The battery should be maintained in this way in winter

As a very important part in the car, the main function of the battery is to start the engine and act as a power supply station for the electronic equipment of the whole car at low engine speed. So as long as the battery cannot supply power normally, there will be problems with the engine or the electronic system on the car. In winter, because the temperature of the operating environment is generally low, and the power consumption of the car is more than other seasons, so in order to avoid various failures, it is very necessary to maintain the battery in winter.

Routine inspection of batteries in winter

The inspection of the battery is actually relatively simple. First of all, it is necessary to ensure that the battery is firmly fixed in the cabin to prevent the battery case from breaking due to vibration. For voltage detection, in fact, as long as a baby energy meter is used, the health status of the battery can be judged. Connect the positive and negative poles of the multimeter to the positive and negative poles of the battery. If the measured voltage value is greater than 12V, it means that the battery is normal. If it is lower than 10.5V, it is not far from being scrapped, and it is best to replace it in time.Also read:

The optimal temperature for battery use is 25 degrees. If the temperature drops by one degree, the relative capacity will drop by about 0.8%, the viscosity of the engine oil will increase greatly, and the resistance will also increase greatly during operation, so the car will start quickly. It's difficult.

Battery maintenance in winter

The temperature in winter is low, and the starting time should not be too long. This is to prevent the battery from being seriously lost due to long-term high-current discharge. As for the starting time of the car, it should be controlled at about 3 to 5 seconds, and the stop should be kept at 20 to 30 seconds between two starts. Today's batteries are maintenance-free, do not need to add distilled water for normal use, the terminals will not corrode, have less self-discharge, and have a long life. There are also some vehicles that use dry-charged batteries, no matter which one is prone to insufficient power and low voltage at low temperature, so you must pay attention when using them.

In winter, if the vehicle is placed in the garage or not used for a long time in the open air, then the battery must be removed and placed in a warm room to prevent damage from freezing inside the battery. Because the battery is in an environment below minus 10 degrees, the battery will freeze after being discharged, and the frozen battery needs to be thawed before charging. If it is not thawed and charged directly, it may cause an explosion. It is best to use a small battery The current charges slowly.

In addition, in winter, people often use functions such as seat heating, steering wheel heating, rearview mirror heating, and defogging. These functions will increase power consumption, thereby increasing the pressure on the battery. Pay more attention to checking the battery to prevent power loss.Also read:

Precautions for battery use in winter

When parking and turning off the engine, don't forget to turn off the lights in the car. After the battery is consumed overnight, it is likely to lose power and cause the car to fail to start. Some people are not used to turning off the air conditioner before the vehicle is turned off, and the next time the air conditioner is turned on, it will start at the same time, which will cause the vehicle's instantaneous power to be too high and the battery load to be too large, which will be a loss to the battery over time.

In winter, the vehicle sometimes fails to start. At this time, people will start the vehicle frequently, but be careful not to rush to start repeatedly after each failure. Each start should not exceed 3 seconds, and the interval between restarts after start failure should exceed 5 seconds.
