We all know that the life of car batteries is not long, only 2-3 years. Many friends will damage the battery because of improper use and discharge quickly. What actions will damage the battery? Nowadays, cars are not so much machines as household appliances with a large number of electronic components.
The biggest fear of electronic equipment is that it will not be used for a long time, just like there will be problems if the mobile phone is not used for a month or two. Just like a car, driving less is the biggest damage to the battery, because the battery will continue to consume energy to maintain basic functions such as unlocking and vehicle memory if it is not charged for a long time, so it is easy to be damaged due to power failure.
Therefore, it is recommended that car owners, if they can foresee that the vehicle will be parked for more than two weeks, don't forget to open the hood of the engine compartment and remove the negative electrode of the battery, so as to prevent the battery from being damaged. To a large extent, even if the negative electrode is removed, it is recommended to reinstall the pilot head every month and start the vehicle for 30 minutes to fully charge the battery.
Driving on the road at night, it is easy to find that some cars don't turn off the lights and the owners are not in the car. The headlights can only be turned on for one night, and as a result, 80% people can't even start the car the next day. Some car owners often make such a hasty mistake, forgetting to turn off the headlights after turning off the lights, or turning off the headlights automatically before turning off the lights at night and turning them on automatically the next day.
However, the owner forgot to turn them off again. If this happens for a long time, it will cause some damage to the battery. It is suggested that car owners pay more attention to it and get into the habit of turning off the air conditioner first, then the headlights and then the engine. In order to avoid being scratched when parking, many car owners choose a driving recorder with 24-hour parking monitoring function.
Because the monitoring recorder uses constant power after the engine is turned off, it has been consuming battery power. Generally speaking, the driving recorder consumes 12AH of energy in 24 hours, which is about 1/4 of the energy of the car battery, so the new car battery can support the recorder for 3~4 days in an ideal situation, but when the car battery is less than half.
When the voltage is lower than 134V, it will be difficult to start. Therefore, if you don't use the car every day, it is recommended to turn off the 24-hour parking monitoring and don't start it often. Some people even start after three to five seconds. A bigger impact will shorten the battery life.
When the vehicle is not started, turning off the stereo and listening to high-power sound will bring great pressure to the battery and cause serious damage to the battery. At this time, the generator of the vehicle does not work, and the battery is in an "idling" state and is not charged. Reducing its capacity will cause the vehicle to fail to start, and excessive discharge will cause great damage to the battery itself.
Headlights are not turned on by switches. Headlights have independent power supply and switch. If the switch is not turned on, the headlights will still be on, especially the headlights consume a lot of electricity. If the headlights are turned on for a long time and the engine is not started, the battery will not be dead. However, if the battery is low, the vehicle may not start.
If it is an automatic headlight, and some have home mode, you can choose how many seconds the headlights will light up after locking the car. In fact, this function is of little use, almost 15, 20 seconds, or it can be used if the setting is unclear, otherwise it will damage the battery more or less. A car is a means of transportation. As long as you take good care of it, the battery will not be damaged so easily.
