EV Battery Lease vs Battery Included Calculator
Some EVs offer a choice between buying the car with the battery or buying at a lower price with a monthly battery lease. Enter both prices and the lease cost to see which works out cheaper.
Frequently asked questions
Which EVs offer a battery lease option?
Battery leasing was pioneered by Renault for the ZOE, and was also offered on the Nissan Leaf and some Smart EQ models. The option has become less common as battery prices have fallen, but it still appears on some models, particularly in the used market.
Is it cheaper to lease or buy the battery?
It depends on how long you keep the car. Battery leasing gives a lower upfront price, but the monthly cost adds up over time. For ownership periods beyond 4-6 years, buying the battery is usually cheaper. Shorter ownership periods may favour leasing.
What happens if I sell an EV with a leased battery?
The battery lease transfers to the new owner. This can make the car harder to sell because the buyer must agree to take over the lease commitment. Cars with the battery included are generally easier and faster to sell on the used market.
Does a battery lease include warranty or replacement?
Yes, this is the main advantage of battery leasing. The manufacturer covers battery degradation and replacement for the duration of the lease. If the battery capacity drops below a threshold (typically 75%), it is replaced at no extra cost.
Are battery leases still worth considering in 2026?
For new cars, battery leasing is increasingly rare as battery costs have fallen. However, if you are buying a used EV with a leased battery, it can still be attractive because the lease provides ongoing battery warranty protection for an older vehicle.
