DISCHARGING LEAD-ACID (Pb) BATTERIES
1. To discharge lead-acid batteries, ensure the correct battery memory or parameters have been
in the charger.
2. Connect the battery to the charger.
3. Use the jog dial to locate the DISCHARGE icon and press to begin discharge.
4. When the battery has fi nished discharging, the screen will show “Completed” and tones will sound.
NOTES ABOUT DISCHARGING Pb BATTERIES:
• For more accurate discharge readings, it’s better to use a current which can discharge the
battery in 2 or 4 hours.
• The maximum discharge current is 3 amps. The actual amount of current drained from the
battery might be limited for higher voltage Pb batteries due to the chargers max. power rating.
This is normal.
• The proper discharge cutoff voltage for batteries with a nominal rated voltage of 6V is 5.4V, and
24V batteries should be discharged to 21.6V.
Channel 2
Channel 2 is a charge ONLY output and may be used independently or while Channel 1 is being
used. This allows two packs, of different chemistries, to be charged at the same time. Channel
2 is completely separate from the Main Menu associated with Channel 1. There is no model
memory selection. Therefore, prior to charging a battery, the parameters must be changed to
match the battery.
1. To access Channel 2, press the “CH” button located on the
front panel.
2. Use the jog dial to change the settings to match that of your
battery specifi cations. Press the dial and rotate to change to
the desired setting. Press to confi rm.
3. After battery connections have been made and programming
is completed, press the dial to begin the charge process. A
confi rmation screen will appear as it does for Channel 1. Press
the dial to confi rm the correct number of cells is connected to
the charger.
4. During the charge process or after the charge has fi nished, various information can be accessed
by pressing the < or > keys. This is the same information that is displayed on channel 1.
5. When charging has fi nished, press the ESC button to exit or simply unplug the battery.
Cooling Fans
This charger has three built-in cooling fans (as shown on page 5) that aid in keeping the charger
cool during operation. This will help extend the service life of the charger and allow it to function
more accurately and effi ciently. CAUTION: Do not block any of the fans or vent holes for the cooling
fans on the charger. Failure to do so could cause the charger to overheat and possibly cause
permanent damage.
