## Summary

## Fits

No vehicle list: check the specification against the vehicle or the handbook.

## Why this one

- **Backup duty**: Keeps electronics and safety systems powered while the starter battery cranks.
- **Vent and flame arrestor**: EN-compliant degassing vent with a flame arrestor for safe gas release.
- **Maintenance-free**: No topping up needed in service.
- **ETN 509106013**: Short code AUX9, case YTX9, for a quick match to the fitted battery.

## On the job

### What it does

Many modern cars carry a small second battery next to the starter battery. It keeps voltage steady for electronics and comfort functions while the engine cranks, stretches start-stop phases, or backs up safety systems. The AUX9 is an AGM unit in the compact YTX9 case, 151 x 87 x 106 mm, with an EN-compliant vent and flame arrestor.

### Before you fit it

Auxiliary batteries vary a lot between makes, so compare dimensions, capacity, terminal layout and hold-down with the original before ordering; a few millimetres of height matter in a tight bracket. When the auxiliary battery fails, test the main battery and charging system too, as they usually age together.
