In 1979, Japanese Jis Standard Battery models were represented by the N of Nippon, followed by the size of the cell slot, expressed in terms close to the rated capacity of the battery, such as NS40ZL:
1.N stands for JIS Standard;
2 . S represents miniaturization, that is, the actual capacity is 36Ah, smaller than 40 Ah; .
3. Z indicates better starting discharge performance under the same size, S indicates that the pole pile terminal is thicker than the battery with the same capacity, such as NS60SL; Note: Generally speaking, the positive electrode and the negative electrode of the battery have different diameters to avoid reversing the polarity of the battery.
4. L represents the positive pole at the left end and R represents the positive pole pile at the right end, such as NS70R. (Note: From the direction of far away from the battery pole pile) to 1982, the Japanese Jis Standard battery models in accordance with the new standard, such as 38B20L(equivalent to NS40ZL): 38 indicates the performance parameter of the battery. The larger the number, the more power the battery can store.
5. B indicates the width and height of the battery. The width and height combination of the battery is represented by one of the eight letters (A to H). The closer the character is to H, the greater the width and height of the battery.
6. 20 Indicates that the length of the battery is about 20cm.
7. L indicates the position of the positive terminal. When looking away from the battery pole, the positive terminal is marked R on the right end and L on the left end.
