How to watch the model of the battery? Can a car can replace a larger specifications?

These numbers on the battery indicate the rated capacity of the battery. The so-called rated capacity is to continuously discharge the electricity battery in the average temperature of 30c, until the battery voltage is lowered to 10.5V, the capacity output by the battery.

Rated capacity is one of the design capacity and is one of the important indicators of testing battery performance. For example, 60 in 6-QA-60 is rated, which is from 3a current continuous discharge for 20 hours, and the battery voltage dropped to 10.5V.

About the starting battery used by the car, there is also a capacity of the capacity, but it is not marked on the battery. So what do we identify? This will we understand the meaning of the battery model. The model of the battery consists of three parts, and the part is separated by a broken number: the first part is the number of series single battery, indicating the Arab figures.

In general, there are six single-single batteries in 12V, indicated by numbers 6; three single-single batteries in the 6V battery, expressed with numbers 3. The second part is the type and characteristics of the battery, and the first letter of commonly used Chinese characters. Generally, the first letter represents the battery.

For example, Q is a car boot battery. M is a motorcycle battery. The JC is a battery of the ship.

The HK is the air battery. D represents the electric vehicle battery, f represents the valve control of the battery. The second letter represents the characteristics of the battery, such as A-represents dry load, H-means wet loading, W-means for maintenance, S- represents less maintenance, M represents full sealing, J-represents colloidal electrolyte Wait, if there is no label, it is a normal battery.

The third part is the rated capacity of the battery, which is the size of the battery capacity, its unit is a•H (amp. hour), generally not marked. We distinguish the battery and see this number.

Also some batches are also used in the back of the rated capacity, which represents the specific performance of the battery, such as G-means high-powered, S-represents the plastic housing, D-indicates that the low temperature start performance is good, and HD represents high-resistant vibration, DF means low temperature reverse etc. Have an example to say. For example, the battery meaning of the model 6-QAW-54A is as follows: 6 represents 6 gs, one is 2V, represents 12V; Q is starting type, A means dry charge, W is maintenance; 54 is a battery capacity 54ah; The corner A represents the first improvement to the original product.

Therefore, the battery is the first improved product of a start-type dry load that is 12V having a capacity of 68ah. The careful owner will find a problem, that is, the battery is getting smaller and smaller. If you continue to start a few engines, or listen to the sound in the same place, the battery's electricity is insufficient.

This is actually a reduction in the car enterprise, the large-capacity battery and small capacity battery difference is not small, and the car enterprise saves costs from this. So can we change a larger capacity battery? This is completely ok, replacing a big battery, there is no effect on generators and electrical equipment on the car, and will add their reliability. As long as the engine cabin is enlarged, you will change.

However, there are some models of battery management systems, generally do not allow replacement of battery specifications, if they are free to replace, there may be fault code, and even make the engine can't start. As everyone knows, good electric cars must have a good battery to ensure that the car's riding mileage, but some numbers on the battery, the alphabetic symbols make the owners to see, such as 6-dzm on the Tianneng battery. 20, what do you mean? Explanation of the instructions also look at a semi-solving.

In fact, the battery is used as the power of electric vehicles, which determines whether the car can start, how far is much, whether it is purchased or intended to buy electric cars, and understand that the battery model is quite necessary. Today, Xiaobian will give you a simple letter and number of the electric vehicle battery.
