Description
Negative battery terminal cable for Citroën and Peugeot vehicles.
This negative battery terminal cable (OE 9676828980) is designed for grounding the electrical system on selected Citroën and Peugeot models. Durable and built to handle high cranking currents, it restores a low-resistance path between the battery negative pole and vehicle chassis/engine block. Commonly searched by its product code 9676828980, this part is a practical replacement for worn or corroded ground connections and is aimed at professional technicians and experienced DIY mechanics.
Technical Information
- Manufacturer: Stellantis
- Model: Citroën C5 (X7); Peugeot 508
- Product Codes: 9676828980
- Other Numbers: N/A
Application And Function
The negative battery cable provides the main return path for electrical current from the vehicle’s electrical system back to the battery. It ensures stable ground reference for the starter motor, charging system and body electronics. A healthy, low-resistance ground is essential for reliable engine starting and for preventing intermittent faults in electronic modules, sensors and vehicle comfort systems.
Replacement And Removal
Replacing the negative battery cable is usually straightforward for a trained technician or competent DIYer. Typical steps:
- Ensure the ignition is off and all loads are switched off.
- Disconnect the battery negative terminal first to avoid short circuits.
- Loosen and remove the clamp or bolt securing the old cable at the battery and at the chassis/engine ground point.
- Remove the old cable, note routing and any retaining clips, and fit the new cable following the same route.
- Secure connections firmly, clean mating surfaces if required, and apply appropriate anti-corrosion compound where recommended.
- Reconnect the battery (negative last if you disconnected the positive earlier), then verify charging and starting performance.
Installation Recommendations
- Use the correct OE code (9676828980) to ensure fit and routing match the original part.
- Always disconnect the battery before starting work and follow vehicle manufacturer safety procedures.
- Inspect terminal faces and ground points for corrosion or paint; clean to bare metal for best contact.
- Replace any corroded clamps or fasteners and secure the cable with original clips to avoid chafing against hot or moving parts.
- After installation, check for excessive voltage drop during cranking and verify proper charging system voltage at idle.
- If unsure about access or routing on a specific model, have the work performed by a professional workshop.
Why The Part Commonly Fails
Negative battery cables usually fail due to corrosion at the terminals or at chassis/engine ground points, mechanical fatigue from vibration, heat exposure, oil or coolant contamination, or damage from improper routing that causes chafing. Loss of tight contact or increased resistance leads to hard starting, dimming lights, intermittent electronic faults or fault codes. There is no fixed replacement interval; inspect the cable during regular servicing and replace if you find visible deterioration, high resistance or startup issues.
Notes For Buyers
Searches for this part are often performed using the OE number 9676828980. Confirm vehicle model compatibility with the listed models (Citroën C5 X7, Peugeot 508) before purchase and match routing and terminal types to the original cable on the vehicle.
