Mercedes-Benz is preparing a high-voltage battery replacement programme for certain electric models in Germany after earlier software fixes proved insufficient, according to reports. The move follows global recall actions affecting the Mercedes-Benz EQA and Mercedes-Benz EQB, which have already seen battery replacements in North America and China.
Information first reported by the Mercedes-focused site mb.passion indicates that workshops were notified of an upcoming replacement campaign for the EQA 250+ and EQB 250+ variants. These models use a 70.5 kWh battery pack containing cells supplied by Farasis Energy and mounted beneath the vehicle floor.

Under certain conditions, the cells may develop internal short circuits that could lead to fires. Mercedes initially addressed the issue through a battery management software update, but the measure reduced usable energy capacity and charging performance. Consumer complaints followed, including legal action alleging the vehicles no longer met advertised specifications after the update.
According to the report, the software fix was considered an interim measure rather than a permanent solution. The planned remedy involves complete replacement of the battery pack, removing the affected cells. The process is expected to require roughly eight hours of labor per vehicle. Details about the supplier, capacity, or performance of the replacement batteries have not yet been disclosed.

The programme has reportedly been communicated internally to dealerships, with a formal recall expected to be announced by Germany’s Kraftfahrt-Bundesamt (Federal Motor Transport Authority). Once approved, affected owners would receive official notification and scheduling information.
The staggered response has drawn criticism from some customers, as full battery replacements were already offered in other regions while German owners initially received only the software update. Replacing the battery packs is expected not only to restore original performance levels but also to address safety concerns and potentially improve resale values.
