Without proper care batteries can wither and die like a delicate tulip roasting in the bright sun from an unseasonably warm spring day – a fact made exponentially worse when the battery in your $60k vehicle no longer functions properly. With that in mind, Tesla just unveiled an impressive new warranty for the Model S battery pack. With the notable exception of a vehicle accident or a curious owner opening the battery pack, under this new plan, Tesla will replace the battery pack for any reason including user error and improper maintenance.
