1. Battery Health Test is mainly to analyze, calculate the health status of the battery and judge the aging degree of the battery ( Displays 5 test results, and tells you whether you should replace or charge the battery)
2. Start System Test is mainly to detect and analyze the starting motor, detect the actual starting
current and starting voltage required by the starting motor
3. Charging Health Test is to check and analyze the charging system, including generators, rectifiers, rectifier diodes, etc.

5 Battery Test Results(Battery Health Test):
1. Good battery - Indicates that the battery is normal.
2. Replace battery - Indicates that the battery is aged or becomes rejected, or the battery life cycle is nearly exhausted. In this case, battery voltage appears to be normal, but the battery itself is not well, i.e. battery polarity board has been completely vulcanized or aged. Please replace the battery immediately.
3. Good-recharge - Stands for low battery. The battery is good itself.
4. Charge-retest - It is better for a few batteries to be fully charged before testing in order to avoid judging in error under special conditions.
5. Bad cell - Indicates one of the battery cells is bad and cannot work
normally, but for which one is bad, it can’t be verified. In this case, battery voltage is generally lower than 11V, mainly resulting from internal circuitry damage, such as short circuits, open circuits, dummy welds, etc. LAUNCH CRB3001 OBD2 Scanner and Battery Tester Specification:
