This situation may be that the battery is dead, or the whole vehicle is poorly charged, and the rectifier is not charged, not necessarily that the battery is broken. First, charge the battery with a charger, and charge it with a small current (current 1 A or less) for 10 hour before loading the test, or leave it for 2-3 days after charging, and then load the test. At this time, if the battery can hit the car, it means that the battery is normal, and it is necessary to check whether the vehicle is insufficiently charged and whether the vehicle circuit has self-discharge.
