The importance of car batteries

When the car battery is good, turn on the headlights, reading lights, and the radio. The working time of the 35Ah battery is about 3 hours, while the working time of the 45Ah battery can be slightly longer, between 3 and 4 hours. The higher the volume of the radio or CD, the greater the power. Therefore, the battery life should also be considered. In addition, the battery life is generally 2 to 3 years, so the new and old batteries also affect the length of the continuous power supply time. If the user privately installs some electrical appliances that did not exist before, such as a subwoofer, it will cause excessive use of the battery. He warned car owners that if the battery is old, it is best not to work more than 2 hours.　　How to maintain battery 　　The maintenance personnel said that in car maintenance, 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. General storage batteries can be used for 2 to 3 years. However, if it is used unreasonably, it may be replaced in 3 to 4 months.　　 Nowadays, there are more and more electric devices in cars, so when car owners use these electric devices, try not to overload the battery. Taking power windows and sunroofs as examples, car owners should complete their lifting and closing before the engine is turned off, because if the engine is turned off, power generation will be stopped. At this time, raising and lowering the windows will increase the load on the battery, which is likely to cause damage to the battery. damage. The same is true for car lights. If you want to turn off the fire, there is no special need. You should turn off the headlights first, and then turn off the fire. When starting the car at night, you should also turn on the headlights first and then turn on the headlights to minimize damage to the battery.　　 If you let the battery work when the engine is stopped, you must prevent the battery from losing power, because it is easy to damage the battery if it loses power. Now there is a technology that can repair damaged batteries, using pulse charging technology to activate the battery electrolyte, and it can continue to be used. However, if the power loss is severe, the battery will be scrapped in advance.　　It is necessary to charge the battery often　　So, how to judge that the battery should be charged so as not to let the battery be in a state of depletion. The maintenance staff said that they really couldn't judge. The working status of the battery cannot be judged by the brightness of the headlights or the strength of the sound of the sound. If the brightness of the lights is dimmed, the battery will be in a state of power loss by that time, and the car must be 'paralyzed' and cannot be started. . In order to ensure the normal operation of the battery and prevent the car from being 'paralyzed　　When the battery runs out, what method should be used to start the car? The maintenance personnel recommend three methods: cart start, traction start and overlap start. The first two methods are suitable for manual transmission models. He said that the cart start is the most familiar and effective emergency start method, but it is a last resort and cannot be used frequently because it will damage the engine and clutch to a certain extent. The method and principle of traction start are similar to those of cart start. The lap start is to start the vehicle by lapping with another battery.
