Examples of How Long Tesla Batteries Last
According to Tesla’s impact report, the batteries are built to last the life of the vehicle, which the company estimates at roughly 200,000 mile lifespan (though we’ve seen several models go over that mark).
However, we also found that the actual lifespan of a Tesla battery can vary depending on factors such as:
- driving habits,
- charging habits(!) – more here on good charging habits for Teslas.
- weather conditions
- maintenance.
Here are a few examples of how long Tesla batteries have lasted in real-world scenarios:
| Location | Model | Mileage | Battery Health |
|---|---|---|---|
| U.S. | Model S | 559K miles (900K) | 80% capacity remaining |
| Sweden | Model S | 248K miles (400K) | 90% capacity remaining |
| U.S. | Model S | 621K miles (1M km) | <90% capacity remaining |
As you can see, these Tesla drivers were able to get a lot of mileage out of their batteries before experiencing any significant degradation.
Of course, these are just a few examples, and your experience may vary.
It’s worth noting that Tesla offers a warranty on its batteries that covers them for 8 years or 150,000 miles, whichever comes first.
Depending on the model you choose, you may also be able to purchase an extended warranty that covers the battery for even longer.
When Do Teslas Normally Need New Batteries?
As we mentioned earlier, Tesla batteries are designed to last for a very long time. However, there may come a point when you need to replace your battery.

Does Supercharging Affect the Battery’s Lifespan?
According to Tesla, Supercharging does not significantly affect the lifespan of the battery. Tesla’s batteries are designed to handle the high charging rates of Superchargers, and the company has implemented several measures to protect the battery during Supercharging.
One such measure is the active thermal management system that keeps the battery at an optimal temperature during charging.
This helps prevent overheating and minimizes stress on the battery.
Additionally, Tesla’s Superchargers use a tapered charging profile that slows down the charging rate as the battery gets closer to full capacity. This helps prevent overcharging and further protects the battery.
That being said, frequent Supercharging can still have some impact on the battery’s lifespan.
Charging a battery to 100% and leaving it at that level for an extended period of time can accelerate battery degradation. Similarly, charging the battery frequently to high levels can also cause some degradation over time.
Therefore, while Supercharging is generally safe for your Tesla’s battery, it’s best to use it only when necessary, such as on long road trips.
For daily charging, it’s better to use a Level 2 charger or a Tesla Wall Connector, which provide a slower but gentler charging experience that is easier on the battery.
In summary, Supercharging is a convenient and fast way to charge your Tesla on long road trips, and it’s generally safe for your battery.
However, frequent Supercharging and charging to 100% can accelerate battery degradation, so it’s best to use Supercharging only when necessary and to use gentler charging methods for daily charging.
What Causes Tesla Car Batteries to Degrade Faster?
While Tesla car batteries are known for their longevity, there are some factors that can cause them to degrade faster than expected.
Here are some of the reasons why:
- High temperatures: Exposing a Tesla car battery to high temperatures can cause it to degrade faster. This is because high temperatures can cause the electrolyte in the battery to break down, which can lead to a decrease in capacity over time.
- Frequent fast charging: Fast charging is convenient, but it can also cause the battery to degrade faster. This is because fast charging generates more heat, which can cause the battery to degrade over time.
- Overcharging: Overcharging a Tesla car battery can cause it to degrade faster. This is because overcharging can cause the battery to overheat, which can damage the cells and cause them to degrade over time.
- Deep discharging: Discharging a Tesla car battery to a very low level can cause it to degrade faster. This is because deep discharging can cause the battery to lose capacity over time.
While these factors can cause Tesla car batteries to degrade faster, it’s important to note that proper care and maintenance can help extend the life of the battery.
This includes avoiding extreme temperatures, charging the battery at a moderate rate, and avoiding deep discharging whenever possible.
