With the development of the automotive industry, cars have gradually replaced people's traffic, then the car is composed of many components. As the owner, we have more than just driving, but also need to understand the use of each component and the service life. Car batteries are one of them. Many riders don't know the relevant knowledge of car batteries. Here are some related knowledge about car batteries that the car owners have compiled. How long can the car battery be used? How to replace it? .
Many car owners have the habit of parking and listening to music. When they are ready to start the car, they can't start it. The power consumption can't be activated. If the car owner doesn't pay attention to this situation, the battery will be scrapped soon. Recently, due to the hot weather, it is not uncommon to stop there to listen to music, etc., which causes the car battery to run out of power and the car can't start.
How long can the car battery last?
After parking, the car's power equipment has headlights, taillights, reading lights, and a radio or CD. At present, the mainstream models on the market, the capacity of the battery is basically between 35Ah and 45Ah. The headlamp power is mostly 55 watts/piece, the taillight power is 5 watts/piece, the reading lamp power is 5 watts/piece, and the radio power is also 5 watts/piece. The power of the CD player will be higher than that of the radio.
The maintenance staff of the 4S shop said that according to experience, when the car battery is good, the headlights, reading lights and radios are turned on. The working time of the capacity 35Ah battery is about 3 hours, and the working time of the capacity 45Ah battery can be slightly longer. , between 3 and 4 hours. The higher the volume of the radio or CD, the greater the power, so the battery's power usage time, but also consider this issue. In addition, the life of the battery is generally 2 to 3 years, so the new and old batteries also affect the length of the continuous power supply. If the user installs some appliances that are not originally installed, such as a subwoofer, it will cause excessive use of the battery. If the battery is old, do not work for more than 2 hours.
Always charge the battery
How to determine if the battery needs to be charged? The 4S shop staff told Xiaobian that it is really difficult to judge. It is impossible to judge the working state of the battery by the brightness of the headlights or the strength of the sound. If the brightness of the lights is dark, the battery will enter the loss at that time. The state of electricity, the car must be "瘫痪", can not be launched. In order to ensure the normal operation of the battery, do not let the car "squat", the owner will start the engine to charge the battery once every half hour when the battery is in use.
When the battery is running out of power, what method should I use to start the car? Maintenance personnel recommended three methods: cart start, traction start and lap start. The first two methods are suitable for manual transmission models. He said that the start of the cart is the most familiar and most effective emergency start method, but it is a last resort and cannot be used frequently because it has certain damage to the engine and the clutch. The method and principle of traction start is similar to the start of the cart. The lap start is to start the vehicle by lapping with another battery.
Maintenance of the battery to get the law
Maintenance personnel said that in the maintenance of the car, the maintenance of the battery is also very important. If you develop bad habits, it will shorten the service life of the battery or cause damage. A typical battery can be used for 2 to 3 years. However, if the use is unreasonable, it may take 3 to 4 months to replace it.
Nowadays, there are more and more electric devices on the car. Therefore, when using these electric devices, the owner should try not to overload the battery. Taking electric windows and skylights as an example, the owner should complete its lifting and closing before the engine is turned off, because if the engine is turned off, it will stop generating electricity. At this time, lifting the window will increase the load of the battery, which will easily cause the battery. damage. The same is true for the lights. If there is no special need to turn off the fire, the headlights should be turned off first, then the fire should be turned off. When starting the car at night, the headlights should be turned on and then turned on to minimize damage to the battery.
If the battery is operated while the engine is stopped, be sure to prevent the battery from losing power, because if the power is lost, it is easy to cause damage to the battery. There is now a technology for repairing damaged batteries, using pulse charging technology to activate the battery electrolyte and continue to use it. However, if the power loss is serious, the battery will be scrapped in advance.
The above is some of the use of car batteries by the small series to the owners, I hope that the owners can learn more about this issue to ensure their safety.
