How to Test CCA and CA for Car Battery

Testing Cold Cranking Amps (CCA) and Cranking Amps (CA) is essential for determining the health and performance of your car battery. CCA measures the battery’s ability to start an engine in cold temperatures, while CA indicates its performance at warmer temperatures. To test these values, you can use a multimeter or a specialized battery tester that provides accurate readings.

Understanding CCA and CA

Both CCA and CA are critical metrics for evaluating a car battery’s performance, especially in varying temperature conditions.

• Cold Cranking Amps (CCA): This rating indicates how much current a battery can deliver at 0°F (-18°C) for 30 seconds while maintaining a minimum voltage of 7.2 volts. It is crucial for starting engines in cold weather.
• Cranking Amps (CA): This measures the amount of current a battery can provide at 32°F (0°C) for the same duration. CA ratings are generally higher than CCA ratings, reflecting better performance in warmer conditions.

How to Test CCA and CA

Testing your car battery’s CCA and CA can be done using the following methods:

1. Using a Multimeter

A multimeter can help you measure the voltage of your battery, but it does not directly measure CCA or CA. However, you can check if the battery voltage is within acceptable limits before performing further tests.

• Steps:
  • Turn off your vehicle.
  • Set the multimeter to DC voltage.
  • Connect the red probe to the positive terminal and the black probe to the negative terminal.
  • A healthy battery should read around 12.6 volts or higher.

2. Using a Battery Load Tester

A battery load tester is designed specifically to measure CCA and CA ratings.

• Steps:
  • Ensure the battery is fully charged.
  • Connect the load tester according to the manufacturer’s instructions.
  • Apply a load equal to half of the CCA rating for 15 seconds.
  • Observe the voltage drop; it should not fall below 9.6 volts during the test.

3. Using a Specialized Battery Tester

A specialized battery tester can provide precise readings of both CCA and CA without needing to apply a load.

• Steps:
  • Connect the tester’s clamps to the respective battery terminals.
  • Follow on-screen instructions to initiate testing.
  • Read the displayed values for both CCA and CA.
