Estimated realistic range of the Renault 5 E-Tech 52kWh over ten years at typical UK mileage, against the usual 70% capacity warranty floor.

What degradation looks like on a Renault 5 E-Tech 52kWh

From a realistic 210 miles when new, a typical Renault 5 E-Tech 52kWh still manages about 190 miles at 5 years (90% health), 178 miles at 8 years (85%) and 171 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 145 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
