How Much Does A Tesla Car Battery Weigh?

Tesla is one of the most premium EV manufacturers in the world. If you ever thought of which car a person like Tony Stark would drive, it would be a Tesla. Well, he did drive an e-Tron in Avengers: Endgame, so you need not imagine it too much.

The technical specs represent a marvel in automotive engineering. The Model S can go from a standstill to sixty in less than 2 seconds. There is barely any noise, and you can let the autopilot take over in mild traffic conditions in case you wish to relax for a long stretch. However, none of that would be possible with an advanced battery pack.

In this article, we’ll look into its various properties, particularly how much a Tesla car battery weigh and how it affects the car’s performance.

What Kind of Batteries Does Tesla Use?

Tesla uses lithium-ion batteries manufactured by Panasonic and LG. There are other general manufacturers from China, but those two are the primary suppliers. All batteries have a similar structure – about 1000 cells merged together to create a high-density pack to power the car. The lithium-ion batteries are further available in three cathode variants, depending on which car you prefer.

  • Nickel-Cobalt-Aluminum (NCA): NCA batteries use aluminum, which is an excellent conductor. They are sourced from Panasonic and focus on increased performance with a high current output.

  • Nickel-Cobalt-Manganese (NCM): NCM batteries have a manganese cathode that enables them to conduct electricity for extended periods without overheating. Thus, they are the batteries that provide long-range in cars like the Model Y. Most of these batteries are made by LG.

  • Lithium-Iron Phosphate (LFP): LFP batteries don’t have a nickel cathode, which cuts down on manufacturing costs. Thus, while the batteries are less capable than their siblings, it is perfect for entry-level cars like the Model 3.

How Long Does a Tesla Battery Last?

Tesla gives you a warranty of 300,000 miles (482,000 Km) on its LFP and NCA batteries and 500,000 miles (804,000 Km) on its NCM batteries. However, if you keep an optimum maintenance schedule, like not missing service and never discharging below 50%, you can get an additional 100,000 miles (161,000 Km) before you need to replace the battery pack.

How Much Does a Tesla Car Battery Weigh?

Since Tesla uses multiple kinds of batteries, it is best to consider their weight individually. The various battery variants by designation are mentioned below.


It is the NCA battery pack that focuses on performance. It weighs about 1,200 lbs (544.3 Kg). You can find them in high-performance trims like the Model X and Model S.


The 2170-type batteries are NCM variants that grant the car a range of 400 miles (643 Km) or more. They weigh around 1,183 lbs (536.5 Kg) and are available as options for the Model 3 and Model X. They are also the default battery pack for the Model Y.


Due to the size of the Model Y, which is essentially an electric SUV, the default battery pack is unable to grant it enough range. So, Tesla offers a bigger battery pack that weighs around 4,416 lbs (2003 Kg). It is the heaviest of the lot and is present on the base of the car to keep it stable.


It is the cheapest and lightest battery type because it contains few metal components. Prismatic batteries weigh around 1,060 lbs (480.8 Kg). You can find them as the default battery pack in entry-level trims like the Model 3.

How Much Does it Cost to Replace a Tesla Battery?

While Tesla car batteries can go for hundreds of thousands of miles without maintenance, replacing them can set you back a lot. Depending on which trim you drive, replacing your Tesla battery can cost you between $13,000 to $20,000, with the 4680-type being the most expensive.

Are Tesla Batteries Reliable?

Yes. Tesla batteries can usually last you several years without requiring too much maintenance. They are sourced from reputed Asian manufacturers like Panasonic and LG. Both of these have an excellent track record when it comes to batteries.

Tesla batteries come encased in a robust steel alloy that can withstand most vibrations and shocks. It keeps the batteries secure within a shell while fortifying the bottom part of the chassis. Additionally, all Tesla batteries are waterproof, resistant to dust, and rarely have a speck of rust, even after years of usage.

Do Tesla Batteries Use Coolant?

Tesla uses a HOAT-based coolant for its batteries that keep them from getting too hot during long drives. Moreover, the car has a decent airflow system to keep the motor and battery pack cool at high speeds, which is when the current drawn is at its peak.

Does Insurance Cover Tesla Battery Replacement?

Tesla offers a warranty on all of the cars that leave the Gigafactory floor. In the case of batteries, it lasts for the first 8 years or 150,000 miles (248,000 Km), whichever comes earlier. If the battery retains 70% of its original capacity during that period, Tesla will replace it for free.

In terms of insurance, Tesla has an accidental insurance cover that lasts for the first 4 years, or 50,000 miles (80.4 Km), and replaces any damaged batteries for free. If you desire third-party insurance, you should check in with your company to understand their terms for EVs. It is essential because many insurers have different conditions for electric and fossil fuel-driven cars.


And that’s all there is to it. We hope you now have a clearer idea of how much does a Tesla car battery weigh. While the individual cells are only a few pounds, they can go above a thousand to create ample energy storage. Do you still have any burning questions?
