Meta Mechanics recently completed an auxiliary battery replacement for a Range Rover Autobiography in Dubai. During this service, our expert technicians carefully inspected the vehicle’s secondary electrical systems and identified several issues that were affecting performance. Auxiliary batteries are crucial for managing power to non-essential systems, such as the infotainment, start/stop functions, and comfort features. Below are the key issues found and the solutions provided.
Issues Identified:
- Depleted Auxiliary Battery
- Problem: The auxiliary battery had become significantly depleted, impacting power supply to secondary systems like the start/stop function, infotainment system, and climate control. This caused irregular system behavior and occasional failures.
- Solution: We replaced the depleted auxiliary battery with a high-quality, manufacturer-approved unit. This restored power to all auxiliary systems, ensuring smooth operation and improving vehicle efficiency.
- Corroded Battery Terminals
- Problem: The battery terminals were corroded, which can prevent a proper connection and result in fluctuating power delivery to the vehicle’s auxiliary systems. This often causes malfunctioning of non-essential features.
- Solution: We cleaned and treated the corroded terminals with anti-corrosion chemicals, ensuring a secure and reliable connection to the auxiliary battery and preventing future corrosion.
- Faulty Auxiliary Battery Charging Circuit
- Problem: The charging system responsible for recharging the auxiliary battery while the vehicle is running was malfunctioning. This issue prevented the battery from receiving the proper charge, causing it to drain quickly and reducing overall battery lifespan.
- Solution: Our technicians inspected and repaired the charging circuit, ensuring the auxiliary battery receives the correct charge while the engine is running, enhancing its performance and extending its life.
- Parasitic Electrical Drain
- Problem: A parasitic electrical drain was identified, which was causing the auxiliary battery to lose charge even when the vehicle was parked, leading to premature battery depletion.
- Solution: We identified and fixed the source of the parasitic drain, ensuring that the new auxiliary battery remains charged when the vehicle is not in use, preventing unnecessary discharge and improving the battery’s reliability.
- Battery Management System (BMS) Calibration Issues
- Problem: The Battery Management System (BMS) was not properly calibrated, leading to inaccurate readings and inefficient charging/discharging cycles for the auxiliary battery.
- Solution: After installing the new auxiliary battery, we recalibrated the BMS to ensure it properly monitors the battery’s charge and discharge cycles, preventing overcharging or deep discharging and optimizing battery performance.
