Is this Classe B Electric Drive still under warranty?What is this car’s battery worth?
Remaining warranty, expected state of health, battery lease and cost of a failure. All at once — and nothing you enter leaves your browser.
We check, we don’t certify. The date of first registration is shown in box B of the V5C logbook. The state of health given is a range calculated from the battery’s age, mileage and chemistry: only a measurement on the vehicle gives a figure.
Battery versions of the Mercedes-Benz Classe B Electric Drive
A model sold over several years does not have the same battery from start to finish, and two versions are often sold side by side. Identify yours: capacity and chemistry change the range, the expected degradation and the cost of a replacement.

The expected state of health of a Mercedes-Benz Classe B Electric Drive battery
Three model years of this car, at the average French annual mileage of 9,321 miles, each with its chemistry. These ranges describe where a comparable battery usually sits, not yours: use, climate and charging habits spread the fleet widely.
- 2014 model year66 to 79%12 years, 111,847 miles, chemistry not recorded
- 2016 model year71 to 83%10 years, 93,206 miles, chemistry not recorded
- 2017 model year73 to 85%9 years, 83,885 miles, chemistry not recorded
For a figure rather than a range, you need a measurement on the car. What state of health means and how it is measured.
What the energy costs per 100 miles
The WLTP official consumption of this model has not been recorded, or only under the old NEDC cycle, which is not comparable: no figure rather than a guess.
Charging at a public charge point: prices vary too much from one operator to another to be given here.
Compare the cost of every modelSources: consumption from the manufacturer or the European registration database; electricity: Ofgem Energy Price Cap, 1 October to 31 December 2026, direct debit, Great Britain average, no VAT (announced 26 August 2026); real-world gap: TNO 2025 and ICCT 2025; petrol: JRC 2025 and weekly road fuel prices from the Department for Energy Security and Net Zero (DESNZ).

Specifications and price ranges given as an order of magnitude, still being confirmed with garages. Only a price given after diagnosis is binding.

The Mercedes-Benz Classe B Electric Drive pack does not lend itself to module-by-module repair. A diagnosis is still worthwhile: the fault often lies in an ancillary component rather than the pack itself.
