Approximate Charging Times - Black & Decker BDSBC20A Mode D'emploi

ENGLISH

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:
20Ah 60Ah 180Ah 360Ah 450Ah
30A 0.18 hr 1.00 hr 3.00 hr
*** *** ***
25A 0.20 hr 1.35 hr 3.5 hr
*** *** ***
20A 0.33 hr 2.10 hr 5.00 hr
*** *** **
Note: This table is for indication only. Please note that these
times may vary depending on the condition of the battery
and the environmental condition in which the battery is being
charged.
The times shown in the table above are approximate and are
based on a 50% discharged battery. The battery charging
times will vary depending on the size, age and condition of
the battery.
Alternator check (fig. B)
A faulty alternator can be the hidden cause of a discharged
battery.
Warning! Check only 12 Vdc systems.
Part 1 (no load)
Make sure that there is no load on the alternator by
turning off all the vehicles accessories.
The battery must be fully charged before testing the
alternator.
Run the engine for 3 minutes to achieve normal idle
speed and verify that there is a no-load voltage.
Using the function control knob (3), select alternator
check (fig. C) before connecting the clamps to the
battery, ANALYSING ALTERNATOR will be displayed
after the clamps are connected.
When the unit has completed checking, ALTERNATOR
GOOD will be displayed and the green LED will light to
indicate that the alternator is good or ALTERNATOR
BAD or ENGINE NOT RUNNING and the red LED will
light to indicate that the alternator is out of typical
voltage range.
Part 2 (under load)
Load the alternator by turning on as many accessories
as possible except for air-conditioning and defrost.

Once the unit has completed checking, ALTERNATOR
GOOD will be displayed and the green LED will light to
indicate that the alternator is good or ALTERNATOR
BAD or ENGINE NOT RUNNING and the red LED will
light to indicate that the alternator is out of typical
voltage range.
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:
Loose fan belts.
An intermittent diode failure.
Bad connections between the battery and alternator
and/or ground.
Note: ALTERNATOR BAD or ENGINE NOT RUNNING may
be displayed if 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.
Engine start (fig. C)
Using the function control knob (3) select engine start before
connecting the clamps to the battery.
The LCD will show a 90-second count down, then
READY TO JUMP START ENGINE will display.
Crank the engine using the manufacturers guidelines,
typically in 3 to 5 second bursts. The LCD displays
STARTING.
Disconnect the mains cord and clamps observing the
"Safety instructions" at the front of this manual.
Warning! When a second attempt at starting an engine is
required, a five minute cooling down period is necessary
before attempting to re-start the engine.
The high current engine start function requires a resting/
cooling period between tries. The charger will not allow
operation in the engine start mode for 5 minutes. The LCD
will display COOLING DOWN, WAIT 5 MINUTES during this
time. After 5 minutes, repeat the above procedure.
Troubleshooting
Display indications, common problems and possible
solutions:
No Functions
Make sure that the battery charger is plugged into a live
230 Vac outlet.
Follow the steps outlined in the "Connecting the battery
charger" at the front of this manual.
The unit will turn on automatically after being properly
connected to the battery. If it does not come on, either it
is not connected properly to the terminals or the voltage
of the battery to be serviced is too low (below 0.5 Volts).
