10. Let up on accelerator pedal and record the lowest reading observed on voltmeter (the min/max feature
works well for obtaining the lowest reading on the battery during testing).
11. Repeat steps 5 - 10 on each battery individually.
NOTE: If tested after a full charge, the individual battery voltages should not drop below 11.5 volts for a
12 volt battery, and 7.5 volts for an 8 volt battery. Also, there should not be a difference of more than
0.5 volts between the highest battery reading, and any other battery reading.
This test can also be done at any time the battery charge is within the operating range. Sometimes the
problem might have to be duplicated before executing this procedure, for the results to show the weak battery,
or batteries. When testing at this point, especially watch for a difference of more than 0.5 volts between the
highest battery reading, and any other battery reading.
In cases where vehicles are programmed with a stall-out, do not hold the pedal to the floor longer than one cut
off by the controller, per battery, or allow 30 seconds of cooling time for the motor and controller following stall-
out.
H: Carbon Pile Load Test Procedure
Batteries should be fully charged before testing.
1. Take a voltage reading of each battery, record these readings.
2. Disconnect the battery cables from the battery that is being tested.
3. Observe the correct polarity and make sure the test leads are making good contact with the battery
posts.
4. Turn the load control knob (if the tester is so equipped) to draw current at the rate of three times the
battery's ampere-hour (AH) rating or ½ of its CCA rating.
5. Maintain the load for 10-15 seconds.
6. Observe the tester's voltmeter to read the lowest voltage for each battery, and record the readings.
7. For ambient temperatures at or above 70°F, or for testers that are temperature compensated, battery
voltage at the end of 10-15 seconds should not fall below 10.5 volts for a 12 volt battery, or 6.5 volts for
an 8 volt battery.
NOTE: It is important to observe ambient temperature as this will greatly affect test results.
