EV battery replacement: What you need to know
Quick insights
- Modern EV batteries are designed to last over a decade, often outlasting the typical vehicle ownership period.
- Many EV manufacturers include battery warranties that last for several years or a set number of miles, offering coverage for certain potential issues over time.
- Proper care, such as avoiding extreme temperatures and maintaining moderate charge levels, can help extend the lifespan of an EV battery.
Electric vehicle (EVs) are becoming more visible on the road, and interest in them continues to grow among consumers. Despite this attention, there are still misconceptions about the cost and maintenance of EVs. Some people may worry about battery replacement costs, but in reality, such replacements may be rare, and when they are needed, there are often affordable options.
Below is a break down of what you may need to know about EV battery replacement.
How often do EV batteries need to be replaced?
The short answer is generally not often. Modern EV batteries are designed to last many years, often outlasting the typical ownership period of a vehicle. While some models have experienced recalls that required battery replacements, in general, battery replacement is rare. Most EV owners are unlikely to need a replacement during the time they own their vehicle.
EV batteries are built to last longer than the lithium-ion batteries in our phones or laptops.
How much does it cost to replace an EV battery?
Many potential EV car buyers worry about the cost of replacing a battery. While replacing an EV battery can be expensive, such replacements are relatively uncommon. Additionally, automakers and third-party providers offer various options that can help make battery replacement more affordable when it is needed.
Fortunately, EV manufacturers are required to provide a battery warranty for several years or a significant number of miles, to ensure that car buyers are protected in case of battery issues. Most warranties cover the full cost of a replacement if the battery stops working as intended, though some may only cover certain conditions. In some cases, manufacturers will replace a battery if its capacity falls below a specific threshold, even if it still functions. Warranties usually do not cover damage caused by accidents, flooding, fire or vandalism.
Avoid replacement with proper EV battery care
Even though EV batteries are built to last for at least a decade, here are a few ways to help protect and prolong their performance and durability:
- Avoid extreme temperatures. Extreme heat or intense cold can degrade an EV battery. If possible, it’s best to keep your EV in a climate-controlled garage.
- Don’t let the battery drop to zero. EV batteries perform best when they are not fully depleted or constantly charged to full capacity. Regular, moderate charging helps preserve battery health over time, similar to how car engines operate most efficiently when not pushed to extremes. Following a consistent charging routine can help extend the life of your EV battery.
- Plan ahead. If you know you’ll be away from your EV for a while, don’t leave the battery with an empty or full charge, as this can also contribute to its degradation.
- Limit DC fast charging. While this type of charging — which allows you to quickly charge your vehicle away from home — is great for road trips, it’s not ideal for battery life. Try to limit DC fast charging for travel or emergencies.
- Be mindful of your driving habits. Rapid acceleration, especially in cold temperatures, could temporarily reduce battery efficiency, so easing into your drive may help your EV perform more smoothly.
In summary
Although concerns around battery replacement may be one of the top reasons some consumers haven’t purchased an EV, battery replacements are usually infrequent — most EV batteries will last longer than the average person keeps their car. However, if a battery replacement is necessary, manufacturers’ warranties may cover the costs. There are also many ways to care for an EV battery to help prolong its lifespan.
