Nissan Leaf owners will need to spend £4920 to replace their car's battery should it fail outside warranty.
All Leafs have a five-year, 60,000-mile warranty against battery capacity failure.
The battery replacement includes a £1000 rebate for the old battery. The total price the owner will pay is £4920.
Nissan has reported that of the 30,000 Leafs sold across Europe, just three batteries have been replaced.
All Leafs sold in the UK are still within warranty.
