The signs and symptoms of a dead car battery, how to avoid losing electricity

The battery is a very important and indispensable part of the car. It provides electricity for the start of the car and the electronic equipment in the car. What are the symptoms if the car battery is dead?

Signs and symptoms of dead car battery

1. The car will have symptoms of difficulty in starting, or even failure to start.

2. When the car is idling or decelerating, the brightness of the headlights will dim.

3. The sound of the horn becomes smaller.

4. The battery fault light on the instrument panel lights up.

The car battery also loses about 1% of its electricity every day without any electrical components and no load. This is the self-discharge rate of the car battery. The self-discharge rate is directly related to the quality of the battery. The better the battery, the purer the electrolyte and the lower the self-discharge rate. Therefore, try to avoid using electrical appliances in the car after the car is turned off, because using electrical appliances when the engine is not generating electricity will always consume battery power, and battery loss will affect the car's start-up.

How to avoid power loss

The reason for the lack of electricity in the car battery is usually because the on-board electrical appliances are not turned off after getting off the car, and some are the cause of the generator or battery failure. If the vehicle is parked for a long time, it is recommended to remove the negative electrode of the battery to avoid the battery from running out of power. In addition, when the car is parked for a long time, the car needs to be started regularly. It is best to start the car every other week to let the car run at idle for a period of time, so that the internal generator can charge the battery.
