General car batteries have a service life of 2-3 years，But many car owners have some improper car habits，Causing the battery to run out of power quickly。Today, let’s take a closer look at these bad habits and some precautions for battery maintenance。

First of all, you need to check where the headlight gear is，If it is a width indicator light block，Then it will be miserable，It will stay on until you notice or the battery runs out of power。If it is in the headlight block，For example, low beam and high beam are blocked，The headlights will automatically turn off after you remove the key，But it must be shut down in time before starting in the morning。If the gear is in AUTO, then you don’t need to worry about it，The headlights will automatically turn off when the key is removed。

Some car owners will not turn off the air conditioner before turning off the engine，This seemingly harmless little move，Very damaging to the battery。Because when the vehicle starts，The air conditioning system will also start automatically，Start work。The instantaneous power load of the vehicle is very high at this time，It will damage the car battery in the long run。

Continuing to use electricity after turning off the flame includes many situations，For example, using electrical seabet appappliances in the car for a long time after turning off the engine，Forgot to turn off the car lights, etc.。The car’s generator is not working at this time，The battery is in "dry consumption" state without charging，The reduction of its electric capacity may cause the vehicle to be unable to start，And excessive discharge will cause great damage to the battery itself。

For newbies，Flameout is common，The editor recommends that each time you start the engine, it should not exceed 3 seconds。If it fails the first time，Don’t rush to start repeatedly at this time。Continuously starting the motor will definitely cause excessive discharge of the battery and damage it。So the time interval between restarts should exceed 5 seconds。

Some car owners are obsessed with music，Frequently install high-power speakers。Whether it is while driving，Still idling and waiting for someone，The sound must not be stopped。Listening to high-power audio when the vehicle is not started，It will bring extremely high load to the battery，Severe damage to the battery。

Many car owners want to improve the convenience and comfort of using their cars，I often use this power interface to connect many external devices，such as GPS、Driving recorder、Air purifier, etc.。

Easy additional electrical equipment itself increases the burden on the battery，The cigarette lighter of some models is still in the power-on mode when the flame is turned off，If the external device is not unplugged, it will consume battery power，Loss battery。

Panel、Dust on the stigma、Oil、Wipe clean white powder and other dirt that may easily cause leakage。Frequently scrub the stigma of the battery，Not only will the white etching powder Seabetnot accumulate on it，And the battery life will be longer than expected。

Cannot leave the vehicle without running for a long time, which will cause difficulty in starting。Even if the vehicle is not used，Also open every few days，Let the battery recharge，Ensure the battery is always fully charged。But the car is often driven for short distances，Open, stop, stop，Will cause the car battery to be undercharged for a long time，Shorten service life。Driving on the highway at a steady speed for 20-30 minutes，Can give the car battery enough time to charge。

If you find that the vehicle is more difficult to start the next day than usual，It is possible that this is also due to insufficient battery power, making it difficult to start。Especially in the cold winter，This phenomenon is likely to be mistaken by most people as "difficulties in cold starting in winter"，But in fact, this may also be a precursor to battery failure。

There is another situation where the headlights will dim inexplicably，This may also be a precursor to battery failure。When the vehicle is idling or low speed，When the power requirements of the electrical equipment on the vehicle cannot be fully met，The battery will assist the power generation system to power the electrical equipment in the car;But if the battery is insufficient at this time，Unable to provide auxiliary power supply，This "headlights dimming inexplicably" situation will occur。

In order to maintain the best performance of the battery，It is best to go to the 4S store to check the battery every six months，Look at the power storage capacity。General battery life is about 2-3 years，If taken good care of, it can last up to 4 years。But the further you go, the shorter the time you need to check the battery。The car battery must not only provide power for starting the seabet myengine，Also supplies power to other electrical equipment。As a relatively fragile component，We should take better care of it。(The content of the article comes from the Internet，If copyright is involved, please contact us to delete)
