Many car owners cherish their cars very much，I feel heartbroken when I encounter a small bump，I don’t know，Some bad habits can also cause great damage to your car，Especially the battery that is easily overlooked!

Lead-acid battery used in general car batteries，Cycle life is basically 200-500 times，The service life is about 2-4 years，If used correctly，The service life of a battery can even be extended to 5-6 years，But if used improperly，Not only will the battery run out of power quickly，Life span will also be greatly reduced。Let’s break down these bad habits and some precautions for battery maintenance。

It depends on the position of your headlights，If it is the width indicator light，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 position，For example, low beam and high beam，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 have to worry about it，The headlights will automatically turn off when you remove the key。

Some car owners do not turn off the air conditioner before turning off the engine，This seemingly harmless little move，It seabet myactually hurts the battery。Although the air conditioner is turned on after turning off the engine, it does not cool down，Only natural wind，But it continues to consume battery power，It is very likely to cause battery loss;On the other hand，When the vehicle is next started，The air conditioner is also turned on at the same time，At this time, the instantaneous power load of the vehicle is relatively high，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 the stereo/radio for a long time、Connect car vacuum cleaner/purifier、Connect to air pump, etc.，It is recommended to unplug the interface after turning off the flame。

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

Every time you start the engine，The ignition time should not exceed 3 seconds，If the engine fails to start for the first time, do not ignite it frequently，Should start again after 15 seconds interval，Otherwise the battery frequently supplies strong current to the starter，will cause its own loss。

Then，Daily driving，How should we maintain our car battery?

Put the panel、Dust Seabeton 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 not accumulate on it，And the battery life will be longer than expected。

Vehicles cannot be parked for long periods of time，Will cause difficulty in launching。Even if the vehicle will not be used in the short term，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，Can cause the car battery to be undercharged for a long time，Shorten service life。And on the highway，Driving 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 than usual，It may be difficult to start due to insufficient battery power，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 3 years，With good maintenance, it can last more than 4 years，But seabet mythe further you go, the shorter the time you need to check the battery。(The content of the article comes from the Internet，If copyright is involved, please contact us to delete。)
