• CA: 0 ℃ effective starting current rating.
• MCA: Marine battery standard, the effective starting current rating at 0℃.
• JIS: Japanese Industrial Standard, displayed as a combination of numbers and letters on the battery (e.g., 55D23, 80D26).
• DIN: Standard of the German Automotive Industry Council.
• IEC: International Electrotechnical Commission standard.
• EN: European Automobile Industry Association Standard.
• SAE: American Society of Engineers standard.
• GB: China National Standard.

4. Setup

To begin using your V311B Car Battery Tester, follow these steps:

1. Ensure the vehicle's ignition is off and all accessories are turned off.
2. Locate the vehicle's 12V battery.
3. Connect the red alligator clip to the positive (+) terminal of the battery.
4. Connect the black alligator clip to the negative (-) terminal of the battery.
5. The tester will power on automatically once connected correctly.

5.2. Battery Test Modes

The V311B offers several testing modes to assess battery performance:

• Quick Test: Provides a rapid assessment of the battery's health.
• Standard Test: Conducts a more thorough analysis, requiring input of battery specifications.
• Starting Test: Measures the battery's cranking performance during engine start-up.
• Charging Test: Evaluates the vehicle's charging system performance.
• Waveform Analysis: Displays real-time voltage waveforms for detailed diagnostics.

5.3. Interpreting Test Results

After a test is completed, the V311B will display the results on its screen. Key parameters include:

• Volt: Current battery voltage.
• Rated: The rated Cold Cranking Amps (CCA) or other standard value of the battery.
• Measured: The actual measured CCA or equivalent value.
• Resistance: Internal resistance of the battery. Lower values indicate better health.
• Life (SOH): State of Health, indicating the battery's overall condition as a percentage.
• State of Charge: The current charge level of the battery as a percentage.
