Step-by-Step Guide: How to Use the BT-3006FT Battery Load Tester

Before testing, always review the official operating manual provided by the manufacturer.

Step 1. Identify the Battery’s Rated Capacity

Locate the Cold Cranking Amps (CCA) rating printed on the battery. For example, a battery may be labeled as “720 CCA.”

Step 2. Connect the Tester

Attach the positive (red) lead to the battery’s positive terminal, and the negative (black) lead to the negative terminal. Ensure solid connections, as high current will be applied during testing.

Step 3. Adjust the Load

Turn the carbon pile rheostat to increase the load until the ammeter needle matches the battery’s CCA rating on the tester’s scale.

Example: If the battery is rated at 720 CCA, rotate the load knob until the ammeter reads 720 on the appropriate scale.

Step 4. Observe the Voltage Drop

Monitor the voltmeter as the load is applied. A 12V battery in good condition should not drop below 9.6 volts under full rated load.

Step 5. Time the Test

Maintain the load for no more than 10 seconds. Prolonged testing can damage the battery or skew results.

Step 6. Interpret the Results

• If voltage stays above 9.6V: The battery is in good condition.

• If voltage drops below 9.6V: The battery may be failing or unable to deliver its rated performance.

Step 7. Disconnect Safely

Once testing is complete, reduce the load to zero, then disconnect the leads.
