Looking at the battery model requires us to understand the meaning of the battery model. The battery model consists of three parts, which are separated by dashes:
The first part is the number of single cell batteries in series, which is expressed in Arabic numerals. Generally, there are six cells in a 12V battery, and the number "6" indicates that there are three cells in a 6V battery, and the number "3" indicates that there are three cells in a 6V battery.
The second part is the battery type and characteristics, which are usually represented by the first letter of Chinese characters. Generally, the first letter indicates the purpose of the battery, such as Q for automobile starting, M for motorcycle, JC for marine, HK for aviation, D for electric vehicle, F for valve regulated battery, the second letter indicates the characteristics of the battery, such as A - for dry charge, H - for wet charge, W - for maintenance free, S - for less maintenance M refers to fully sealed type, J refers to colloid electrolyte, etc. If there is no mark, it refers to ordinary battery.
The third part is the rated capacity of the battery, which is often referred to as the size of the battery capacity. Its unit is A? H (ampere hour), generally not marked. We can identify batteries mainly by this number.
