What is JIS on a Battery?
JIS stands for Japanese Industrial Standards, which define the specifications for various products, including automotive batteries. A JIS battery is designed based on these standards, ensuring compatibility with Japanese and other Asian vehicles.
Unlike BCI batteries, which follow North American sizing, JIS batteries use a unique numbering and lettering system to indicate their capacity, dimensions, and terminal arrangement. These batteries are commonly found in Toyota, Honda, Nissan, Mitsubishi, Mazda, and other Asian vehicles.
For example, a JIS battery code like 55D23L can be broken down as:
- 
55 – Performance rating (higher means more capacity) 
- 
D – Case size and shape 
- 
23 – Battery length in centimeters 
- 
L – Terminal position (L for left, R for right) 
Choosing the correct JIS MF battery ensures optimal performance, easy installation, and proper terminal connections for your vehicle.
