How Long Does a Tesla Battery Last? - Their Rated Lifetime Mileage

Electric vehicles like Tesla replace the traditional combustion engine with electric motors and batteries.

Since electric motors have just a fraction of the moving parts of a combustion engine, the maintenance for electric vehicles is almost non-existent when compared to traditional vehicles.

Electric motors are extremely reliable and last a long time. So when someone is considering a Tesla or another electric vehicle, a common question is how long do the batteries last.

Teslas have large battery packs that give them a longer range than most electric vehicles. A Tesla battery pack can range from 65 kWh up to 100 kWh, giving some Teslas as much as 375 miles of range.

Factors That Affect Battery Life

How long an electric vehicle battery lasts will vary. There are various factors that will affect the lifespan of a battery. These factors fall into one of two categories, those under an owner’s control and those that are outside of our control, such as battery aging.

Lets first discuss those factors that we are in control of. A well maintained and cared for battery will increase its lifespan.

Avoid Low and High-State of Charges

Lithium-ion batteries, which most Teslas use degrade faster when they are left at a very low state, or a very high state of charge for long periods of time. That means that an owner should avoid using the battery all the way down or charging it to 100% on a regular basis.

Most Teslas should also not be charged to 100% for everyday use. Charging a battery to 80 or 90% for day-to-day use will greatly increase the life of the battery. This doesn’t mean that you can’t charge the battery all the way to 100% occasionally. A good example of when you’d want to charge your battery all the way would be when going on a road trip. However, it should not be done on a regular basis.

The exception to this rule is electric cars with lithium iron phosphate batteries (LFP). LFP batteries use a different chemistry and are not affected by very low or high state of charges. Tesla currently uses LFP batteries in their standard range Model 3 and Model Y vehicles.

Temperature and Climate

The temperature of a battery will also affect its battery life. There is a certain temperature range that a battery should stay within to prevent degradation.

The safe temperature range will vary based on whether the battery is being actively used.

This is one area where Tesla sets itself apart from the competition. Some EVs do not have thermal management systems for their batteries, letting the battery get as hot or cold as its environment.

This puts a great deal of stress on the battery and will cause degradation if the battery is left in cold or hot environments for prolonged periods.

Lithium-ion batteries will start to degrade when exposed to temperatures under 32°F or above 80°F.

Without a thermal system the power output of the car is also limited in order to prevent the battery from overheating.

Teslas have the best thermal management in any car. What this means for you is not only will the battery last much longer than in other EVs, but it will also allow the car to charge quicker and have higher performance.

Tesla battery management is fantastic and it is completely automatic. In fact, owners can’t even tell when their car is managing their battery’s temperature. It happens all automatically, while driving, charging or even while their car is sitting in a parking lot.

Reducing Fast Charging

Another factor that plays a role in battery life is extremely fast charging. Charging the battery at lower voltages is generally better for the battery than higher voltages.

Although the negative effects of fast charging are less severe than leaving your battery with a high state of charge, they should be limited if possible. We would recommend not using Tesla Superchargers as your main form of charging your Tesla.

Fast Discharging

In a similar manner in which fast charging routinely can decrease battery life, fast discharging on a daily basis will also have an affect on battery life.

Everyday driving with the occasional spirited drive is unlikely to have any affect on your car’s battery life. However, if a vehicle is raced on a track on a regular basis, it could lead to some negative effects.

Although fast charging or discharging can affect a battery’s lifespan, they are not major contributors.

Battery Aging

There are various other factors that will affect the lifespan of a Tesla battery pack. Factors that we won’t have any control over.

The biggest one of these factors is the age of the battery. The age of the chemicals inside of the battery will play a large role in determining the battery’s usable life.

Although lithium-ion batteries start to age the day they’re created, they can last up to 20 years.

Charge Cycles

Charging and discharging a battery is known as a charge cycle. Charge cycles are a large contributor to the lifespan of a battery. It’s why many batteries are rated by the number of charge cycles they can support.

