How long can car batteries last? How to maintain the battery

After parking, the car’s electric equipment includes headlights, taillights, reading lights, and radios or CDs. The reporter searched the mainstream models currently on the market, and the battery capacity is basically between 35Ah and 45Ah. The power of the headlights is mostly 55 watts per unit, the power of the tail lights is 5 watts per unit, the power of the reading light is 5 watts per unit, and the power of the radio is also 5 watts per unit. The power of the CD player will be higher than that of the radio. The maintenance staff of the 4S shop analyzed that according to relevant experience, when the car battery is good, the working time of the 35Ah battery is about 3 hours, and the working time of the 45Ah battery can be slightly longer when the headlights, reading lights, and radio are turned on. One point, between 3 to 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 time to continue power supply. 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. To charge the battery often, how to judge that it is time to charge the battery so as not to let the battery be in a state of depletion. The maintenance staff said 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. If the brightness of the car lights is dimmed, the battery will be in a state of power loss by that time, and the car must be paralyzed and unable to start. In order to ensure the normal operation of the battery and prevent the car from being paralyzed, it is best for the car owner to start the engine to charge the battery once every half an hour when the battery is in use. When the battery runs out, what method should be used to start the car? The maintenance personnel recommended three methods: cart start, tow 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 often because it will damage the engine and clutch to a certain extent. The method and principle of traction start are similar to that of cart start. The lap start is to start the vehicle by lapping with another battery. Maintenance of the battery must be done well. 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. General storage batteries can be used for 2 to 3 years. But if the usage is unreasonable, 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 of the battery, which will easily affect the battery. Cause damage. The car lights are the same. 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 you start 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 be wary of battery power loss, because if you lose power, it is easy to cause damage to the battery. At present, there is a technology that can repair damaged batteries, using pulse charging technology to activate the battery electrolyte, and it can be used continuously. But if the power loss is serious, the battery will be scrapped in advance. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
