The battery is the power of the car，It is mainly used to power the car starter and various electricity equipment during startup，It belongs to the start -up type battery。Current，Basically used on the car is a lead -acid battery，Using dilute sulfuric acid as an electrolyte，The active substances participating in electrochemical reactions on the pole plate are lead dioxide and lead。

In order to meet the needs of startup and electric equipment，When replacing the new battery，The capacity and rated value of the new battery must not be lower than the original battery used，And the size of the battery replaced must also be installed。At present, there are many brands on the market，Follow XSjiaoliu，More and more car knowledge knows it early。Mainly there are VARTA VARTA (former Delphi)、Acdelco、Panasonic (Panasonic)、sail、Unified、GS、 Original imported Korean Rockets、Tang Qian, etc.。The batteries produced by manufacturers also have different labels。

The models of the lead battery for automobiles are named after certain standards，The battery model used in the domestic market is mainly in accordance with national standards and Japanese standards、Named by German standards and US standards。

Taking a battery with a model of 6-QAW-54A as an example，Explanation as follows:
1.6 means consisting of 6 single batteries，Each single battery voltage is 2V，that is, the rated voltage is 12V;

2.q indicates the purpose of the battery，Q is a battery for the start of the car、M is a battery for motorcycles、JC is a battery for ships、HK is a battery for aviation、seabet logind means a battery for electric vehicles、f represents a valve -controlled battery;

3.A and W represent the type of battery，A means a dry lotus battery，w means a maintenance -free battery，If it does not standard, it means ordinary battery;

4.54 indicates that the rated capacity of the battery is 54AH (the battery that is sufficient，Downs the current at a 20H rate at a normal temperature and discharge the electricity output from the 2h battery);

5. Corner A represents the first improvement of the original product，Name after adding an angle bid B to indicate the second improvement，Push in order。
Note: ① Add D after the model to indicate that the low temperature startup performance is good，such as 6-QA-110D。
   ② After the model, add HD to indicate a high vibration type.
   ③ After the model, add DF to indicate low -temperature reflection，such as 6-QA-165DF。

In 1979，Japanese standard battery models are represented by Nippon of Japan，The number behind is the size of the battery slot，Use the rated capacity of the battery to represent，such as NS40ZL:

1. n means the Japanese JIS standard;
2. s means miniaturization, that is, the actual capacity ratio 40 ah small, 36AH;
3. Z means that there is a better start -up discharge performance at the same size，s indicates that the polar pile terminal is thicker than the same capacity battery，such as NS60SL;
Note: Generally speaking, there are different diameters of the positive and negative poles of the battery，To avoid the battery stretch polarity。The diameter of the cone -shaped terminal is shown in Table 1。
4. L means the positive pillar is at the left end、r means the positive pole pile is at the right end，such as NS70R。(Note: From the direction of the polar pile away from the battery)

Model 544 34 battery storage as an example, explaining as follows:
1. Start 5 indicates that the rated battery capacity is below 100AH; the beginning 6 indicates that the battery seabet appcapacity is between 100AH ​​and 200AH; the start 7 indicates that the rated capacity of the battery is above 200AH。For example 544 34 The rated capacity of the battery is 44AH; 610 17mf battery rated capacity is 110 ah; 700 27 The rated capacity of the battery is 200 AH.
2. After the capacity, two digits indicate the battery size group number。Take a few examples，As shown in Table 4。
3.mf indicates the maintenance -free type.

Model 58 430 (12V 430A 80min) battery storage as an example, explaining as follows:

1.58 indicates the size group number of the battery, as shown in Table 5.
2.430 means that the cold start current is 430A.
3.80min indicates that the battery reserve capacity is 80min。   
4. Standard batteries in the United States can also be expressed like this: 78-600，78 means the battery size group number，600 indicates that the cold start current is 600A。
In the maintenance of a car，Maintenance of batteries is also very important，If you develop bad habits，will shorten the service life of the battery or cause damage。The life of the battery is generally 2 to 3 years。If the user installs some of the original electrical appliances，such as a subwoofer, etc.，will cause excessive use of batteries。

Now now，More and more electric equipment on the car，So，When the owner uses these electric devices，Try not to let the battery work overload。Take electric windows and sunroof as an example，The owner should complete its lifting and closure before the engine is turned off，Because if the engine is turned off，will stop generating electricity，At this time, the window will increase the load of the battery，It is easy to cause damage to the battery。

The same is true for the lights，If you want to turn off，No special necessity，It should be turned off first，Then turn off the fire，When starting the car at night, you should also turn on the headlights first，Know all inside the car。Try to minimize damage to batteries。If the battery work is made seabet ioif the engine stops working，Be sure to prevent batteries from losing electricity，Because if you lose electricity, it is easy to cause damage to the battery，If the loss is serious，The battery will be scrapped in advance。(The content of the article comes from the Internet，If you involve the copyright, please contact delete)
