Does Daily Charging Harm Tesla's Battery?

[LeRyan]

Tesla's battery is not harmed as long as it is charged correctly every day. Proper charging has no negative impact: According to battery data from a Tesla owner who drove a Model S P85 for 5 years, covering a total of 76,000 kilometers, the car could travel 426 kilometers on a full charge when new. After 5 years, it could still travel 403 kilometers on a full charge, with only a 5.4% battery degradation. Of course, this level of performance requires meticulous care, attention to detail, and excellent driving habits, which are hard for most people to achieve. The owner mentioned maintaining a good habit of charging the vehicle when the battery level dropped to 5%-10%, and only charging it up to 90%-95%, which helps prolong battery life and minimizes degradation. Battery Replacement: According to domestic regulations, electric vehicles must provide an 8-year or 150,000-kilometer warranty for the battery, during which the battery degradation should not exceed 30%. If the battery degrades significantly, it must be replaced. Tesla offers a product quality guarantee for the power battery and drive unit, ensuring free replacement if severe battery degradation occurs during the warranty period.
