Proper Care and Use of Batteries:
CAUTION:
Always wear protective eye shields and clothing
when working with batteries. Batteries contain acids which can
cause bodily harm. Do not put wrenches or other metal objects
across the battery terminal or battery top. Arcing or explosion of
the battery can result. Do not wear jewelry when working around
batteries. Arcing can cause severe burns.
New batteries will not deliver their full performance until after
several cycles.
The tops of the batteries and battery hold downs must be kept
clean and dry at all times to prevent excessive self discharge and
flow of current between the battery post and frame.
Maintain the proper electrolyte level by adding water when
necessary. Never allow the electrolyte level to fall below the top
of the battery plates. Electrolyte levels fall during discharge and
rise during charging. Therefore, to prevent the overflow of
electrolyte when charging, add water ONLY AFTER the batteries
have been fully charged. DO NOT OVERFILL. Old batteries require
more frequent additions of water than new batteries.
Do not over discharge the batteries. Excessive discharge can cause
polarity reversal of individual cells, resulting in complete
battery failure.
Identifying Defective Cells/Batteries:
During the discharge cycle, batteries should be monitored by
voltage individually, and should stay fairly even. Batteries that
drop faster than the others are probably defective. Batteries that
fall much below 1.75 volts per cell should be replaced. Bad
batteries are obviously related to lower capacity ratings. Some
experience is required to judge if the pack capacity is sufficient for
the actual use it will be subjected to.
Reprogramming the Discharger:
The time adjustment is from 5-245 minutes. To change, press and
hold the MENU button until the time is displayed. Press the
START/STOP/PAUSE button to initiate change, then press either
button to increase or decrease time. Stop pressing, and time will
be held in memory.
To change shut off voltage -
Press the button a second time after
MAX TIME is displayed. Raise or lower shut off voltage in the same
fashion.
To change the discharge rate -
Press the button 4 times, select 25,
56 or, 75 amps on 36 volt pack – 25, or 56 amps on a
48 volt pack.
History:
The discharger holds 14 previous tests in the history menu. To
access, press the MENU button 5 times. The display will show run
time, start voltage, and shut off voltage. The first record is the last
cycle run.
Attention:
The cable length and size is critical to volt meter accuracy - do not
change. Clamp tightness is also critical. If the clamps become hot
during discharging have them replaced.
WARNING:
Failure to disconnect clamps from battery pack
before moving or driving equipment will result in damage to
cords, clamps, and equipment.
