Meta Mechanics recently completed an auxiliary battery replacement for a Range Rover SV in Dubai. The auxiliary battery plays a vital role in supporting the main battery by powering various electronic systems, including infotainment, climate control, and electrical components when the vehicle is turned off or the engine is idle. During this service, our technicians identified several key issues that could potentially affect the vehicle’s performance and overall electrical system. Below, we highlight the issues found and the solutions provided to restore optimal functionality.
Issues Identified:
- Depleted Auxiliary Battery
- Problem: The auxiliary battery had significantly lost its charge retention, which led to issues such as erratic behavior in electrical systems like the infotainment, lighting, and comfort settings. It also contributed to increased strain on the main battery, which had to compensate for the lack of power from the auxiliary unit.
- Solution: We replaced the depleted auxiliary battery with a high-performance, manufacturer-approved unit. This ensures that the electrical systems receive consistent and reliable power, alleviating the strain on the main battery and improving overall vehicle performance.
- Corroded Battery Terminals
- Problem: Corrosion around the battery terminals was causing poor electrical connections. This can result in intermittent electrical failures, including difficulty powering up the vehicle’s interior electronics and inefficient charging.
- Solution: Our team cleaned and treated the corroded battery terminals with anti-corrosion agents, ensuring a secure, clean connection for optimal power flow to the auxiliary systems. This also prevents future corrosion issues and enhances the overall reliability of the battery connection.
- Faulty Battery Management System (BMS) Calibration
- Problem: The Battery Management System (BMS) was not properly calibrated to manage the auxiliary battery’s charge and discharge cycles. This could have caused overcharging or undercharging, leading to poor battery performance and a shortened lifespan.
- Solution: After replacing the battery, we recalibrated the BMS to accurately monitor and manage the auxiliary battery’s charge, ensuring efficient charging and maintaining its lifespan.
- Parasitic Drain from Electrical Components
- Problem: A parasitic electrical drain was found, where certain systems were continuing to draw power from the auxiliary battery even when the vehicle was turned off. This resulted in the battery losing charge prematurely, leading to the vehicle’s electrical components malfunctioning.
- Solution: We identified and resolved the source of the parasitic drain, ensuring that the auxiliary battery only powers the necessary systems and does not lose charge when the vehicle is not in use, extending the battery’s overall life.
- Inconsistent Power Supply to Electronic Systems
- Problem: The old auxiliary battery was unable to consistently provide power to certain electronic systems, causing intermittent failures of comfort features like climate control and the infotainment system, especially when the engine was off or in idle mode.
- Solution: By installing a new, high-performance auxiliary battery, we restored stable and reliable power to the vehicle’s electronic systems, ensuring that everything functions properly, whether the engine is running or the vehicle is idle.
