BATTERY CAPACITY TEST
1. Set the BC-8000 on a stable surface. Connect the AC power cord (4161-10) to the power source. Connect the DC
cord (4161-50) to the battery. Set the AC power switch to the ON position.
2. Check the battery manufacturer’s component maintenance manual (CMM) for the minimum percent capacity
setting. The minimum percent battery capacity test settings are 80%,85%, and 100% in the BC-8000. The setting
can be changed in the CONFIGURE menu. A capacity test that falls below the minimum percent selected will be
identified as a failed capacity test.
3. With MODE? Displayed on the BC-8000 display, select CAPACITY ? by pressing the UP or DOWN button. Press
the NEXT button to advance the display menu.
4. Now select the battery voltage 12 or 24 volts by pressing the UP or DOWN button. Press the NEXT button to
advance the display menu.
5. Push the NEXT button. Select the End Point Voltage (EPV) cutoff. The default EPV is 20 volts for 24V battery and
10 volts for a 12V battery. The BC-8000 allows for EPV adjustment from the default values. For a 24V battery the
EPV can be lowered to 18 volts. For 12 volt batteries the EPV can be lowered to 9 volts. Check with your battery
manufacturer for specified EPV points. Press the NEXT button to advance the display menu.
6. With CAPACITY C1 AMPS? Displayed, select the battery manufacturer’s C1 (one hour) battery discharge
amperage rate by pressing the UP or DOWN buttons. Press the NEXT button to advance the display menu.
7. The BC-8000 will display CAPACITY START TEST? To start the test, press the NEXT button again. If you wish to
stop the test before the End Point Voltage (EPV) is reached, press the NEXT button and the BC-8000 will stop
testing. If testing is stopped before EPV is reached the battery must be recharged following the battery
manufacturer’s recharge procedures before retesting.
8. After pressing the NEXT button to start the test, the BC-8000 cooling fan motor will start and the LCD display
will show the C1% reading, battery voltage, flash Testing / EPV voltage setting, and test amperage. Note: While
the BC-8000 is testing or at the conclusion of the test, pressing the UP button will display the test run time in
minutes. The LCD will display TM: 60.2’ (The symbol ‘ indicates minutes)
9. Upon reaching the EPV the BC-8000 capacity test will stop. The cooling fan motor will stop and the audio beeper
will beep if enabled. The display will show the C1 battery capacity percentage. Test amperage and Pass or Failed
is displayed.
If the BC-8000 COOLING FAN MOTOR FAILS TO START press the NEXT button stopping the test. Place the
OFF/ON switch to the OFF position and return the BC-8000 for service.
“Passing” is the battery manufacturer’s minimum percentage of the batteries one-hour capacity rating.
“Failing” is a battery that falls below the manufacturer’s minimum percentage of the one-hour capacity rating.
Before returning the battery to service follow the battery manufacturer’s recharging procedure.
