Mercedes-Benz Trucks has introduced a new reworked high-voltage battery for its electric commercial vehicles, offering a resource-efficient alternative to purchasing new units. The CB400 battery, now available for first-generation eActros 300/400 and eEconic models, is part of the company’s broader effort to promote a circular economy and reduce carbon emissions.
The CB400 “Genuine Reworked Battery” is designed to match the quality and functionality of new batteries, while reducing environmental impact and cost for customers. According to Mercedes-Benz Trucks, the remanufactured units undergo full safety and performance checks and are covered under the brand’s original parts warranty.
“With the CB400 reworked concept, we offer our customers a cost-efficient and sustainable solution that reuses high-quality components, thereby reducing resource consumption and greenhouse gas emissions — all while maintaining consistently high quality,” said Christian Vrbek, Team Leader Remanufacturing Zero Emission Vehicles in Aftersales at Daimler Truck.
The battery refurbishment process is carried out at the company’s Competence Center for Emission-Free Mobility (KEM) in Mannheim. Used CB400 batteries are retrieved from customer vehicles, disassembled, cleaned, and upgraded to the latest series standards before re-entering service. Mercedes-Benz estimates that using reworked batteries can lower CO₂ emissions by approximately one-third compared to manufacturing new ones.
The introduction of the CB400 exchange battery comes as production of the eActros 300/400 series nears its end. However, Mercedes-Benz Trucks notes that “the demand for reliable and cost-effective spare parts remains,” underscoring the ongoing need for high-quality battery replacements even as the product line transitions.
Insights from the CB400 programme are already being applied to the development of next-generation batteries, such as the upcoming CEB500 for the eActros 600, further cementing Mercedes-Benz Trucks’ commitment to sustainable innovation in commercial electric mobility.
