Reconditioning The Battery - Black+Decker BC15BD Instruction Manual

TO CHECK THE BATTERY VOLTAGE IN CHARGING MODE:
Press the battery voltage check button and the LCD screen will display the following:
The digital display shows the current voltage of the connected battery for 10 seconds. During this period,
pressing the battery voltage check button again will return the unit to charging mode. Pressing the alternator
check button or the battery recondition button will have no effect. The unit will automatically return to
charging mode after 10 seconds.
When disconnecting charger, disconnect AC cord, remove clamp from vehicle chassis, and then remove clamp
from battery terminal.
Using the Alternator Check Function
Set up the battery charger and connect to the battery following steps 1 through 2 in the "Charging the Battery"
section.
PART 1
No Load (turn OFF all vehicle's accessories): The battery must be fully charged before testing the
alternator. Run the engine long enough to achieve normal idle speed and verify there is a no-load voltage.
1. Press the alternator check button to start the check. The LCD screen will display the following to indicate the
unit is analyzing the alternator:
"Check" will flash, and the alternator icon and the gage without the pointer will light solid.
2. If the unit detects that the alternator is good, the LCD screen will display the following:
"Good", the alternator icon and the gage without the pointer will light solid.
3. If the unit detects that the alternator is out of typical voltage range, the LCD screen will display the following:
The fault icon will flash; and the alternator icon, "ALT" and the gage without the pointer will light solid.
4. Press the alternator check button again to stop the test.
PART 2
Under Load (accessories ON): Next, load the alternator by turning on as many accessories as possible
(except for A/C and Defrost).

1. Press the alternator check button to start the check. The LCD screen will display the following to indicate the

2. If the unit detects that the alternator is good, the LCD screen will display the following:

3. If the unit detects that the alternator is out of typical voltage range, the LCD screen will display the following:
The fault icon will flash; and the alternator icon, "ALT" and the gage without the pointer will light solid.
4. Press the alternator check button again to stop the test.
Notes:
All buttons except the alternator check button are disabled in alternator check mode.
The unit may detect that the alternator is out of typical voltage range because someone has added a number of accessory loads on
the charging system, thereby increasing current demand from the alternator. MAKE SURE THAT THE ALTERNATOR IS RATED TO
SUPPORT THE APPLICATION.
This check may not be accurate for every make, manufacturer and model of vehicle. Check only 12 volt systems.
When disconnecting the charger, disconnect AC cord, remove clamp from vehicle chassis, and then remove
clamp from battery terminal.

Reconditioning the Battery

Periodic reconditioning is recommended to maintain a battery's optimum performance. Battery recondition
sends a series of electrical pulses to break up the crystalline form of lead sulfate and turn these chemicals into
useful battery electrolytes. The process will stop automatically after 24 hours. To stop the process sooner, press
the battery recondition button a second time. More than 24 hours may be needed to restore performance on
some batteries. If so, repeat the process.
1. Set up the battery charger and connect to the battery following steps 1 through 2 in the "Charging the
Battery" section.
2. Press the battery recondition button. The LCD screen will display the following:
The battery recondition indicator, the clamp icons, the battery icon and the gage without the pointer will light
solid, the bars on the battery icon will change from solid to empty (top to bottom) repeatedly and the battery
recondition icons will flash.
3. To stop the reconditioning process, press the battery recondition button again. Pressing any other button
during this process will have no effect.
IMPORTANT: If 5 cycles of reconditioning does not improve battery performance, discontinue and recycle the
battery. The battery charger will go into charging mode after 24 hours automatically.