One charge cycle is equivalent to using an amount of energy that is equal to 100% of the battery capacity.

For example, if you charged a battery to 100% and discharged it down to 50% twice, then that would be equivalent to one charge cycle.

Although Tesla doesn’t specify the exact number of charge cycles for their batteries, it is believed that they will last up to 1,500 charge cycles.

What Happens When a Battery Ages

As a battery ages and degrades, it will start to hold less of a charge. A battery that has degraded, may only hold 90% of its original capacity and that capacity will continue to drop as the battery continues to age.

Eventually, the battery will no longer have a practical use in the vehicle and will need to be replaced after many years.

It’s normal for a new Tesla to lose some capacity in its first year. We’ve seen degradation rates of up to 5%. However the battery degradation will generally stabilize after the first year and the degradation rate will drop.

Conclusion

There are many factors that go into how long a Tesla lithium-ion battery will last. Mindful owners can reduce battery degradation and increase their lifespan properly maintaining their battery.

Owners can let Tesla manage their battery state by leaving the vehicle plugged in and not charging their cars all the way to 100% on a daily basis, unless of course they have a LFP battery.

However, there are other factors that will also have a big part in how long a Tesla battery lasts.

Since there are many factors that go into how long a Tesla battery will last, the exact mileage someone gets out of a Tesla battery will vary.

Since we know that newer Tesla batteries have a lifespan of about 1,500 charge cycles, we can use that to estimate the battery's lifetime mileage.

Taking charge cycles and the car's EPA mileage into account, we estimate that the lower range Model 3's battery will last about 400,000 miles.

While at the higher end, the Model S has a 375 mile range according to the EPA, bringing the battery's lifetime mileage up to 560,000 miles.

In 2019, Elon Musk commented on the Model 3's battery longevity, saying that the Model 3 has a battery that should last 300,000 to 500,000 miles.

Although the car's battery may last only 300,000 miles, other parts of the car are designed to last much longer. The car’s body and drive unit are made to last one million miles. So even after the battery needs to be replaced, the car still has a lot of life left.

The average person in the US drives an average of 14,000 miles per year. If a Tesla battery only lasted 300,000 miles, it would still last approximately 21 years for the average driver.

Although Tesla is at the forefront of electric vehicles and battery development, work continues to find batteries that last longer, are cheaper to produce and have higher capacities.

Battery Warranty

All Teslas come with the typical new car warranty. However, Tesla offers a separate, longer, battery and drive unit warranty.

The exact battery warranty will vary slightly by model, but their terms are fairly similar. The warranties range from an 8 year or 100,000 mile warranty, all the way up to an 8 year or 150,000 mile warranty, whichever comes first.

The warranty is based on the battery holding a minimum of 70% of its capacity over the course of the 8 years.

Future

Battery technology has stayed stagnant for a long period of time. It’s only more recently that electronics and now electric vehicles are pushing for improved battery technology.

We’re likely to see tremendous improvements in battery technology over the coming years as companies figure out how to produce batteries with higher capacities and reduced weight.

Electric cars, boats and even planes will continue to push for improved battery technology.

Million Mile Battery

Tesla is currently developing higher capacity, structured battery packs that will decrease the weight of a vehicle, leading to better efficiency.

One of Tesla’s goals with its new battery technology is to have a battery that will last one million miles.

Real World Battery Lifespan

Tesla released their first Model S in 2012, so there are now various Teslas with high mileage that give us a better idea of how long a Tesla battery will last in the real world.

Tesloop, a company that offers one-way Tesla rentals between major cities has several Teslas with high mileage. One of their vehicles racked up more than 400,000 miles, although the battery did need to be changed at 317,000 miles.

Another owner, Hansjörg Gemmingen has almost 900,000 miles on his 2013 Model S. His car has gone through two battery replacements during this time, but it’s a true testament to the longevity of Tesla’s batteries.

Keep in mind that these vehicles are 8 and 9 years old now and Tesla had only been creating cars for a few years when the vehicles were built.

