The Hyundai Inster battery: what it is worth, year by year
Hyundai Inster, since 2024, pack of about 49 kWh. Versions and capacities, manufacturer warranty, expected state of health, possible battery lease and the cost of a failure.
Indicative estimate, excluding diagnosis.
Is this Inster 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 Hyundai Inster
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 Hyundai Inster 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.
- 2024 model year91 to 97%2 years, 18,641 miles, NMC chemistry
- 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 Hyundai Inster uses between £6.06 and £7.89 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 4.2 to 4.3 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.
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). Checked on 21 September 2026.
Charging at home: a night on a plug
Plugged in for 8 hours on a 3-pin plug, a Hyundai Inster adds between 60 and 80 miles; on a 16 A commando socket, between 100 and 130 miles, depending on the version and how it is driven.

Specifications and price ranges given as an order of magnitude, still being confirmed with garages. Only a price given after diagnosis is binding.
The Hyundai Inster battery
Sold since 2024, with a pack of about 49 kWh.
The Hyundai Inster 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.
