How much is the car battery discharge normal, how to discharge the battery

You should know that some electrical appliances in the car are memory functions that need to keep data at all times (such asAudio, Air conditioning, etc.), and the anti-theft sensor also needs long-term power supply to ensure the car’s alarm function. As a result, what we are talking about today is the battery discharge situation. So, how much normal car battery discharge is, and what will happen if it exceeds.

The normal value of automobile discharge is generally around 40mA. Of course, this still depends on the model. It is possible for some high-end cars to reach 80mA. But if the car leakage is 0.09a or more, it must be abnormal. It is likely that there is abnormal leakage in the anti-theft circuit or other circuits. At this time, we need to follow the vine and eliminate them one by one.And the most straightforward way is to remove the correspondingfuseFor example, after the fuse of the anti-theft device is pulled out, if the leakage value returns to the normal range, it means that there is indeed a ground leakage fault in the circuit, and it needs to be dealt with in time.

Of course, the above is only one way to discharge the battery. After the car is used for a period of time, we need to charge and discharge the battery for maintenance.As for how to discharge the battery, the best way is to connect several bulbs in series to the battery. When the bulb is extinguished, it means that it has been discharged.successNS. Secondly, we can also use electric furnace wire to discharge, but this method has certain safety hazards, so it is recommended to use bulb discharge here.
