Difficult to start the car or it is related to the battery

In the cold winter, the power consumption of car batteries is much greater than in other seasons. Insufficient battery power is one of the main reasons why the car is difficult to start. Because the battery is a frequently used device, there will be loss and discharge intentionally or unintentionally, which will cause the battery to be insufficiently charged. The electric power of the battery is one of the primary powers for starting the car. Once the power is insufficient, the car will definitely not be able to fire normally, and even other electrical equipment will not work properly.　　 To maintain the battery, first of all, for the maintenance-free battery, it is generally necessary to observe whether to replace it through the circular inspection port on the top. Usually it is blue-green when it is normal, and white or yellow when it is abnormal. In addition, the liquid level can be observed through the prompt line of the electrolyte level of the battery case. For batteries that are not maintenance-free, if they are used for a long time, they should be sent to the service station for a thorough charge, and electrolyte should be added to keep the batteries in good working condition.　　The service life of a general battery is two to three years. Vehicle batteries that are close to their service life, especially automatic models, are best replaced in advance to avoid mishaps.　　 In addition, the measures that can be performed for maintenance operations include replenishing the electrolyte of the battery and adjusting the specific gravity of the electrolyte. At the same time, clean the battery terminal and apply special grease to protect it to ensure reliable startup and prolong battery life.　　 If the vehicle is parked in the open air or in a garage for several weeks, the battery should be removed and stored in a warmer room to prevent damage to the battery from freezing.
