This auxiliary battery powers onboard electronics, comfort functions, and the ECO Start/Stop system, especially when the main battery is under high load.

📌 Notes:

• This auxiliary battery does not crank the engine; it supports onboard electronics and the Start/Stop system when the main battery is busy or voltage drops.

• Always confirm the battery part number (like A0009829308 or A0009829608) before replacement.

• Some imports, especially ex-Japan and ex-UK units, often include ECO Start/Stop-equipped trims needing this auxiliary battery.
