Question 2: How to judge the battery capacity of a car? To judge the charge of the battery, we must first listen to the sound when the starter starts. If it doesn't sound bad, there are two situations. One is that the battery is low, and the other is to maintain the starter. The battery on the dashboard mainly depends on whether the generator generates electricity after the car starts. When it is on, it means that the generator is not generating electricity and needs maintenance. Generally, you can't see the battery charge.
Question 3: How to check the model of car battery 1? National standard battery.
Taking the battery model 6-QAW-54a as an example, the explanation is as follows:

Taking the battery model 58 430( 12V 430A 80min) as an example, the explanation is as follows:
1.58 indicates the battery size group number, as shown in Table 5.
2.430 indicates that the cold start current is 430A.
3.80 minutes means that the storage capacity of the battery is 80 minutes.
Note: ① Cold start current (CCA): the minimum current that can be obtained in a specific sense at-17.8℃ and -28.9℃. This index relates the starting ability of the battery with important variables such as engine displacement, compression ratio, temperature, starting time, technical status of the engine and electrical system, and the minimum working voltage for starting and ignition. Refers to the minimum current that can be provided by cold start when the terminal voltage of 12V battery drops to 7.2V within 30s after it is fully charged. & gt
Question 5: How to judge the battery capacity 1 of a car? Test the battery capacity with voltmeter and load.
It is difficult to accurately check whether the storage capacity of the battery is enough only by using the voltage block of voltmeter or multimeter under no load. When measuring the voltage alone, the current consumption is very small, so there will be no big voltage drop inside the battery, so the display voltage is not low. However, if a considerable load is added, such as turning on the headlights (load current 10 ~ 15A) and pressing the horn (load current 6 ~ 12A), the battery will dim the lights and make the horn hoarse, thus showing insufficient power storage.
The correct and reliable detection method is to connect a starter in the car to detect the battery voltage. The steps are as follows: at the normal temperature of the engine, connect the voltmeter to the positive and negative poles of the battery, and pull out the fuel injector wire to make the engine unable to start. Start the engine, run continuously for 5 ~ 10 seconds, and observe the degree of voltmeter. When the starter is well connected to the line, the battery voltage of 12V is above 9.6V, indicating that the battery technology is in good condition. If the voltage is lower than the above value, it means that the battery is in a state of power shortage and its power storage capacity is insufficient.
Second, use a hydrometer to detect the storage capacity of the battery.
It is also a common method to detect the storage capacity of battery with hydrometer. Generally speaking, at 20℃, the standard electrolyte specific gravity of a fully charged battery is1.25 ~1.29 kg/L; If the specific gravity of the electrolyte at 20℃ is less than the above value and greater than 1.06kg/l, the storage capacity of the battery is insufficient and it needs to be charged. If the specific gravity of the electrolyte at 20℃ is below 1.06kg/l, it means that the battery has been completely discharged or damaged. According to this principle, the storage capacity of the battery can be known by measuring the specific gravity of the battery electrolyte with a hydrometer, and then the condition of the battery can be judged.
Third, use the battery detector to detect the storage capacity of the battery.
In the daily maintenance and repair, it is still necessary to use the battery detector to truly detect the storage capacity of the battery quickly and accurately. When in use, connect the battery detector to the battery 10 ~ 15 seconds, and keep the voltage at10.5 ~11.6v, indicating that the capacity is sufficient and the battery is trouble-free; The voltage is kept at 9.6V ~ 10.5V, indicating that the capacity is insufficient and the battery is trouble-free; If the voltage drops below 9.6V, the capacity is seriously insufficient or the battery is faulty. The above is just a simple battery detector, which can only measure the battery voltage in the state of large current discharge and roughly judge the storage capacity of the battery. At present, the advanced battery detector can accurately measure cold start current (CCA) besides starting discharge.
Four. conclusion
To sum up, the capacity detection methods of automobile batteries include: voltage blocking and load detection of voltmeter or multimeter, capacity detection of hydrometer, and capacity detection of special battery detector.
Question 6: How to look at the size of the car battery ... Ah stands for amperage ~ The greater the battery amperage, the larger the battery ~ for example, 60AH, this is a 60A battery car. Ask the car master if you have any questions. 4S shop professional technician, 10 minutes to solve.
Question 7: How to judge whether the car battery can still be used? The design life of the battery is 27 months. Almost all batteries used in automobiles are lead-acid batteries. The biggest feature of lead-acid battery is that with the use of the battery, the electrode plate is gradually aging, and when the capacity is reduced to 80% of its rated capacity, it is possible to "dive". At this time, although the car battery may still provide some energy, it may be scrapped at any time. If this time limit is reached or near, and the following phenomena occur, it is recommended to replace it:
You can turn on the headlights to check. If the light is white, the battery is normal; If the light is red and black, it means there is not enough power. Turn on the starter. If the speed is normal, the light is slightly dim, but there is still enough brightness, indicating that the battery is good and fully charged. If the starter is weak and the lights dim, it means that the battery is over-discharged, and it should be charged, maintained or replaced immediately. When the car is not in use, the sound of the horn is relatively low, indicating that the battery is weak, so be careful.
It's best to go to the repair shop and use the car battery detector or car battery analyzer to detect and judge the aging and scrapping of the battery!
Question 8: How to judge whether the car battery needs to be replaced? You can turn on the headlights to check. If the light is white, the battery is normal; If the light is red and black, it means there is not enough power. Turn on the starter. If the speed is normal, the light is slightly dim, but there is still enough brightness, indicating that the battery is good and fully charged. If the starter is weak and the lights dim, it means that the battery is over-discharged, and it should be charged, maintained or replaced immediately. When the car is not in use, the sound of the horn is relatively low, indicating that the battery is weak, so be careful. 2. How long is the life of a car battery? What are the factors that affect battery life? How to use it to extend the battery life? The design life of the battery is 27 months, which is more economical for general family cars. Many batteries in new cars last for 3-4 years, but they must be replaced once, usually about 2 years. Taxis are more expensive. Single bus can be used for one year, and double bus can be used for about 8- 10 months. There are several factors that affect the service life of the battery: car condition, road condition and driver's habits. Generally, the newer the car, the more energy-saving the battery. Because the motor is easy to use, it saves batteries, and the generator can be fully charged. After the car is old, especially after replacing two large motor generators, the difference between the original products and the refurbished products in the market is huge, so it is easy for the owner not to change the original parts, and then the battery is more likely to break down. Off-road batteries are often easy to break down, and car batteries have a technical index to express their anti-vibration performance! If the standard battery works in a bad environment and often vibrates, of course it is not good. The battery is easy to be damaged by novice drivers, because novice drivers generally lack common knowledge of vehicle use. 3. How to identify the authenticity of the battery?
