Black & Decker BDSBC20A Original Instructions Manual page 7

Plug the unit into an ac source and during the
initialisation sequence, press the language button (2)
once; pressing the language button repeatedly allows
you to choose your language.
Once a language has been selected, the smart charger
will display all messages and information in this
language.
The language button does not need to be pressed each time
the unit is switched on; the smart charger remembers the
previous selection and defaults to this language.
General use instructions
Set up the unit as described in the "Connecting the
battery charger" section.
Turn the function control knob (3) to the desired function
position.
Plug the charger into a 230 Vac outlet.
Connect the charger clamps to the battery.
The digital display (1) will show ANALYSING
BATTERY, indicating that the unit is set up correctly and
ready to use.
CHECK BATTERY CONNECTIONS will be displayed
when the unit is plugged in and there is no battery
connected to the charger or the clamps are not
connected properly.
When the unit has completed analysing the battery, it
will begin the recharging process if the function control
knob (3) has been set to smart charge. The battery
voltage will then be displayed (for example;
CHARGING/12.5 VOLTS). As the battery charges, the
arrow on the charging gauge (6) will move indicating the
current percent of charge in the battery, from the red
zone (0 to 25% charged) toward the green zone (75-
100% charged).
When the unit is fully charged, BATTERY IS FULLY
CHARGED will be displayed and the green status LED
light (5) will light.
To turn the battery charger off, first disconnect the
mains cord, then disconnect the clamps (4). Observe
the "Safety Instructions" at the front of this manual when
disconnecting.
Use
The Black & Decker battery charger has a fast charge rate of
20A, 25A or 30A (depending on the model). It is designed for
charging 12V lead-acid batteries only, i.e. conventional
automotive, maintenance-free, marine, deep cycle and gel
batteries as used in cars, trucks, farm equipment, boats,
lawn mowers, garden tractors, motorcycles and various
other applications.
Autoselect technology
Select the application and the charger will do the rest.
4-Stage charging technology (fig. D)
The battery charger features 4-stage high-efficiency
charging technology using built-in microprocessor control
which ensures fast, safe and complete charging of
serviceable batteries.
Stage 1 - battery status
To make sure the battery can accept a charge, a connection
check prevents damage caused by reversed polarity.
Stage 2 - bulk charge
Charges fast by delivering pure DC current up to 80% of the
battery capacity.
Stage 3 - absorption
Avoids overcharging by slowly charging up to 100% of the
battery capacity.
Stage 4 - float mode
Maintains the battery fully charged indefinitely so it is always
ready for use.
Control panel
The following symbols are shown on the control panel:
Smart charge (fig. A)
Automatically analyses the battery and selects the best
charging rate for the battery type, size and discharge level.
Approximate charging times
The battery charger will automatically adjust the charge rate
as the battery becomes charged and stop charging when the
battery is fully charged. Deep cycle batteries may require
longer charging times.
Alternator check (fig. B)
A faulty alternator can be the hidden cause of a discharged
battery.
Warning! Check only 12 Vdc systems.
