As electric vehicles (EVs) continue to surge in popularity in Ontario, California, and the greater Inland Empire, one question remains at the forefront of every car shopper’s mind: “How long do electric car batteries last?” 

Electric vehicle technology has made considerable strides over the years, offering enhanced performance, reliability, and, most importantly, improved battery life. Let’s dig deeper into the lifespan of electric car batteries and what you need to know as you embark on your EV car shopping journey. 

The Basics of Electric Car Battery Lifespan 

Electric car batteries are not a one-size-fits-all feature; their longevity depends on various factors such as the type of battery, driving conditions, and how the vehicle is used. On average, you can expect an electric car battery to last between 8 and 15 years. However, some batteries are expected to last up to 20 years. 

Types of Electric Car Batteries 

  • Lithium-Ion Batteries: These are the most commonly used batteries in modern electric vehicles. They are known for their high energy density and longevity. This technology can be found in many EV’s you can find throughout OAC, including the all-new Toyota, bZ4X, a 4-door SUV & Subaru Solterra as well as the new 2023 Nissan LEAF. 
  • Nickel-Metal Hydride Batteries: Although less common, these are used in some older or entry-level models. They tend to have a shorter lifespan compared to lithium-ion batteries. 
  • Solid-State Batteries: These are an emerging technology expected to offer even better performance and lifespan, although they are not yet widely available. 

According to studies from Consumer Reports, lithium-ion batteries have been shown to degrade only about 2% per year, indicating a pretty robust lifespan.  

Factors Affecting Battery Lifespan 

Several elements contribute to the lifespan of an electric vehicle battery. Understanding these can help you make an informed choice during your car shopping experience in Ontario or elsewhere in the Inland Empire. 

  • Charging Habits: Consistently charging your battery to 100% and draining it completely can reduce its lifespan. It’s recommended to keep the charge between 20% and 80% for optimal longevity. 
  • Driving Conditions: Extreme temperatures, either hot or cold, can affect battery performance. The moderate climate of California tends to be beneficial for EV batteries. 
  • High-Speed Driving: Frequently driving at high speeds can also reduce battery life over time. 
  • Manufacturer Warranty: Always check the warranty when buying an electric vehicle. Many manufacturers offer 8-year warranties or longer, which can give you peace of mind.

  • Regular Inspection: Regular check-ups can identify any issues before they become major problems. Schedule your next service appointment with Ontario Auto Center. 
  • Moderate Charging: As mentioned before, it is best to keep your battery’s charge between 20% and 80%. 
  • Park in a Sheltered Environment: Especially in the Ontario heat, try to park in shaded or covered areas to protect the battery from extreme temperatures. 

The Future of Electric Car Batteries 

The electric vehicle industry is rapidly advancing, and we can expect even better battery technologies in the coming years. Research into solid-state batteries and other innovative technologies could make the question “How long do electric car batteries last?” almost obsolete.
