How to distinguish the battery


The battery is the power source of the car. It is mainly used to supply power to the car starter and various electrical equipment when it is started. It belongs to the starting battery. At present, lead-acid batteries are basically used in automobiles, that is, dilute sulfuric acid is used as the electrolyte, and the active substances participating in the electrochemical reaction on the plates are lead dioxide and lead.


 


In order to meet the needs of startup and electrical equipment, when replacing a new battery, the capacity and rating of the new battery must not be lower than the original battery, and the size of the replaced battery must also be properly installed. At present, there are many brands of batteries on the market, pay attention to xsjiaoliu, and know more and more complete car knowledge. There are mainly Varta VARTA (formerly Delphi), ACDELCO, Panasonic (Panasonic), Fengfan, Uni-President, GS, imported Korean Rocket, Yuasa, etc. The batteries produced by various manufacturers also have different labels.


 


The models of lead-acid batteries used in automobiles are named according to certain standards. The battery models used in the domestic market are mainly named according to national standards, Japanese standards, German standards and American standards.


 


Taking the battery with model 6-QAW-54a as an example, the description is as follows:


 


1.6 means that it consists of 6 single cells, and the voltage of each cell is 2V, that is, the rated voltage is 12V;


 


2. Q represents the use of the battery, Q is the battery for automobile starting, M is the battery for motorcycles, JC is the battery for ships, HK is the battery for aviation, D is the battery for electric vehicles, and F is the valve-regulated battery;


 


3. A and W represent the type of battery, A represents dry-charge battery, W represents maintenance-free battery, if not marked, it represents ordinary battery;


 


4.54 indicates that the rated capacity of the battery is 54Ah (a fully charged battery is discharged at room temperature with a discharge current of 20h at a rate of 20h);


 


5. The corner mark a represents the first improvement to the original product, and the corner mark b after the name indicates the second improvement, and so on.
