Everything About Model 3 Battery Degradation (Read This Before You Buy)

Everything About Model 3 Battery Degradation

Tesla’s Model 3 battery degradation is something that came as a surprise to many owners. The battery life in a Tesla seemed to be a benefit that persuaded more people to buy an electric automobile, but that was quickly changed for those who own a Model 3.

Model 3 battery degradation can occur simply because the battery is getting older. Some other reasons for this can be because of how the Tesla owner drives, while other reasons for the battery life to be reduced may be due to how the Model 3 was designed.

No matter the reason why Model 3’s battery life has begun to decrease, a prospective owner of this car needs to know about this issue before driving the car off of the lot. Keep reading this article to find out more information on the battery life degradation in Model 3s, why it may be happening, and if there is any way that you can fix it.

Causes of Battery Degradation in the Tesla Model 3

When you first bought your Tesla Model 3, you were probably excited about all of the benefits that came with it. You were only thinking about the envious looks you would get as you drove past a restaurant or how much you are helping the planet by being so energy efficient.

After a few months, however, you may have begun to notice that the battery life does not last as quickly as it used to. These are problems you were not expecting, and they can quickly become frustrating to encounter. Check out these next few points that explain why this may be happening.

  • Elements of the Design: The manufacturers of your Model 3 can play a big role in determining how much life your battery can hold. Even though all cars are supposedly made equal, keep in mind that this may not always hold true for your Model 3. It truly depends on how your car was made.
  • It Might Be Based on How You Handle Your Car: How you take care of your Model 3 is a good indicator as to whether your battery is more likely to experience degradation or not. If you are constantly leaving the lights on, overcharging it, or always supercharging it, you are probably ruining your battery.
  • Time Has Passed: Even if you are doing everything you can to prevent battery degradation, sometimes it is just inevitable with electric cars. Anything that has a battery and is frequently used, such as an electric car, tablet, or computer, will eventually wear down. It is normal but does not make it any less frustrating.
  • You Are Charging Your Car Too Often: Even though it is an electric car, Model 3s do not need to be charged at all times. In fact, constantly allowing your electric vehicle to reach 100% can ruin the battery life, similar to your phone. Keeping a log of when you plan to charge your car next may help ease your mind.
  • You Are Letting Your Car Run Out of Energy: Contrary to the last point, allowing your Model 3 to constantly reach 0% does not do any good either. Try to charge your car before it drops below 20% so that you will not get into the habit of letting it die.

If you are made aware of the potential reasons behind why your battery has started to drain faster than usual, you will have a better understanding of how to prevent further battery loss. It will save you much time, frustration, and possibly money.

How Much Degradation Can I Expect With My Model 3?

After reading about the logistics of why your battery life may be draining at an unbelievable rate, you may be curious as to how much battery life you have actually lost. On average, research shows that it is normal to have around a 6% degradation with your Model 3 battery and with Teslas in general.

Some percentages, however, have been seen at a much higher number. Some reports state that their battery has degraded 10%, while others express that they have lost about 14% of their energy. This may come as a shock to many Tesla owners because they were not expecting this problem out of a seemingly perfect vehicle.

Degradation in Various Climates

One thing to consider about battery degradation in a Model 3 car is whether or not the climate you live in will impact it in a negative way. The weather in a northern state such as Michigan will be much different than the weather in Miami, Florida. And the colder the weather is, the worse your battery life will be.

This is due to using the heater more in the winter. Using the heater forces the energy in the car to focus on producing warmth, which takes away from energy that will power your car to drive. Since heaters are used constantly in environments that are cold, battery degradation will happen much quicker than with Model 3’s in a warm area.

How Can I Prevent Battery Degradation in my Model 3 Car?

If you are wondering how to prevent battery degradation in your Model 3, you are not alone. This is a question that the majority of electric car owners have after realizing that their battery life has decreased a noticeable amount, and it is a question that deserves answers.

These next few sections will be crucial for you to read before you purchase your Model 3 so you will understand what you should be doing from the beginning. If you already own this electric car, then these points will still be helpful and will hopefully prevent further battery loss.

Keep Up with the Daily Forecast

The weather is unpredictable and out of your control, but how you take care of your Model 3 is not. Because this is an electric car, you need to pay more attention to the weather and how your car is responding to it. Here are a few weather conditions that you need to be mindful of when you own this vehicle:

  • An Extremely Sunny Day: This high temperature has the potential to damage different parts of the car, including your battery. It is best if you park your car in a place that does not get very hot.
  • Weather That Is Very Cold: When it gets really chilly outside, the heat is going to be blowing throughout the car as hard as it can. Because of this, the battery can be damaged, and the life of it can be decreased significantly.
  • Rainy Roads: To some people’s surprise, getting an electric vehicle wet is not a major concern. However, driving on rainy roads can force your Model 3 to use extra energy to maintain traction and stability.

Do Not Speed If It Is Not Necessary

Even though most drivers have a tendency to speed, there are not many reasons why they should be doing so. Speeding is okay when it comes to medical emergencies or bathroom emergencies, but not if you are trying to catch your favorite show. Speeding increases the potential for accidents and tickets, along with also ruining your car.

The logistics are simple – the faster you go, the faster your battery will be drained. Prolonged speeding will cause battery degradation, and the best way to stop this from happening is to step on the brake pedal.

