The Volkswagen ID.4 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 Volkswagen ID.4 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.

• 2020 model year81 to 90%6 years, 55,923 miles, NMC chemistry
• 2023 model year88 to 95%3 years, 27,962 miles, NMC chemistry
• 2026 model year98 to 100%under a year, NMC or LFP depending on the version

For model years where two chemistries appear, the range covers both: LFP holds up better over time than nickel, and the gap widens with age. The battery checker will ask for your version to give an estimate that covers yours alone.

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 Volkswagen ID.4 uses between £6.73 and £10.32 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 £20.30 of fuel per 100 miles, at the average price of unleaded petrol (£1.728 per litre on 2 November 2026).

Bottom of the range: the WLTP official consumption, from 3.2 to 3.9 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.

Sources: 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). Checked on 21 September 2026.

Charging at home: a night on a plug

Plugged in for 8 hours on a 3-pin plug, a Volkswagen ID.4 adds between 45 and 70 miles; on a 16 A commando socket, between 75 and 115 miles, depending on the version and how it is driven.
