The Tesla Model S is one of the most popular and iconic electric vehicles on the market, known for its sleek design, impressive performance, and cutting-edge technology. One of the most critical components of the Model S is its battery, which is responsible for powering the vehicle’s electric motor and providing a range of up to 373 miles on a single charge, depending on the trim level and driving conditions. As with any battery-powered vehicle, the longevity of the Tesla Model S battery is a major concern for potential buyers and existing owners alike. In this article, we’ll delve into the details of how long the Tesla Model S battery lasts, exploring its design, capacity, and degradation over time.

The Design and Capacity of the Tesla Model S Battery
The Tesla Model S battery is a lithium-ion battery pack, consisting of 7,104 individual cells arranged in 16 modules. Each module contains 444 cells, and the entire pack weighs around 1,500 pounds. The battery’s capacity is measured in kilowatt-hours (kWh), with the Model S Long Range trim featuring a 100 kWh battery and the Model S Performance trim featuring a 95 kWh battery.
The battery’s design is optimized for maximum energy density, with Tesla using a unique cooling system to maintain a consistent temperature and prevent overheating. This allows the battery to maintain its performance and capacity over time, even in extreme temperatures.
How Long Does the Tesla Model S Battery Last?
The Tesla Model S battery is designed to last for many years, with Tesla guaranteeing the battery to retain at least 70% of its original capacity after 100,000 miles or 8 years, whichever comes first. However, real-world data suggests that the battery may retain more capacity than this, with some owners reporting ranges of up to 300 miles or more even after 100,000 miles.
According to Tesla’s own data, the Model S battery loses around 2.5% of its capacity per year, with the majority of this degradation occurring in the first few years of ownership. This means that after 5 years, the battery may retain around 90% of its original capacity, and after 10 years, it may retain around 80%.
Factors Affecting Battery Degradation
While the Tesla Model S battery is designed to last for many years, there are several factors that can affect its degradation over time. These include:
-
Temperature: Extreme temperatures can cause the battery to degrade faster, with high temperatures causing the battery to lose capacity more quickly. (See Also: What Type of Battery Does My Tesla Have? Know Your Options)

Charging habits: Frequent fast charging can cause the battery to degrade faster, as the high-voltage charging can cause stress on the battery cells.
-
Driving habits: Aggressive driving, such as rapid acceleration and braking, can cause the battery to degrade faster.
-
Maintenance: Failure to maintain the vehicle’s software and firmware can cause the battery to degrade faster.
How to Extend the Life of the Tesla Model S Battery
Fortunately, there are several steps you can take to extend the life of your Tesla Model S battery:
-
Keep the vehicle in a cool, shaded area: Extreme temperatures can cause the battery to degrade faster, so keeping the vehicle in a cool, shaded area can help slow down this process.
-
Use the correct charging method: Using the correct charging method, such as Tesla’s Supercharger network, can help reduce stress on the battery cells. (See Also: How Long Do Car Key Battery Last? Typically Lasting)
