## Long car batteries with JIS codes

The Long car range is built to the Japanese JIS standard, the format used by many cars of Asian origin. We list 50 Long car batteries, mainly in B24 and D23 cases (8 each), D26 (6) and D31 (4). Capacities in this section go from small units of a few amp hours up to 210 Ah, with popular car references of 45 and 50 Ah.

## How to read a JIS code

Take **46B24L** as an example: 46 is the performance rank, B the width and height group, 24 the approximate length in centimetres and L the side of the positive terminal. Other suffixes add detail:
- **MF** means maintenance-free, as in the 46B24L-MF.
- **(S)** indicates thin terminal posts, as in the 46B24L(S).
- **L / R** mark opposite polarity: 48D26L and 48D26R (50 Ah), 50D20L and 50D20R (50 Ah).

## Frequently asked questions

### Can I swap a 46B24L for a 46B24R?

Not normally: the terminals are on opposite sides and the cables may not reach. Keep the same letter as your original.

### Why do some Long batteries have (S) in the code?

They have thinner terminal posts used by some Asian cars; your clamps will not grip standard thick posts properly, or vice versa.
