how long do electric car batteries last

As electric vehicle (EV) ownership increases and becomes more mainstream, some car shoppers still have their doubts about switching away from vehicles with an internal combustion engine. Although the price of EVs has dropped, the EV tax credits continue, and the range has increased, many consumers are hesitant to own one. Car shoppers have a variety of concerns about taking the plunge, with many centered around relying on batteries and EV infrastructure. A common question is how long do electric car batteries last.

Three main worries are the lack of public EV charging options, a short driving range, and the need to potentially replace the EV battery. Also, people who live in multifamily buildings or lack a dedicated parking spot may have issues charging at home. In addition, lack of knowledge about EVs continues to be a hurdle to widespread adoption. In particular, consumers need more information about EV batteries and, specifically, how long they last.

Electric car battery technology has rapidly advanced in the last decade, and many vehicle shoppers hold onto outdated or inaccurate information on the topic. Therefore, it is critical for EV professionals to educate consumers and help dispel myths.

Electric Car Battery Lifespan

While lead-acid car batteries last about 3 to 5 years, EV battery pack lifespan is much longer. Typically, today’s EV batteries last 10 – 20 years. Many car manufacturers offer an 8 to 10-year or 100,000-mile warranty on electric car batteries, which can help ease consumer concerns about battery longevity.

However, like solar panels, EV batteries don’t typically give out one day and stop operating. By contrast, they slowly degrade over time and become less effective in storing energy, decreasing vehicle range by 1% to 2% annually. This means the vehicle can eventually travel a shorter distance on a single charge.

What Kind Of Battery Packs Do EVs Use?

Plug-in hybrid electric vehicles (PHEVs), hybrid electric vehicles (HEVs), and battery electric vehicles (BEVs) all use lithium-ion EV battery packs. Laptops, tablets, cell phones, e-bikes, and solar PV battery storage use lithium-ion batteries as well.

These battery banks have numerous advantages over other types because lithium-ion batteries have:

● High energy per unit mass

● High power-to-weight ratio

● Good temperature performance

● High energy efficiency

Advances in lithium-ion battery technology have allowed vehicle range to also increase due to greater energy density. Now, numerous EVs on the market have ranges over 300 miles on a full charge, including the BMW i4, Kia EV6, Hyundai Ioniq 5 Long Range AWD, and Tesla Model 3 Long Range. Other models have moderate ranges, such as the Chevy Bolt at 259 miles. Some automakers have models with much smaller ranges, like the Nissan Leaf with a range of up to 149 miles.

Some EVs even have bidirectional charging abilities. This means that energy from the EV battery can power other loads. With this application, an EV can help power a home, business, the power grid, another EV, or specific loads. However, when an EV battery pack supplies power for other uses, it may reduce its driving range.

Factors That Impact How Long Electric Car Batteries Last

Numerous factors impact battery life, but only some are easily within the control of EV drivers. The level of lithium-ion battery degradation greatly impacts its ability to hold a charge. Eventually, drivers will want to replace electric vehicle batteries. Although degradation is inevitable, there are steps drivers can take to slow it down a bit, extending the useful life of the battery.

Maintain Certain EV Battery Charge Levels

Many EV professionals recommend keeping the battery charged between 20% and 80%. It can put strain on the battery pack when it is completely discharged or fully charged, which slowly reduces its capacity over time. Although charging to 100% enables the vehicle to travel farther, it isn’t recommended to maximize how long EV batteries last.

Avoid Storing The EV Battery At 100% Charge

If an EV needs to sit for a long time between uses, it's best for the electric car battery not to be fully charged or discharged. Thus, a state of charge between 20% and 80% is ideal. Smart charging stations can end charging at a certain level, helping drivers achieve the desired level of charge. Also, many electric cars have settings that control the maximum battery charge to help extend electric car battery life.

Avoid Regularly Using DC Fast Charging Stations

There is some concern in the EV industry about the habitual use of DC Fast Chargers (DCFC), also known as Level III chargers. Habitual rapid charging can cause a minor decline in battery capacity compared to Level II chargers. If possible, drivers should use DCFC chargers sparingly.

Monitor Exposure To Extreme Temperatures

EV batteries can have a shorter lifespan in warmer climates. Extremely warm temperatures while driving, charging, and parking can strain EV batteries, shortening their lifespan. Whenever possible, EV drivers should park in the shade on warm days.

FAQs About How Long EV Batteries Last

Many drivers have questions about battery banks, electric car battery life, and battery capacity because they are paramount when considering the cost of ownership and the driver experience.

How does electric car battery life compare to a gas-powered car battery?

The batteries in gas-powered cars usually last only about 3 to 5 years, although it depends somewhat on use patterns. However, these lead-acid car batteries cost dramatically less and are easier to recycle than lithium-ion EV batteries. In contrast, EV lithium-ion batteries can last 10 to 20 years and typically are covered under a manufacturer’s warranty for a certain number of years or miles.

Strict laws in many states result in nearly 100% of lead-acid batteries getting recycled. This is good news for the environment because it helps reduce the need for extracting virgin raw materials.

Do EV batteries come with manufacturer warranties?

Most car manufacturers, including Volkswagen, Ford, Toyota, Renault, and Chevy, offer an 8 to 10-year or 100,000-mile warranty on electric car batteries. They provide a reasonable estimate of how long electric car batteries last. But, warranties vary a bit by the automaker.

For example, Tesla offers an 8-year or 120,000 miles (whichever happens first) warranty on batteries, with a minimum of 70% battery retention over the warranty period. Rivian offers an 8-year or 175,000-mile battery warranty at 70% retention.

How long does a Rivian battery last?

The Rivian R1T first hit the market in mid-2021, so it's a bit early to know the Rivian battery lifespan definitively. However, the battery pack and electric drive train system come with an 8-year/175,000-mile warranty for the Quad Motor and an 8-year/150,000 mile for the Dual Motor. This is really similar to the Tesla battery pack warranty, which also varies by the model. This provides a reasonable estimate for Rivian battery life.

How long does an electric car battery last while driving?

Many electric cars can provide between 150 to 400 miles (240 to 640 km) of range per full charge under ideal driving conditions. If you are driving at 50 mph, you can typically drive for 3 to 8 hours, depending on the capacity of the EV battery. However, the battery charge lasts less time when accelerating quickly, using the heat or air conditioner, driving on hilly roads, or in cold weather.

What can I do to extend how my Rivian battery life?