Do Not Be Afraid to Use Your Car

As you are reading all of these dos and don’ts with your Model 3, you may be tempted to limit your electric car usage as much as possible. If you are thinking this way, you can feel better knowing that how much you use your car does not necessarily impact your battery and its life.

In fact, it is probably more beneficial to drive your car around instead of leaving it sitting in a garage or parking deck. Like any car, if it is not driven for a certain amount of time, it may not function as well as it should or normally would.

Know Where You Are Driving To

A helpful tip that will help you preserve your battery life is to know where you are driving to. If you do not have the proper directions, using the GPS that is built into your Model 3 or a map on your smartphone would be your best bet.

By knowing where you are going, you are not aimlessly driving around and looking where to go. You are also more likely to continuously press the brake pedal and cause a lot of sudden movements in your vehicle. If this happens over a long period of time, you run the risk of hurting not only your car’s engine but also its battery life.

Know When and When Not to Charge Your Car

One of the key components of having an electric car is knowing when and when not to charge your car’s battery. For your Model 3, this step is especially important since they have a greater tendency to lose their battery life than other electric vehicles. When it comes to charging your Model 3, here are a few points to keep in mind:

  • Charge your battery before it reaches 0% if at all possible. If you are only charging your car when the battery dies on a consistent basis, your battery will be under some stress. It will also be more convenient for you in the long run because you are not worrying about if your car has enough battery life or not.
  • Do not overcharge your battery. If the battery percentage is constantly reaching 100%, there will be just as many problems as there would be if it was always dead. Every once in a while, it is okay to reach the maximum charging percentage, but do not make it a daily habit.
  • Instead of overcharging, unplug your Model 3 when it reaches around 80% battery life. This gives the battery room, instead of being overcharged and having issues.
  • Avoid the fast charging options whenever possible. This feature is a convenient one and something that appears to be a good idea, but it will eventually ruin your battery as time passes. Even though most people do use fast charging, your Model 3 was not made to constantly work that hard in such a short period of time.

Turn Off (Almost) Every Setting You Can

One trick for saving your Model 3’s battery that gets overlooked a lot is turning off any extra settings that you can find. This may be done by turning off settings like sentry mode or even limiting the number of times you log onto the Tesla app on your cell phone.

The entire charging process can become tricky for someone, especially if they are new to owning a Model 3. It can often be overwhelming for a person to learn everything at once, so you must learn how to preserve your battery life before you own an electric car.

Replace the Battery in Your Car

This is probably one of the most expensive ways to reduce battery degradation, but it gets the job done. If you decide that this is what you want to do, you are looking at a job that will cost you anywhere from $3,000 to $7,000, without any added costs or taxes. After you add on extra fees, you are ultimately looking at paying over $15,000.

Replacing the battery will also cost you your time and patience. On a normal day, it will take around 13 hours to replace the battery in your Model 3 car. When you take into account the other cars in front of your car, how fast the mechanics work, and if there will be other unexpected issues, you may be looking at more than a few days.

What Does the New Model 3 Battery Mean for My Car?

Tesla had been made aware of the depleting battery life that made up their Model 3 cars. When this was found, they decided that their 2021 Model 3 cars would come with a new type of battery. This battery, which is 82 kWh compared to the previous battery pack that was around 20 kWh lower, will be more beneficial than some people realize.

Take a look at these next few points that explain what the benefits of this new battery are:

  • This will give Model 3 owners more energy for their cars. In fact, your electric vehicle will be getting about five times more energy than it was with the original battery design. The extra energy gives your Model 3 more miles to drive and allows you to stop worrying about the next time you need to charge.
  • The Model 3 is a little bit more cost-effective than it once was. With the new battery, Tesla is aiming to eventually have their electric cars sell in a similar price range as a regular vehicle. This will allow for many more cars to be sold and for new and improved innovations to appear.
  • The new battery will give the Model 3 a longer life and can typically be driven over one million miles. This will require less time waiting for your Model 3 to charge and less money to be spent trying to fix the battery.
  • For the Tesla company, the production will be much quicker and will promote more money and business. As prices go down, sales are going to go up.

Considering that it is only the year 2021, the future is very bright for Model 3s and the Tesla company. As the years go on, there will undoubtedly be more and more improvements and innovations to electric vehicles. There are limitless possibilities, and it is exciting to think about all that will take place.

Does Tesla Have Warranty That Protects Against Battery Degradation?

Tesla understands that many people have concerns when it comes to their battery getting worse over time. Because of these worries, you will be happy to know that their warranty covers the issue of battery degradation and will protect Tesla owners from eventually having a bogus battery.

The warranty protects Model 3s and other Teslas for up to eight years, or 100,000 miles. The battery also has to hold at least 70% of its energy. With this warranty, you will be able to replace what is necessary, as long as you meet those requirements.


Battery degradation in a Tesla Model 3 can happen due to a variety of reasons. Whether the battery is damaged because of how the owner drives, the weather conditions, charging habits, or it is just how the Model 3 was manufactured, battery degradation is a frustrating situation that anyone with an electric car has to deal with.

Ultimately, it is important to remember that even if you take the best care possible of your Model 3, the battery life of any electric car will be shortened over time. This may be a bit disheartening to hear, but it is important to know this information so that you do not buy a Model 3 and run into problems that you did not anticipate.
