Tests below are based on 12V, 60Ah, CCA580A:

1. Battery test

Battery Test results

please continue using the battery.
The battery is in good condition, please charge the battery.| Because the voltage of storage battery is lower than 12.3V, so the performance of storage battery is good, please continue using the storage battery after it is fully charged.

Retest after charging

| Because the battery voltage is lower than 12V, so please retest after it is fully charged. Incorrect reading may occur

if the battery is not fully charged. Please replace the battery if “Retest after charging” displays again after charging.

Replace the battery| Replace the storage battery.
The battery is in bad condition, replace the battery.| ****

Battery inside is damaged, replace the storage battery.

1. Battery capacity (SOC): The percentage of remaining battery capacity,
   • SOC= ×100%. Remaining capacity Actual capacity
2. Battery voltage (VOLTAGE): The voltage value of storage battery (Unit: V).
3. Battery life (SOH): State of health of battery storage,
   • SOH= ×100%. Actual capacity Nominal capacity
4. The measured cold-start current: The measured cold-start current of tester.
5. Nominal cold-start current: Nominal cold-start current of storage battery
6. Internal resistance of battery (R): The measured internal resistance of storage battery.

NOTE: For low-capacity battery (For example, the vehicle is shut down for a long time, the battery is not charged in time, the battery power is significantly lost because the vehicle door is not closed.), the tester may prompt you to “Replace battery” during actual measurement, please consult the storage battery factory and charge the battery according to the designated method, and then retest.

Cranking test

Test results

Charging test

Test results:

engine is 13.5V~14.7V.
Charging voltage is low.| Charging system is under-voltage, the voltage is lower than 13.5V.
Charging voltage is high.| The voltage of charging system is higher than that of vehicle voltage stabilizer.
No voltage output.| Generator voltage output is not detected.

Check if the connector and generator belt is normal.

Diode test.| Test via current waveform, for example, the diode is damaged due to high ripple voltage of diode.
