How long can the car battery last? After parking, the car's power equipment has headlights, taillights, reading lights, and a radio or CD. The author searched for the mainstream models on the market, and the capacity of the batteries 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. 4S shop maintenance staff introduced, according to experience, in the case of good car battery, turn on the headlights, reading lights, radio, the working time of the capacity of 35Ah battery is about 3 hours, and the working time of the capacity of 45Ah battery can be a little longer, Between 3 hours and 4 hours. The higher the volume of the radio or CD, the greater the power, so the battery's power usage time should 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. He warned the owner that if the battery is old, it is best not to work for more than 2 hours. Always charge the battery Then, how to judge when the battery should be charged, so that the battery is not in a deficient state? The maintenance personnel said that it is really impossible to judge. Can not rely on the brightness of the headlights or the strength of the sound to determine the working state of the battery, if the brightness of the lights is dark, at that time the battery has already entered a state of loss, 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 "squeaky", the owner should preferably start the engine to charge the battery once every half hour while the battery is in use. When the battery is running out of power, what method should I use to start the car? The 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 be replaced after 3 months to 4 months. 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.
