Purpose and compatibility

The presented 48V starter battery has been designed for Mercedes C-Class, E-Class, E-Class Coupe, and GLC models from the W205, W213, W238, and W253 series equipped with a 48-volt system. As an item from the Batteries category, it works with the starting system and powertrain support systems typical of modern mild-hybrid units. Thanks to its factory origin, compliance with charging parameters, alternator operating characteristics, and energy management strategies in Mercedes control units is maintained. This helps avoid communication issues within the vehicle's network and reduces the risk of diagnostic errors.

Technical and functional characteristics

The 48V starter battery in this version plays a key role in powering the engine start system and stabilizing voltage in the 48V circuit. The design, adapted to the manufacturer's requirements, enables:

• sufficiently high current efficiency during startup,
• stable voltage maintenance for 48V consumers,
• cooperation with recuperation and energy recovery systems,
• proper integration with the factory energy management system. Such a match is particularly important in vehicles with extensive electronics, where the consistency of battery parameters with control unit software affects the reliability of the entire powertrain.

Condition, origin, and benefits of choosing a used part

The offered battery belongs to the group of used parts, which allows for a significant reduction in vehicle maintenance costs while maintaining the manufacturer's original specifications. Choosing this solution is particularly beneficial in the case of advanced 48V systems, where the use of random replacements can lead to system malfunctions. An original component from disassembly also means a lower risk of dimensional incompatibility or mounting problems. As a result, installation is smoother, and the battery can be integrated into the system without the need to modify wiring harnesses or brackets.

Professional application and service aspects

The 48V starter battery in Mercedes vehicles requires proper service handling, including the correct procedure for disconnecting and connecting to the system, as well as potential adaptation in the diagnostic system. For this reason, it is an element particularly recommended for workshops specializing in the Mercedes brand and users working with professional service centers. A properly selected battery from this group allows you to:

• maintain the stability of the starting system,
• preserve the correct operation of comfort and safety systems,
• minimize the risk of unplanned vehicle downtime.
