Battery replacements are not provided at no cost by Tesla.
Tesla offers an unlimited mileage, eight-year warranty on the original battery.
If you have to replace your battery due of a defect in the manufacturing process, you may be able to get the cost of the replacement reimbursed by the warranty.
In addition, Tesla offers a warranty on its performance batteries that lasts for four years or 50,000 miles.
However, this is only relevant in the case of defects that negatively impact battery life.
The cost to replace the battery after the warranty expires will depend on the age and condition of the vehicle.
Tesla charges a fee for the battery replacement service, which includes the cost of labour, disposal, and other related fees; this amount may be greater for vehicles that haven't been serviced regularly.
