B. Battery Type Selection
GEL
: Sealed type (VRLA) , GEL , Maintenance Free , Automotive or Deep Cycle lead acid batteries
WET
: Flooded Type lead acid batteries (to which water can be added) Automotive or Deep Cycle
Calcium-Calcium : Calcium-Calcium type batteries are to be charged in this mode only when boost is required (15.5V). No load
is to be connected to the battery during this charge mode. Charge through one cycle only then set back to
WET charge setting.
B1. FLOAT VOLTAGE SELECTION
These fine tuned selections of float voltages enable the best voltage level for maximum battery life. Choose 13.8V when in doubt
or in Power Supply Mode.
Follow the markings on Deep Cycle batteries of the Standby float voltage.
B2. Recommended Battery Capacity
The following minimum AH capacities are a generalized suggestion, some batteries can take higher charge current, check with
battery manufacturers for charging batteries with smaller capacity.
Charger Model
BC-1210 ,10A
BC-1215 ,15A
BC-1220 ,20A
Battery Capacity
40 AH - 100 AH
60 AH - 150 AH
80 AH - 200 AH
C. Battery Charger Installation and Connection
Observe the warnings & safety precautions before connecting the charger.
Check battery condition, fill up cells for wet battery, clean battery posts.
Secure the battery charger in a well ventilated place, make sure the mounting surface is flat. The air intake is at the bottom and air
outlet at the back. Make sure both intake and outlet are not blocked. Never place charger on top of battery.
Plug in the AC mains and turn on Power Switch , the Charger On LED and the Float LED should be on green indicating Charger is
in good order for charging.
Before connecting or disconnecting the charging cable, turn off the Power Switch and unplug AC cord from the mains.
First connect the Red cable to Po terminal of charger and the battery Po Post. Then connect the Black cable to the
Negative – terminal and the Negative – Post of the battery.
Make sure all the connections are tight and secure.
Double check again for correct selection of Slide Switch 1 at Charger Mode, Switch 2 for Battery type and Switch 3 for Float
Voltage setting value.
D. Normal 3 Stage (IUoU) Charging Operation
The 3 stage IU0U charge algorithm ensures fast , complete and at the same time gentle charging of the lead acid battery.
