In case of an over temp, “OT” will be displayed, and the cycle will pause until the temperature comes down,
then restart. To avoid intermittent starting and stopping, tests should be conducted at temperatures below 95
degrees Fahrenheit.
5.
When complete, minimum voltage, actual voltage, and cycle time can be viewed by using the menu button.
Cycle time refers to the time it took to reach 1.75 volts per cell. To figure capacity, you must know how many
minutes the battery is rated for at the discharge rate selected, you then divide the actual time by the rated time to
find the percent capacity.
Example:
A 12 cell battery set is rated at 107 minutes @ a 75 amp discharge rate. The actual time it took to reach 1.75
volts per cell is 90 minutes therefore capacity is 84%.
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- 400 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 four times, select 25, 56 or 75 amps.
NOTE:
Model BD3648 will only test at
25 and 56 amps at 48 volts. 75 amps is not available.
History:
The discharger holds 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; Therefore, 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.
