Description
Battery Charge Level Unit for Citroën and Peugeot Vehicles
The Battery Charge Level Unit (part number 9676600080) monitors the battery state of charge and communicates battery condition to the vehicle network. Designed for Citroën and Peugeot passenger cars, this module helps optimize charging strategy, manage alternator load and support energy-saving functions in modern PSA electrical systems. The unit is a direct-fit replacement for vehicles that use the 9676600080 reference and is intended for professional fitment or experienced DIY mechanics familiar with vehicle electrics.
Function And Benefits
This unit continuously measures battery voltage, current flow and charge level parameters, providing the engine management and body control systems with accurate battery state information. Proper operation ensures reliable engine starts, correct charging regulation by the alternator and stable operation of stop/start and comfort systems. Replacing a faulty unit restores accurate battery data, reduces risk of unintended electrical faults and improves charging efficiency.
Compatibility And Typical Fitment
Fits Citroën and Peugeot vehicles using the OEM reference 9676600080. Commonly fitted to mid-size PSA passenger cars; an example application is Peugeot 508. Always verify the product code against the vehicle’s parts list before purchase. This unit is aimed at mechanics and competent DIY enthusiasts servicing PSA electrical systems.
How Replacement Is Performed
- Prepare Vehicle: Park on a level surface, engage parking brake and follow safety procedures.
- Disconnect Battery: Always disconnect the negative battery terminal before starting to avoid electrical damage.
- Access Unit: Remove relevant trim or fuse box cover to access the module (location depends on model).
- Disconnect Connectors: Carefully release electrical connectors and any securing clips or screws.
- Install New Unit: Fit the replacement unit, secure fasteners and reconnect electrical connectors.
- Reconnection And Checks: Reconnect the battery, then perform system checks and a charging system test. On some vehicles a diagnostic reinitialization or adaptation may be required to register the new unit.

Installation Recommendations
Disconnect the battery before any work and wait a few minutes to allow capacitors to discharge. Use appropriate hand tools and avoid pulling on wiring. Check connector pins and harness for corrosion or damage and replace any compromised clips or seals. After fitting, verify battery health and alternator charging with a suitable multimeter or diagnostic tool. If vehicle systems indicate faults after replacement, perform a full diagnostic scan and clear codes as needed.
Why This Part Fails Most Often
Failures are usually caused by long-term exposure to heat, vibration, water ingress or corrosion at connector points. Repeated deep discharges, poor battery condition or irregular charging can stress the unit’s electronics. Physical damage during previous repairs or loose electrical connections may also lead to incorrect battery state readings and premature failure.
Notes For Mechanics And DIYers
This is a precision electronic module. Confirm the OEM code 9676600080 before ordering. Test the battery and charging system before replacing the unit to avoid replacing a module when the root cause is the battery or alternator. For vehicles requiring coding or adaptation after fitment, use appropriate diagnostic equipment and follow manufacturer procedures.
