    What prompts will the car battery tester have when charging?
    If my battery is in good condition but only needs to be charged, what will the car battery tester battery tell me?
    A manager responded to this review
    Yes, it will tell you if the battery only needs to be charged or if it needs to be replaced. The unit operation is very simple. It can also test the car's charging system.
