Some careless car owners often forget to turn off the lights when parking. When I went to drive the car the next day, the battery of the car was dead and the car was normal. Parking is a big problem for novice drivers with no driving experience. So what if the car battery is dead? Today, Bian Xiao will teach you several first aid methods.
Use emergency power supply
When the car battery is dead, we can use the emergency power supply in the car to charge the car. Its function is similar to that of mobile phone charging treasure, which can be said to be the savior of automobile battery. If there is no emergency power supply in the car, but there is a "rescue car" with electricity and an "emergency" power cord, we can take electricity to charge the car battery. Generally, after a rescue vehicle drives for half an hour, it can basically ensure that the battery has enough power for the second start. If there is neither an emergency power supply nor a rescue vehicle that can get electricity, then when the car battery is dead, you can only call the rescue phone for support.
Generally speaking, the service life of automobile batteries is 2-3 years, and it can be extended to 3-5 years if it is well maintained. So how do we usually maintain the battery? First of all, we should try our best to avoid over-discharge of the battery, especially after we park the car, we must check whether the car headlights and the ceiling light in the car have been turned off. If you forget to turn off the headlights after parking, the computer of the vehicle does not have the function of automatically turning off the lights, and the probability of not touching the car the next morning can reach 99%, and the damage of excessive discharge to the battery is also very great.
In addition, if you don't drive for a long time, you must unplug the negative electrode of the battery. Although the car is parked there, there is a weak current consumption in the vehicle circuit system, and the battery will be exhausted in the long run. Therefore, if the car does not run for a long time, we should unplug the negative electrode of its battery to avoid the loss of the battery.
When we maintain the car battery, we should not only avoid excessive discharge of the battery, but also get rid of these bad habits of damaging the battery. First of all, the first bad habit is frequent starting, especially in the northern winter when the temperature is relatively low, and the battery activity itself is not very good. If frequent continuous starting has a great influence on the discharge of the battery, it will affect the service life of the battery.
Did not turn off the air conditioner in time.
The second bad habit is not to turn off the air conditioner before turning off the engine, which will cause the air conditioning system to start automatically when we start the car next time, and the instantaneous power load of the car will become very high, which will damage the battery in the long run.
Long-term short-distance driving
The third bad habit is driving short distances for a long time. If we only drive two or three kilometers a day, it is impossible to fully charge the battery. If the automobile battery is insufficiently charged for a long time, its service life will be greatly affected.
In addition, when we maintain the car battery, we should also pay attention to cleaning the car battery regularly and checking the usage of the car battery regularly.
If you want to make the car battery more durable, you must pay attention to the above points.