Tesla has undoubtedly learned and improved their products since these early vehicles. We'd expect newer batteries to last even longer.

Musk Shares What to Expect in FSD v12.4 Next Week; Talks About Abilities of FSD v12.5 and v12.6

Less than two weeks since its last FSD update, Tesla is getting ready to release FSD v12.4, with CEO Elon Musk hinting at significant improvements. The current version, 12.3.6, introduced Autopark and High Fidelity Park Assist for vehicles equipped with ultrasonic sensors in the U.S. and Canada, along with minor fixes for FSD.

Just an hour ago, Musk shed some light on Tesla's next FSD update. Through his X account, Musk teased the imminent release of v12.4, stating, "Probably start rolling out 12.4 next week." Moreover, he provided insights into the development process and the features users can expect in the upcoming 12.4 version, as well as v12.5 and v12.6.

What to Expect in FSD v12.4

Musk says that FSD 12.4 has extensive retraining of AI models that particularly focuses on refining the comfort of passengers by addressing concerns around abrupt acceleration or braking. Musk previously commented on the next versions of FSD saying that FSD v12.4 and 12.5 would be major improvements, and while v12.4 may be a major step forward, it looks like its main focus will be on being more natural and smoother.

"Probably start rolling out 12.4 next week."

FSD v12.5 and v12.6 to Handle More Complex Scenarios

Looking ahead, Tesla is already laying the groundwork for future updates according to Musk. The CEO previously stated that Tesla is constantly working on FSD updates that are three to six months ahead of what’s in production, so they have a good idea of what the software will be able to handle in the future.

Today on X, Musk said that there's ongoing testing for FSD versions 12.5 and 12.6, which involves tackling complex scenarios. Musk says this includes navigating narrow, one-way roads and handling unexpected road closures, requiring the vehicle to reverse and find alternate routes. 

Actually Smart Summon in v12.5?

Tesla’s Autopilot lead, Ashok Elluswamy, previously talked about how FSD would gain the ability to go in reverse when Tesla is ready to release Actually Smart Summon. If the ability to reverse is still tied to some of the abilities of Actually Smart Summon, then, it’s possible we may see Tesla’s better summon implementation in version 12.5 or 12.6.

Vehicles to be Able to Communicate with Fleet

Musk also gives us some insight into vehicle communication, saying vehicles will need to be able to communicate with the fleet so that you "don't get a whole bunch of Teslas stuck down a road."

Instead of vehicle-to-vehicle communication, Tesla will likely have vehicles report back to the "mothership," where Tesla can aggregate data and report it to nearby vehicles. This is similar to how vehicles report traffic today, instead of talking directly to each other.

Spending on AI

Tesla's commitment to advancing its AI capabilities is evident through its substantial investments. Musk recently emphasized the company's dedication to spending around $10 billion throughout 2024 on training and inference AI. Musk said that any company that isn’t spending billions on AI this year just won’t be able to compete.

Expansion of FSD 

Tesla appears ready to start the expansion of FSD, and it looks like China may be up first. Musk's recent visit to Beijing to discuss a potential FSD rollout and data sharing shows that Tesla is ready and serious about FSD's expansion.

While FSD's rollout in China appears promising, Musk remains cautiously optimistic about expanding into other markets. He believes that FSD v12 is ready for supervised FSD in left-hand drive (LHD) countries, while right-hand drive (RHD) markets like the UK and Australia may require additional time.

An In-Depth Look at Tesla's New Music Player in Update 2024.14 [Photos & Video]

One of the exciting new features of Tesla update 2024.14 is the improved media player for the Model 3 and Model Y.

Tesla's media player has gone through some drastic changes over the years, but this appears to be the best revision yet.

The previous media player had four states... yes, four. It made for a confusing experience, even for owners who used the car every day.

