It is said that in winter, car batteries are prone to performance degradation due to low temperatures, thus greatly shortening the battery life. But now in the hot summer, car battery replacement has gradually entered the "peak period". Why is this? Maybe many riders can't figure it out for a while. Isn’t it said that the performance of the battery will increase when the temperature is high?
That’s right! Maybe you still remember a rough experience that Dahuyou told you before: the capacity and performance of ordinary batteries are experimental data produced by the manufacturer in a laboratory with a constant temperature of 25 degrees. The temperature is lower than 25 degrees. When the temperature decreases by 1 degree, the battery capacity also decreases by about 1% (not precise, but roughly so, easy to remember). Therefore, the lower the temperature, the worse the battery performance. This is common sense.
So when the temperature is high, will the battery "live more comfortably"? Here we need to bring you new knowledge: In fact, when the temperature of the battery is higher than 25 degrees, the performance will indeed improve! Surprised? ——When the temperature is above 25 degrees, the battery capacity will increase by approximately 1% for every 1 degree increase in temperature. Of course, the battery performance will no longer increase when it reaches 40 degrees, so the temperature increase is indeed beneficial to the battery.
About the misunderstandings between batteries and air conditioners
Since this is the case, shouldn’t batteries have “frequent problems” in summer? Don't worry! Dahu Yu continued! In fact, the frequent replacement of batteries in summer is really related to the temperature! The theme song of summer is the word "hot", so driving with air conditioning in summer has become something you can't refuse. There is indeed an inevitable connection between turning on the air conditioner and the battery.
Some car friends may ask, is the car air conditioner powered by electricity? ——Dahu You saw that many riders interpreted it this way. So here Dahuyou would like to briefly introduce the relevant knowledge: the compressor of the car air conditioner is directly driven by the engine and does not consume electricity. Therefore, when the engine is turned off, the air conditioning compressor will stop.
Perhaps at this point, car enthusiasts will ask again: In this case, why is the use of air conditioners in summer related to battery life? In fact, the reason is very simple: although our engine stalled and the air-conditioning compressor automatically stopped, the air-conditioning blower did not stop! That is to say, the blower is still running continuously, which is also a power-consuming thing!
Incorrect use,
is the main culprit that causes battery damage
In summer, many car owners temporarily park to wait for others (or those who "do not go upstairs after arriving home and need to A man who "calm down in the car for a few minutes"), because he is afraid of the heat, keeps the air conditioner blowing. At the same time, he feels that it is quite boring to be alone in the car with nothing to do, so he turns on the car stereo and listens to music. If it is at night , even the car lights were turned on... Of course, I was afraid of wasting gasoline when I parked for a long time, so I turned off the car...
You said that the engine was not working at this time, so the generator was also in hibernation. In this state, the entire car's power consumption is provided by the battery, and the burden on the battery can be imagined (not all cars have the function of automatically protecting the lights after turning off the engine)! If you play like this frequently, it will easily damage the battery in the long run. After all, the battery is very afraid of being short of power for a long time.
Of course, if the battery is damaged and the vehicle cannot be started, there are now dedicated road power rescue services, and they are free. For example, the services provided by the insurance company, such as Tu Rover's roadside assistance service, etc., we can make full use of at critical moments. However, whether road rescue can save the vehicle depends on whether the battery has been completely damaged, and the success rate of rescue cannot be guaranteed to be 100%.
It’s not easy to make money, but you should take good care of your car
Therefore, as car owners, we try to develop good habits of using cars rationally. After the engine is turned off, we try to turn off unnecessary electrical appliances. equipment. But if the battery is really completely damaged, the only way left is to replace the battery. Of course, there are also many services that deliver batteries to your doorstep, such as Tuhu.
Tuhu's battery can be delivered to the location agreed by the car owner, and then the "continuous power replacement" operation can be performed on-site in front of the car owner. At present, many excellent mainstream battery products are also available in Tuhu, such as the Varta that we are very familiar with. The brand's patented "Power Grid" technology is famous for its strong starting current, high number of starts, stable starting current, and ultra-low temperature start. , so Valta’s voice is very high among the car enthusiasts.
Although most of the service industries today can provide very user-friendly and convenient services, as a car owner, I think you still need to protect your car well and ensure that there are as few or even no failures as possible. It includes the knowledge of protecting your car battery. Always keep one principle in mind: Turn off all unnecessary electrical equipment as much as possible after the engine is turned off. This is the best way to extend the life of your car's battery!
