Description

| Interpretation
---|---

The battery is in good condition.

| The performance of storage battery is good, 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=  Remaining capacity/Actual capacity×100%.

2. Battery voltage (VOLTAGE): The voltage value of storage battery (Unit: V).

3. Battery life (SOH): State of health of battery storage,
   SOH=Actual capacity/Nominal capacity ×100%.

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.
