Mercedes battery information
Most modern Mercedes vehicles use two batteries: a main AGM under the bonnet or boot and a smaller auxiliary battery that supports start-stop and electronics. Both can fail independently, and both must be registered to the SAM module after replacement.
Our technicians carry the full Varta Silver Dynamic AGM range and the small AGM auxiliary sizes for C-Class, E-Class, S-Class and the GLC/GLE SUVs. Every replacement includes on-site coding and a printed confirmation.
Battery types we fit for Mercedes
- AGM main battery
- Small AGM auxiliary battery
- Standard SLI on older A-Class and Vito

- Always fit like-for-like technology — replacing an AGM with standard SLI will fail within 18 months.
- Modern Mercedes models require BMS coding after replacement — we do this on-site at no extra charge.
- Recommended brands for Mercedes: Varta, Bosch.
