- Exide AGM12-9: the same capacity, 35 A more cranking power, the same dimensions, AGM technology.

## Before ordering the 12N9-4B-1, check this

- Check the EN amps on your battery: if it says 85 A or less, the 12N9-4B-1 covers your engine.
- With 9 Ah, the 12N9-4B-1 replaces an original battery of that capacity or slightly less.
- Polarity of the 12N9-4B-1: positive terminal on the left (if yours has it on the other side, the cables will not reach).
