Mercedes-Benz details EV battery service, warranties and V2G plans

Mercedes-Benz has laid out how it plans to service and replace batteries in its electric cars. The company says its high-voltage packs are engineered to last for the vehicle’s lifetime under normal use, though it doesn’t specify an exact number of years. Warranty coverage varies by model: up to 10 years or 250,000 km for the EQS and EQE, and 8 years or 160,000 km for the EQA, EQB, EQC, and others.

If capacity falls below 70%, the brand offers repair or module replacement, and, when needed, installs a reconditioned pack. Mercedes is expanding deep-diagnostic services, modular repairs, and centralized battery refurbishment, while investing in recycling that can recover up to 96% of materials. The strategy is aimed at lowering running costs and making repairs easier to access, a pragmatic route for a premium marque that prioritizes durability and predictable ownership.

The company also confirms bidirectional charging via V2H and V2G starting in 2026, but rules out V2L due to design constraints. Mercedes isn’t backing rapid battery swapping, instead banking on rising charging-power levels across the infrastructure. Its EVs are built for long service lives, yet the brand stops short of firm predictions over a 30–40-year horizon. Given how quickly charging tech is advancing, the focus on more powerful networks looks more practical than engineering cars around quick-change packs.
