OPEN CIRCUIT VOLTAGE TEST
NOTE: BOTH JAWS OF EACH CLAMP MUST FIRMLY ENGAGE BATTERY TERMINAL OR IT WILL NOT FUNCTION
PROPERLY.
1. Make sure load knob is in the OFF position.
2. Connect tester positive (+, Red) lead to battery (+) terminal.
3. Connect tester negative (–, Black) lead to battery (–) terminal.
4. If voltmeter reading is less than 12.4 Volts, battery must be charged and retested before continuing. (If battery voltage
is less than 12.4 Volts after charging, replace battery.)
REMOVING THE SURFACE CHARGE
If your open circuit voltage reading is above 12.8 Volts, remove the surface charge before load testing. Failure to do so
will result in inaccurate test readings.
Three possible ways to remove a surface charge:
1. Turn headlights (high beam) on for 3 to 5 seconds.
2. Disable ignition: crank starter over for 10 to 15 seconds.
3. Using a variable carbon pile load tester, load battery for 10 to 15 seconds at 150 amp load.
Make sure load knob is in the OFF position before connection is made or removed.
After removing surface charge, let battery stand for 10 minutes to stabilize.
CALCULATE THE LOAD
WARNING: VARIABLE LOAD CARBON PILE TESTERS PRODUCE HEAT WHEN IN USE. CARE MUST BE TAKEN TO
ALLOW SUFFICIENT TIME TO COOL DOWN BETWEEN TESTS TO AVOID INJURY DUE TO HEAT BUILD UP.
1. Look for either the "Cold Cranking Amps (CCA)" rating or the "Amp Hour (AHr)" rating on the battery decal.
2. If the CCA rating is provided, the load placed on the battery should be on half (1/2) of the Cold Cranking Amps rating.
Example: 600CCA battery – load to 300A.
3. If the Amp Hour rating is provided, the load placed on the battery should be 3 times the Amp Hour rating. Example: 70
AHr battery – load to 210A.
4. If neither the CCA rating nor the Amp Hour rating are not available, refer to battery catalog for nominal CCA rating.
5. Sometimes the rating cannot be located. In that case, the engine size may be used as a guide to determine the battery's
ampere rating. However, it is recommended to use the manufacturer's recommendations whenever they can be located.
