current. Output current can also be estimated according
to the current potentiometer, which is recommended.

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, 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. After correcting the connection and
changing another fuse, it can continue working.
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 gen-set is running, high current will cause voltage drop in charging line, so recommend
separately connecting to battery terminal to avoid disturbance on sampling precision.
6.2 BAC06 SERIES 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 without voltage outputting, and then remove the output fuse tube to visually observe whether
fuse is blown or not, if condition permit, multimeter can be used to measure the fuse status.
a) If output terminal 10A fuse is blown, users only need to change the same capacity fuse.
b) If output fuse isn’t blown or battery without outputting after changing the fuse, battery needs to depot
repair.
c) Fuse burn emergency method: using conductive metal wire short connected burnt fuse, and then
change the fuse later.

6.2.2 PROCEDURES OF CHANGING FUSE
a)Press hard 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.
