Peugeot 2008 Sos Battery Replacement -

Replacing the SOS backup battery in a Peugeot 2008 is a specialized task because this battery is separate from the main 12V car battery and is typically housed within the autonomous telematics box. Key Replacement Details

Important Notes:

• The Peugeot 2008 first generation uses this battery. Some later models use a different integrated battery (check with dealer or service manual).
• After replacement, a diagnostic tool (Diagbox) may be needed to clear a “Backup battery low” fault stored in the telematic unit.
• If soldering is not for you, buy a pre-asserved SOS module from a breaker (but battery may be old too).

6. Important Warnings

• ⚠️ Do not ignore the warning – the system may drain your main car battery if the SOS battery is shorted.
• ⚠️ Do not use a standard Li-ion 18650 – wrong voltage or capacity can damage the module.
• ⚠️ After replacement, the system may need a diagnostic reset (Diagbox or OBD2 tool) – though many Peugeot 2008s auto-reset after a few drive cycles.
