Overview of the battery charger (fig. B)

The Black & Decker battery charger has a fast-charge rate
of up to 10 A, and a slow rate of 2 A. It is designed for
charging 12 V 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.

The battery charger features 3-stage high-efficiency
charging technology using built-in microprocessor control
which ensures fast, safe and complete charging of
serviceable batteries.

Stage 1 - rapid start charge

Stage 1 is a rapid start charge at 10 A to deliver maximum
charging amperage to "wake up" any serviceable 12 V
battery and allows for quick engine starting. When the
battery reaches a maximum safe predetermined voltage, the
battery charger will beep and begin stage 2 of the charging
process.

Stage 2 - absorption charge

Stage 2 is an absorption charge which maintains the
maximum possible charge at a constant, safe,
predetermined voltage. During this phase, the charging
voltage remains constant, while the charging current is
reduced to allow for the maximum proper internal chemical
energy transfer.

At the end of stage 2, the battery charger will automatically
begin stage 3 of the charging process.

5

Stage 3 - top-off charge

Stage 3 is a top-off charge. The voltage is automatically
regulated and is reduced to a predetermined level while the
current is adjusted for a safe, effective battery charge. At the
conclusion of stage 3, the appliance will beep, signalling the
completion of the charging cycle.

Function pushbuttons (fig. A)

The function pushbuttons on the control panel (3), from left
to right, are:

SLOW/FAST pushbutton (11) (charge rate
selector step 2). This pushbutton allows the user
to select the charge rate based on the battery
size. This selection and the actual battery charge
rate are monitored by the microprocessor. The
battery charger will stop charging if the rate is too
fast or too slow for the battery size or condition.

Battery voltage pushbutton (10). This pushbutton
enables a check to measure the battery voltage.

Alternator check pushbutton (9). This pushbutton
enables a five-second check that measures the
battery voltage. This check is repeated at various
electrical load levels and the tests allow the user
to determine if the alternator can keep up with
the loads. It can indicate whether an alternator
service may be required.

Control panel LEDs (fig. A)

The following icons are shown on your battery charger:

Fault LED (5). Lights when any of several faults
are detected, see F01 through F05 Codes as

changes.

X Pressing the SLOW/FAST pushbutton (11) again will

advance the charge rate to fast rate and displays FAS.
Pressing the pushbutton (11) again will turn OFF the
battery charger output and the digital display (2) will show

000.

Note: This selection and the actual battery charge rate are

monitored by the microprocessor and the unit will stop
charging if the selected rate is too fast or too slow for battery
size or condition.

X As the battery nears full charge capacity, the unit's output

will automatically drop to a lower charge rate.

X The digital display (2) shows the charge current. To view

the battery voltage, press the battery voltage pushbutton
(10). The battery charger will sound a beep and display the
battery voltage.

Part 1 (no load)

X Make sure that there is no load on the alternator by turning

off all the vehicle's accessories.

X The battery must be fully charged before testing the

alternator.

X Run the engine long enough to achieve normal idle speed

and verify that there is a no-load voltage.

X Press the alternator check pushbutton (9) to start the

check.

X The alternator good LED (8) will light to indicate that the

alternator is good, or the fault LED (5) will display to indicate
that the alternator is out of typical voltage range.

X Press the alternator check pushbutton (9) again to stop the

test.

Part 2 (under load)

X Load the alternator by turning on as many accessories as

possible, except for air-conditioning and defrost.

X Press the alternator check pushbutton (9) to start the test.
X The alternator good LED (8) will light to indicate that the

alternator is good, or the fault LED (5) will light to indicate
that the alternator is out of typical voltage range.

X Press the alternator check pushbutton (9) again to stop the

test.

If the first alternator check indicates a good alternator and
the second indicates the alternator is not good, the problem
could be caused by any of the following:

X Loose fan belts.
X An intermittent diode failure.
X Bad connections between the battery and alternator and/or

ground.
Note: The battery voltage pushbutton (10) is disabled in the
alternator check mode.
Note: The fault LED (5) may display because a number of
extra accessory loads have been added to the charging
system, thereby increasing current demand from the
alternator. Make sure that the alternator is rated to support
the application.
Note: This check may not be accurate for every make,
manufacturer and model of vehicle.

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.

For estimates of the time it takes to charge a battery, refer to
the following table:

% of charge in the battery

Rate 75% 50% 25% 0%

2A 7 hrs 14 hrs NR* NR*
6A 2.5 hrs 4.7 hrs 7 hrs 9.2 hrs
10A 1.4 hrs 2.8 hrs 4.2 hrs 5.5 hrs

*NR = Not recommended at 2 A - use a higher charge rate.

The times shown in the table above are approximate and
refer to a 50 Ah automotive battery.

Example

A 50 Ah, 12 Vdc battery is discharged (50%). To determine
the time it takes to charge at the 10 A rate, see the chart
above under "50%" and "at 10 A rate".

The battery charging times will vary depending on the size,
age and condition of the battery. Smaller batteries should be
charged at a slower rate (SLO) and an extra hour added to
the charge time.
