Black & Decker BDV1085 Instruction Manual page 7

Pressing the 2/10/30A pushbutton (15) again advances the
charging rate to 10 A, and pressing the pushbutton once
more advances the charging rate to 30 A. (Pressing the
pushbutton again will turn OFF the battery charger output
and the digital display (1) will show 000).
Note: This selection and the actual battery charge rate are
monitored by the microprocessor, and the appliance will stop
charging if the selected rate is too fast or too slow for battery
size or condition.
As the battery nears full charge capacity, the appliance's
output will automatically drop to a lower charge rate.
Pressing the 2/10/30A (15) button repeatedly advances to
stand-by mode; the appliance sounds a beep, displays 000
and stops charging.
The battery charger displays the charge current.
To view the battery voltage, press the battery voltage
pushbutton (14). The charger will sound a beep and display
the battery voltage. Press the battery voltage pushbutton
(14) again to return to displaying the charge current.
The digital display (1) shows FUL when the battery is fully
charged.
Disconnect the ac power cord first, then the negative
clamp, and finally the positive clamp.
Automatic float charging (fig. A)
The automatic float charge feature is ideal for maintaining a
battery. It automatically tops off the battery as required to
keep the battery fully charged all the time.
Keep the ac power and battery connected when the battery
has been fully charged.
The charger monitors the battery and tops it off as needed.
The float charge LED (6) lights and the digital display (1)
shows the charge current when topping off the battery and
returns to FUL when completed.
To view the battery voltage, press the battery voltage
pushbutton (14).
Warning! If the battery size is not known, charge at the 2 A
rate. DO NOT overcharge batteries.
Equalizing (fig. A)
Equalizing is the process by which the fluid in each of a
battery's cells is equalized.
This process occurs after charging is complete.
Warning! Never try to equalize a maintenance free type
battery. The resulting explosion could cause property damage,
serious injury and/or death.
Remove or disconnect the vehicle's battery when
equalizing.
The frequency which the equalization process needs to be
run depends on the use of the battery. The more the battery
is used, the more undercharged it becomes; thus the more
frequently the battery should be equalized.
Do not use this mode on sealed or valve regulated batteries.
This mode is only meant for wet (unsealed/vented) batteries.
Make sure that there are no flammable sources near the
recharging site.
Wear safety glasses, gloves and protective clothing.
Remove the battery from the vehicle. Make sure that the
battery has good ventilation. The process causes the
release of hydrogen and oxygen. An accumulation of these
gases presents a real danger of explosion.
Open the battery cap, if removable.
Fill the battery with distilled water according to the
manufacturer's instructions. Since batteries may rapidly
bubble while being charged, remember to refill (only with
distilled water) after the equalization process is complete
and the voltage is back to normal.
Follow the steps in the "Charging the battery" section.
Push the battery type pushbutton (16) until WET is
displayed (this mode will only work if a WET battery is
selected).
Choose the correct charge rate and start charging. You can
check the battery voltage by pushing the battery voltage
pushbutton (14). This will trigger the battery voltage
LED (7).
Push the equalize pushbutton (9) at any time and the
battery will automatically begin to equalize in 4 A limited
current.
Note: To push the recessed pushbutton you will need a
small pin or a ballpoint pen.
Check the temperature every hour by touching the battery.
If the battery is hot to the touch, stop the charging and
allow the battery to cool.
The voltage rises to between 15.3 V to 16.2 V (2.55 to 2.7 V
per cell) depending on the ambient temperature, it will
automatically adjust.
The WET LED (10) flashes while the battery charger is in
equalize mode.
The digital display(1) will show FUL when the equalization
process is complete.
Engine start (fig. A)
The engine start function can supply 80 A for engine starting.
Set the 2/10/30A pushbutton (15) to the 30 A mode and
immediately press the 80A pushbutton (12) to activate the
engine start mode.
The digital display (1) will countdown from 999 to 000.
When a count of 000 is reached and the digital display (1)
begins to flash, the vehicle is ready to start.
