In the hot summer days, when I want to use the car air conditioner to cool down, I find that the air conditioner can't start; or I can't "ignite" when I start it. These conditions are caused by the lack of electricity in the car battery . In fact, there is a sign that the battery is dead. Pay attention to the normal use, it can guarantee the normal use time of the battery.
Dongfeng Nissan experts said that when you start the car, the startup time should not exceed 3 to 5 seconds, and the restart interval should be no less than 10 seconds. Also, before leaving the car, check to make sure that all lights and other appliances (such as radio, CD) are turned off, otherwise your battery will be drained.
In addition to the above suggestions, Dongfeng Nissan experts also introduced that the usual short-distance driving starts and stops, which will cause the battery to be undercharged for a long time and shorten the service life. Driving on the highway at a steady speed for 20-30 minutes, you can charge the battery for a sufficient time. Good driving habits are the most important part of ensuring the normal use of the battery.
Before the battery is dead, a small alarm will be issued. For example, the starter does not turn or the rotation is weak, so that the starter cannot be started; the headlights are darker than usual; the speaker volume is small or not, etc., and the signs are before the battery is dead. And some car owners often mistake it for a car's glitch.
If you encounter a battery that is out of power, don't panic. The most familiar method is to start the car to help the car ignite, but this has certain damage to the engine and the clutch. It is recommended as a contingency plan. Do not use it frequently.
Second, it is the use of fire (Jump-Starting, also known as the line). In the process of borrowing fire, you should also pay attention to the connection sequence of the jumper cable when connecting the jumper cables: first connect the positive terminal of the dead battery to the positive terminal of the rescue car battery, and then Connect the negative terminal of the rescue vehicle battery to the metal part of the engine compartment of the non-electric vehicle (grounding wire).
After the jumper cable is connected, the engine of the rescue vehicle can be started, and the engine speed can be slightly increased. After about 5 minutes, the battery can be charged urgently. After charging is complete, the jumper cable should be removed in the reverse order of connecting the jumper cables.
Dongfeng Nissan experts remind the owner that when borrowing fire, the negative terminal of the rescue vehicle must be connected to the metal part of the engine room of the non-electric vehicle. If it is directly connected with the negative terminal of the battery, sparks will be generated. Secondly, the jumper cable is connected. When the positive and negative terminals are not in contact, sparks may also occur.
Again, do not get close to the battery while charging. Because the battery liquid contains dilute sulfuric acid and may be sprayed, if it is sprayed on the eyes and skin, it will cause damage. If the liquid sticks to the body, rinse it with plenty of water and go to the hospital for treatment. Finally, when connecting or removing the jumper cable Keep away from fans, belts, etc. as far as possible to avoid accidents caused by the involvement of your hands or clothes.
After borrowing the fire, you should also try to drive at a constant speed (such as highway speed) for at least 20-30 minutes to fully charge the battery.
Finally, experts remind everyone that if the car is not used for a long time, the car should be fully charged. At the same time, the car is started every other month, and the medium speed runs for about 20 minutes. Otherwise, the placement time is too long and it will be difficult to start. And should pay attention to the service life of the battery, generally about 4 years.
