Nearly all modern electric cars now come with batteries that will comfortably outlast the useful lifetime of the car itself. The batteries will suffer some degradation over time – in other words, your range when you first get the car will be less than after a few years of driving.The only serious problem that electric cars can run into is if the battery needs replacing, but this is now very rare. For complete peace of mind, the opportunity to avoid the cost of a replacement battery is a significant benefit of leasing a brand-new electric car (compared with buying).Given that all our contracts include the manufacturer’s full warranty, even if the worst did happen and the battery needed replacing, you would be covered under warranty and the battery replaced free of charge. Electric car battery warranties are typically for 8 years.
