The Kia EV5 battery: what it is worth, year by year

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.

The expected state of health of a Kia EV5 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.

• 2025 model year93 to 99%1 year, 9,321 miles, NMC chemistry
• 2026 model year98 to 100%under a year, NMC chemistry

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

Charged at home, a Kia EV5 uses between £7.16 and £9.85 of electricity per 100 miles.

By comparison, a recent petrol car averages 38.7 mpg (7.3 L/100 km) in real-world use: about £20.55 of fuel per 100 miles, at the average price of unleaded petrol (£1.749 per litre on 5 October 2026).

Bottom of the range: the WLTP official consumption, from 3.3 to 3.7 miles/kWh depending on the version. Top: 25% more, the measured gap between official figures and real-world use. Electricity at £0.2632 per kWh, the Ofgem price cap.

Charging at a public charge point: prices vary too much from one operator to another to be given here.
