Estimated realistic range of the Mercedes-Benz EQA 250 over ten years at typical UK mileage, against the usual 70% capacity warranty floor.
What degradation looks like on a Mercedes-Benz EQA 250
From a realistic 225 miles when new, a typical Mercedes-Benz EQA 250 still manages about 203 miles at 5 years (90% health), 191 miles at 8 years (85%) and 183 miles at 10 years (81%).
The first year usually shows the biggest single drop as the pack settles, after which the fade slows to a crawl. Batteries almost never fail outright; they just gradually carry a little less.
Most manufacturers warrant the battery for 8 years or 100,000 miles against falling below about 70% capacity. On this car, 70% health still means around 160 miles of realistic range.
Habits that keep the battery healthy
- Charge to 80% for daily use and save 100% for long trips
- Avoid leaving the car parked for weeks at 100% or near empty
- Use AC charging for routine and rapid charging for journeys
- Do not fear normal use: the management system protects the pack far better than folklore suggests
