Even with the surge in the demand for electric vehicles (EVs), one question is on the lips of everyone: how long does an average EV battery last?

It’s no surprise that prospective owners consider their lifespan before making a purchasing decision. The power source for an EV is costly to replace. So, getting answers to the lifetime management of the battery is a crucial consideration.

In this guide, you’ll learn about the battery lifespan of an EV, electric car battery charging cycles, and how to maintain your battery for lasting performance.

How long does an average EV battery last?

What batteries do electric vehicles use?

Electric vehicles use packs of lithium-ion that are similar to those used in laptops and mobile phones. Here are a few benefits of using lithium-ion batteries for EVs:

  • They are quick to charge, efficiently store energy, and offer thousands of charging cycles.
  • They hold their charge longer, even when not in use.
  • Unlike the nickel-metal hydride batteries used in conventional cars, lithium-ion batteries offer a greater energy density.

In terms of battery capacity, the more the kilowatt-hour (kWh) of an EV’s battery, the better it is. Also, the larger the battery capacity of an electric car, the more miles you can drive on the road.

Why do EV batteries degrade over time?

According to Forbes, when lithium-ion batteries increase from 0 to full charge (100 percent) in a cycle, they undergo a thorough use-case. This is relatable; when you accelerate, the energy stored in the battery powers up the motor.

Like phone batteries, EV batteries degrade in health with a continuous cycle of charging and discharging. This means there’s a decrease in the amount of charge the battery can hold. At the same time, there’s an increase in the time needed to recharge such a battery.

The good news, however, about EV batteries is that they are designed to last several years with proper maintenance measures.

EV battery life expectancy

Electric vehicles are powered by packs of a lithium-ion batteries, like that in your phone. So, over time with usage, their lifespan and range reduce. However, EV batteries are built to last several years.

Keep in mind that your battery will lose about 2.3% of its starting range every year.

Under normal driving circumstances, electric car batteries can stay 10 years before needing a replacement. For most people, that’s a lot of periods to keep a new car.

If you’re in the market for a used EV, you must consider the lifespan of the battery before purchasing such a vehicle.
