To answer the question how long a Tesla battery lasts, we have to look at the battery life.
Over the years, the battery looses part of its capacity.
You might have noticed the same on your mobile phone. A new phone will last all day. But when it’s several years old, the battery is often flat after half a day.
Is this going to be a problem in Tesla’s?
No. On average, cars with 160,000 miles on them still have 90% of their battery capacity remaining (source). Based on real world data available, a Tesla battery should still have 80% battery capacity after 500,000 miles of driving.
Furthermore, Tesla’s warranty covers the repair or replacement necessary to correct defects in the battery:
- Model S/X: 125,000 miles
- Model 3: 100,000 miles, with minimum 70% retention of battery capacity
- Model 3 Long-Range: 120,000 miles, with minimum 70% retention of battery capacity