The four states included:

• The "default" state included a small player closest to the driver with some of the most used buttons

• The second state was the enlarged view when you dragged up on the media player that revealed additional buttons such as shuffle and search

• There was also its minimized state, which placed the music player’s icon in the dock and led to confusion

• And lastly, if you had a music service open fully on the right part of the screen AND minimized the media player, then the player would hop over to the top of the larger music panel on the right.

It created for an inconsistent experience and all of the players had their downsides. There just wasn’t a solution that worked all of the time. Thankfully the new music player addresses most of these issues.

Tesla used to have a media player that ran along the bottom of the right part of the screen

What’s New

The first thing Tesla did was reduce the number of states essentially down to two. You have a regular media player and a minimized player. You don't have to drag up on the player to access the shuffle or search functions and you can’t “lose” the player by minimizing it to the dock anymore.

One-Tap Access to Shuffle, Repeat and Search

What Tesla did was move all of the crucial media functions from the previous larger player directly to the main player. This now gives you one-tap access to functions like shuffle, repeat, search, playback speed, audio levels, and search.

Not only were these functions hard to access before, but they were hidden underneath the player, making discovery for new owners difficult.

Improved Progress Bar

The progress bar on the previous player was difficult to see since it was just a slim line at the bottom of the player.

The new player has a thicker progress bar that separates the top portion of the player, which houses the album art, song title, and a couple of functions, and the bottom portion, which contains more controls. Tesla also added a circle to the progress bar, making it more obvious you can not only scrub through the media but also lets you easily see your current spot.

Accessing More Functions

More music player options open to the right

Since the larger media player was removed, so was some of the functionality that it included. All the important items were moved to the main media player such as audio settings and search, however, the other functionality such as access to Favorites, Sources, Recent Songs, and Next, was moved to the larger music app.

If you tap on the new music player, it’ll open up the current music app on the right side that includes music controls, as well as access to your favorites, music sources, upcoming songs and more.

This is also the only way to view the elapsed and remaining times for the current selection, which is useful for longer median such as audiobooks or podcasts.

New Minimized Player

Although the music player doesn't minimize to the dock, it does feature a minimalist version that docks to the bottom of the screen.

When you slide down on the audio player, it'll be reduced to a simple "one-line" player. It simply shows a music icon, the name of the title being played, and an arrow showing you the player can be made larger. There is no longer a gray music icon that appears in the dock when the player is in its “minimized” state.

The new music player no longer minimizes to the dock

Modern UI

The player itself also looks more modern, it now features a translucent background, instead of a solid color like before. The new background lets vehicle animations subtly shine through, a lot like the effects used on modern operating systems.

What Models Will Support It

According to Tesla’s social media post on X, the ‘Visual updates’ in update 2024.14 are limited to AMD Ryzen-based Model 3 and Model Y vehicles, meaning only vehicles manufactured after about 2022+. The exact timeline depends on your vehicle and region, but you can check to see which processor your vehicle includes by navigating to Controls > Software > Additional Vehicle Information.

New Player in Action [Video]

DominicBRNKMN shows off the new music player in action below.

Will We See Intel Atom Support?

The new music player isn’t doing anything crazy in this latest iteration. We believe we'll see this updated player come to Intel Atom vehicles eventually. The Cybertruck already includes the new media player, among the other design changes, so when Tesla said only for “Model 3/Y with AMD chip” on X, they likely meant in this specific update.

There's nothing that’s more computationally intensive about this new player except for maybe the translucent background, however, that’s already being done on Intel-based vehicles for some of the navigation modules. There isn’t anything new that the slower Intel processor couldn't handle.

It’s in Tesla’s best interest to keep a common interface between vehicles. Tesla wouldn't want to drastically change the way a common item like the "radio" works between different Model 3 and Model Y years if they didn't have to. That would complicate issues with service and documentation. Tesla wants owners to have the same UI as much as possible, so we there’s a good chance that we’ll see the new media player apply to Intel in the future.

Hopefully, in an upcoming update, Intel owners will receive this streamlined music player. Update 2024.14 is currently rolling out slowly to some vehicles.
