How long is the life of a car battery?

The life of the battery is also closely related to the climate and the habits of the owner. Under normal circumstances, the service life of the original car battery is more than 3 years.

Valta battery: valta battery in valta is the most famous automobile battery brand in Europe under johnson controls. 1887 was founded in Hagen, Germany, and its AG automotive battery division was acquired by johnson controls in 2002. As a world-renowned supplier of automotive batteries, johnson controls has won many OEM awards. Valta valta has been committed to the research and development of cutting-edge technologies, and has become the first choice of world-famous automobile manufacturers, including close cooperation with first-class automobile manufacturers such as BMW, Ford and Mercedes-Benz. VARTA valta brand lead-acid batteries can be used in conventional cars, start-stop cars, hybrid cars and electric cars. johnson controls Energy Power Business is the first company to provide lithium-ion batteries for mass-produced hybrid car manufacturers. Today, millions of consumers around the world choose to trust VARTA valta's innovative products. In China market, valta provides 100% adaptation for Mercedes-Benz, BMW and Audi.

Function and function of battery: The battery is composed of two different conductors and electrolyte. Through a series of electrochemical reactions, the battery can store and release electric energy. The main function of vehicle battery is to supply power to the engine, ignition system and other electronic equipment when the engine is started. In addition, when the engine is not running or idling, the battery can supply power to the electrical equipment of the whole vehicle for a certain period of time.

What are the factors of battery life?

(1) In addition to the design and manufacturing quality of the battery product itself, the actual service life of the battery is closely related to many factors.

(2) Weather conditions. Compared with areas with lower average temperature, the actual service life of batteries in areas with higher temperature will be shorter.

(3) The number and frequency of electrical appliances in the car. The more appliances in the car, the higher the frequency of use and the shorter the service life of the battery.

(4) Start and stop frequency. Frequent start and stop will shorten the service life of the battery.

(5) Wrong adaptation. Using a battery with a low capacity will shorten its service life.

How to use and maintain the battery correctly in daily use?

(1) Minimize or avoid the use of high-power automotive electrical equipment (air conditioners, stereos, etc.). ) When the engine is off or idling.

(2) Before leaving the vehicle, it must be confirmed that all power supplies have been turned off.

(3) If the vehicle is not used for a long time (for example, more than 2 weeks), it is recommended to temporarily disconnect the negative connection wire of the battery to reduce the energy loss of the battery. Note: Vehicles equipped with on-board computers cannot perform this operation to avoid information loss.

(4) Reduce driving when the temperature is too high.

(4) Go to the 4S shop for battery monitoring regularly.

How to know in advance that the battery needs to be replaced through self-inspection?

(1) The vehicle is more difficult to start than usual, and it needs to be ignited many times, so it feels that the starting power is insufficient.

(2) When idling, the headlights quickly turn from bright to dark, indicating that the battery needs to be replaced.

(3) When the engine starts, it makes an abnormal noise, usually a slight squeak, but it may disappear after two or three seconds or more; As the power is getting lower and lower, the frequency of this noise will gradually increase, indicating that the battery depth is insufficient.

(4) In general, the service life of the battery is 2.5 to 3 years. It is recommended to replace it during this period to ensure driving safety.

Hidden dangers in daily use of batteries;

(1) When the car is started, the engine is not running and the car is running at a low speed, the car battery provides a continuous current for the car and the on-board electrical equipment. After running for a period of time (usually 1-2 years), the performance of automobile battery begins to accelerate and decay until it completely fails. In this "failure period", the battery, as the "fire of life" of the car, is actually in a state of barely meeting the demand of the car, and the specific hazards that may be caused are as follows:

(2) Potential safety hazard: it affects the brightness of headlights and the sound of speakers, which has an impact on safety.

(3) Damage to the automobile power system: Repeated ignition will greatly accelerate the wear and tear of the engine, which may lead to poor engine start, unstable idle speed, poor acceleration and even battery explosion.

(4) Vehicle-mounted electrical appliances are damaged: voltage instability has a great influence on electrical equipment (GPS, stereo, etc.). ), and even lead to equipment damage.

(5) Computer data loss: The complete failure of the battery (power failure) will lead to the loss of data stored in the on-board computer, and it is both costly and time-consuming to unlock it again.

(6) Unable to start, the road broke down: According to statistics, more than 80% of the roads broke down because of batteries, which was time-consuming and laborious, resulting in unnecessary extra expenses.
