What does the 55d23l battery model mean? Can 55d23l be replaced with 65d23l?

Model 55d23l is a standard Japanese battery specification, 55 represents the ampere hours of the battery, d represents the width * height of the battery, 23 represents the front length of the battery 23 cm, and l represents the positive pole of the battery on the left. Vehicles that previously used 55d23l batteries can replace 65d23l batteries. There is no difference between the two except that the cold start current of 65d23l is slightly larger than that of 55d23l.

In addition, take the battery of 6-QAW-54a as an example: 6 refers to a battery composed of 6 single cells. The rated voltage of each battery is 2V, which adds up to a battery of 12V; Q refers to the battery of the battery. Uses, where Q represents the battery used for starting the car; A refers to the dry-charged battery; W refers to the maintenance-free battery; 54 refers to the rated capacity of the battery is 55Ah; the last corner mark a is for the original product The first improvement, and so on, b is the second improvement.

The working principle of the battery is that the lead plate filled with spongy lead is used as the negative electrode, the lead plate filled with lead dioxide is used as the positive electrode, and 22-28% dilute sulfuric acid is used as the electrolyte; when charging, electrical energy is converted into chemical energy, and when discharging It can be converted back into electric energy, and when the battery is discharged, the oxidation reaction that occurs on the negative electrode of the metal lead is also oxidized to lead sulfate.
