How Long Does an Electric Car Battery Last

What Is An Electric Car Battery And How Does It Work?

An electric car battery is a classification of rechargeable cells packed together closely to power electric cars. It works by converting electrical energy into mechanical energy to power an electric automobile. Electric cars come in diverse shapes and sizes, but almost all work in more or less the same way.

If we go deep into detail, electric car batteries work by using an electric current. Current then moves ions between two electrodes, the cathode, and the anode. The process creates a chemical reaction that releases electrons, powering the electric car. The more these ions move, the more energy is released, so electric car batteries are typically larger.

How Long Do Electric Car Batteries Last, On Average?

Electric car batteries can last for numerous years with minimal degradation. Most electric vehicle makers offer assurances of 8 years or more, though this could vary for every model and make.

Even after the warranty expires, most cells retain around 80% of their original capacity, meaning that they will still be able to power your car for many miles.

You can extend the lifespan of your EV battery further by taking proper care of it, such as avoiding extreme discharge and charging regularly. Your electric car can go on for years without any issue with due upkeep and maintenance.

More on the battery life in the latter part of the article. Read on.

The lifespan will depend on several factors, including intervals of use, charging time, and ambient temperature.

Generally speaking, electric car batteries can last for anywhere from 100,000 to 200,000 miles. However, some drivers have reported that these have lasted even longer. With proper care and maintenance, it is not uncommon for an electric car battery to even last for the life of the vehicle.

Factors That Affect The Lifespan Of An Electric Car Battery

All batteries have a limited lifespan. How long that lifespan depends on various factors, from the type of cell structure to the user style. Electric cars are no exception; they require special care to maximize their lifespan.

Here are some of the most critical factors that affect an electric car battery’s lifespan. By understanding these factors, you can take steps to ensure it lasts as long as possible:

  • How Often Does The Battery Run?
  • Charging Cycle
  • The Ambient Temperature
  • Driving Habits Of The Driver
  • Type Of Charger Used
  • Quality

How Often Does The Battery Run?

Electric car batteries are built to last for many years, but several factors can affect their lifespan. One of the most significant aspects is how often it is put to use or run.

If it is excessively discharged and recharged, it will eventually degrade. If the use is occasional, it will not have a chance to reach maximum capacity and will slowly degrade over time. On the other hand, if it is adequately run, it will gradually lose its capacity as it cycles through charges.

Charging Cycle

Charger capacity and quality also can alter the lifespan. When you plug your electric car into the charger, the process initiates electrons storage. However, if the charger is not powerful enough, or if the charger is left plugged in for too long, the electrons can become “trapped.”

Trapped electrons can reduce the capacity of electric batteries and sometimes could also lead to damage permanently. As a result, it is critical you use only a high-quality charger to charge your EV and avoid overcharging situations.

In addition, driving your car at regular intervals would also help the battery to stay healthy. Use the electrons stored by driving regularly. By following these simple guidelines, you can help to prolong the lifespan of your electric car charging and storage.

If electric cars are left plugged into a charger for extended periods, batteries can overheat and become damaged. Additionally, if is only partially charged, it can develop a “memory” (Except for Li-ion batteries which most of the EVs have) that reduces the amount of charge it can hold in the future.

You do not want your car to play nasty games with you. It is essential only to charge an electric car when it’s nearly depleted and avoid leaving it plugged in for longer than necessary.

The Ambient Temperature

Batteries work best when they function in a constant or less fluctuating ambient temperature. Exposure to extreme heat or cold could be stressful to put more exertion into creating electric energy. Try to keep the temperature between 20 and 30 degrees Celsius to maximize their lifespan.

When batteries are exposed to extreme temperatures, the chemical reactions that allow them to store and release energy disrupts. They may lose capacity over time or become damaged and ineffective.

In particular scenarios, high temperatures can accelerate the degradation of cells while low temperatures could reduce the charging efficiency of the battery. Therefore, it is essential to keep electric car within a safe temperature range to extend lifespan.

Driving Habits Of The Driver

The driving style of a particular person is responsible for many attributes for ages. Color of the car, specification, mileage, upkeep, interiors, music, etc., everything is different for a person based on his/her preferences. Similarly, the expected lifespan of the electric battery would also depend on how the driver drives a car.

Some of you might be in habit to frequently drive through stop-and-go traffic. Such driving style could result in faster degradation.

In addition, those who regularly charge their batteries to 100% capacity will also see a shorter lifespan than those who only charge to 80%. Because deep discharge cycles are challenging on batteries and can lead to reduced capacity and increased stress.

As a result, it is crucial to balance maximizing range and diminishing stress on the motor and charging cycle. If you do make such efforts driving your EV, you can expect your electric car batteries to last for many years.

Some drivers frequently speed up and put brakes abruptly, putting additional strain on the car and causing it to degrade quickly.

In contrast, if a driver carefully conserves energy by planning their route and avoiding unnecessary acceleration, they can significantly prolong the life of their battery.

Type Of Charger Used

Every carmaker has a distinct design and architecture for its numerous models. Therefore, it is nearly impossible to have the same cell pack structure. Same way, the battery chargers also have different charge capacity and design.

The type of charger that you use can have a big impact on the lifespan of your battery. To understand, think of it as charging your phone with a powerful fast charger. Ever notice heating phones while on charging. Fast charging often loads the electric car with a lot of strain causing possible degradation.

On the other hand, slow chargers would take longer to charge the battery of the car but would put less stress on it overall. This helps prevent damage from overheating, and it can prolong its life by as much as 50%.

In addition, the quality of the charger also matters. Chargers made with higher-quality components tend to be more durable and last longer than cheaper chargers. When it comes to electric car batteries, using the right charger is essential for maximizing lifespan.


The quality of the battery is the most important factor. A high-quality make will last longer than a lower-quality one and will be able to withstand more charging cycles.

Lead-acid ones are the most common type of battery used in cars, but they have a shorter lifespan than other types. On the other hand, lithium-ion cell packs can last for up to 10 years with proper care.

  1. I noticed misleading wording, eg. switching back and forth between the 12V and the high voltage drive train battery without context. Reverse argument: Charging to 100 percent has nothing to do with deep discharge. Drive train batteries can not be checked visually. There are many parts in this article requiring proof reading.
