Mercedes Benz Battery Services

Mercedes Benz 48-volt battery repair, disassembly and charging

We provide advanced diagnostics and complete repair solutions for 48V battery systems.

Our service addresses software malfunctions — including those triggered after an impact (battery lockout) or occurring spontaneously — as well as SRS (Supplemental Restraint System) issues affecting the battery.

We perform both base and full recharging for low-voltage units (e.g., 5V in a 48V system) and repair the Battery Management System (BMS), which controls and balances the entire electrical assembly.

Frequently Asked Questions (FAQ)

1. What is the difference between HV battery maintenance and regeneration?

Preventive maintenance focuses on cleaning, balancing, and restoring the electrical contacts and cooling system to keep the battery in good condition. Regeneration, on the other hand, uses controlled charging and discharging cycles to reactivate the electrochemical capacity of the cells, helping the battery recover lost energy.

2. How does the reconditioning and repair process work for a Prius HV battery?

During reconditioning, the battery undergoes controlled charge and discharge cycles, similar to a “dialysis” process. Cells that recover are balanced and retained, while defective cells are replaced. This ensures the battery operates efficiently and safely without needing a complete replacement.

3. What does HV battery charging, balancing, and equalization involve?

This service ensures that all cells in the HV battery reach the same energy level. By correcting voltage differences through supervised charging and equalization, the process improves performance, prevents premature failures, and extends the overall lifespan of the battery.

4. When should a customer consider HV battery preventive maintenance and chemical cleaning?

Preventive maintenance is recommended when there are signs of overheating, reduced performance, or after several years of use. This service removes dust, hair, and debris from cooling pathways and chemically cleans electrical contacts, restoring conductivity and preventing thermal issues.

5. What are the benefits of supplying a remanufactured HV battery ready to install?

A remanufactured battery provides a quick and efficient solution by replacing the entire block. Each unit is tested, balanced, and validated before delivery, ensuring reliable performance. It offers a cost-effective alternative to a brand-new OEM battery and minimizes vehicle downtime.

6. How long does the reconditioning or regeneration process take?

The duration depends on the condition of the battery and the required service. On average, reconditioning or regeneration may take several days, as each cell is carefully tested, cycled, and balanced to ensure optimal performance.

7. Is there a warranty on EV Parts and Repair services?

Yes. All services, including reconditioning, regeneration, and remanufactured battery supply, are backed by a technical warranty that covers performance and reliability, providing peace of mind for both workshops and end customers.
