Tesla
batteries last approximately 200,000 to 500,000 miles, or about 15 to 35 years. Each battery can last for about 272 to 405 miles on a single charge. An average electric vehicle (EV) will need a replacement battery when it has lost 20% of its range—but you might end up replacing the vehicle itself before you reach this point. Most users have reported Tesla battery loss at only 5% after 100,000 miles.
According to Elon Musk: Tesla batteries are built to last for the full lifespan of your car: between 200,000 and 500,000 miles. The average person drives 273 miles a week, so you can expect your Tesla battery to last anywhere from 15 to 35 years, depending on your driving habits.
What that means: Tesla batteries will rarely (if ever) need to be replaced. As long as you practice proper maintenance, you’ll probably need to replace your car before you need to replace the battery.
However, driving an electric car means stopping to recharge your battery on long trips (more than 275 miles). And charging stations still aren’t as common as gas stations, so you’ll need to plan your trip accordingly.
