The Alpine A390 battery: what it is worth, year by year
Alpine A390, since 2025, pack of about 89 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 A390 still under warranty?Battery versions of the Alpine A390
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 Alpine A390 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 Alpine A390 uses between £7.92 and £11.01 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 3.0 to 3.3 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.

The Alpine A390 battery
Sold since 2025, with a pack of about 89 kWh.
The Alpine A390 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.
