What is the normal discharge current for a car?
1 Answers
The normal range for car leakage current is below 40mA for ordinary cars and below 80mA for high-end cars. Here are the methods for car discharge maintenance: 1. First, use a battery tester to check if the battery is aged. If the test is normal and the battery discharge is caused by human factors, simply charging the battery will suffice. 2. If the vehicle operates normally but the battery is depleted after a few days of inactivity, first check if there is any direct short circuit between the battery terminals caused by accidental connections, then check if all electrical appliances that bypass the ignition switch are functioning properly. 3. Connect a fault diagnostic tool, turn on the ignition switch, and read the fault codes. If there are fault codes, inspect according to the prompts. 4. If there are no fault codes, turn off all electrical appliances and lock the car for a period of time, then use a current clamp or connect a multimeter in series with the negative terminal circuit of the battery to measure the dormant current.
