Buying a used EV? Follow these tips to avoid costly mistake

Because of depreciation, buyers can often afford newer EVs with more features for the same price as comparable gasoline cars, according to Car and Driver. Most electric-vehicle batteries are built to last and come with comprehensive warranties.

Australia’s Royal Automobile Club of Victoria Head of Policy James Williams encouraged motorists, especially first-time EV buyers, to understand the distinct driving experience and responsibilities that come with electric ownership.

"Motorists transitioning to EVs may not be aware of the safety risks of the increased power and acceleration of quieter vehicles, how to safely apply one-pedal driving, and how to maintain electric vehicle battery performance and lifespan," he said.

Below are key factors to consider before purchasing a used EV.

Assess the battery health

A major concern for used-EV buyers is the battery’s condition, as capacity can degrade over time depending on charging habits and frequency. Unlike fuel systems, battery wear is not immediately visible or noticeable when driving.

"The sweet spot for a used EV is one that’s still under its battery warranty but that’s depreciated enough for significant savings compared to a new one," Alex Knizek, associate director of auto test development at CR’s Auto Test Center, told Consumer Reports.

To estimate the battery’s health, fully charge the vehicle and compare its projected range with the model’s original EPA rating. A figure within 10–20% of that rating generally indicates a healthy battery, according to Car and Driver. Buyers should also consult online data for model-specific degradation and consider a professional battery inspection.

Consumer Reports’ 2023 reliability survey found that 17 percent of 2013 Tesla Model S owners reported replacing their battery packs, each costing around $15,000. "The reality is that if you end up having to replace the battery in an EV, the cost could be more than the car’s worth," Knizek added.

If the car’s battery has been replaced, especially with documentation confirming the work, it is a strong advantage, U.S.’s automotive research company Kelley Blue Book noted. Always verify receipts and ensure the records correspond to the vehicle being sold.

Test the charging system

Ensure that the standard charging cable is included with the car, as it allows for emergency or home charging via a standard household outlet. Check all cables, connectors, and ports for damage or wear, particularly around the charging flap.

Charging speed is another indicator of system health. Manufacturers typically list official charging rates, often expressed as the 10–80% time on a Level 2 or DC fast charger. If the vehicle charges significantly slower than advertised, it could indicate a problem. This is especially important for those who rely on public charging stations, Joseph Yoon, a consumer insights analyst at U.S.-based car research site Edmunds told the Wired.

Poor maintenance or use of low-quality public chargers can also pose safety risks. In 2024, a Tesla driver in Hope, British Columbia, was blasted into the air after an explosion caused by a third-party charging station, according to the Daily Mail.

Check the warranty coverage

Most new EVs come with separate warranties for the vehicle and for the high-voltage battery. These warranties are usually transferable between owners, making them valuable when purchasing secondhand.

"Batteries are often warranted separately from the rest of the car," Sean Tucker, lead editor at Kelley Blue Book, told Wired. He advised potential buyers to confirm whether the battery warranty transfers to a new owner by contacting the manufacturer and providing the vehicle identification number.

A warranty guaranteeing that the battery will retain at least 70% of its original capacity over a set period can offer critical peace of mind, according to the RACV.

Conduct a full test drive

Electric vehicles tend to feature advanced technology. Buyers should test all major systems, including Android Auto, Apple CarPlay, and USB ports.

Some EVs also include "vehicle-to-load" capability, allowing owners to power tools, appliances, or even household devices directly from the car. Testing this feature, even by charging a phone, can confirm functionality.

Inspect the tires

Because EV batteries are heavy, electric vehicles typically wear out tires faster than gasoline cars. Check the tire tread and ask whether the tires have been recently replaced. Many tire manufacturers now offer EV-specific models designed to handle the increased weight and torque.

Evaluate mileage and range

While mileage plays a crucial role in assessing traditional vehicles, it matters less for EVs, which have fewer moving parts and less mechanical wear. "You don’t have to be put off by a high-mileage used EV," Liz Najman, the director of market insights at Recurrent told Wired. Instead, focus on the battery’s age and condition.

Consider how much range suits your needs. For most daily commutes, a 200-mile EV is sufficient, while longer-range models tend to cost significantly more. Drivers who can charge overnight at home may not need as much capacity, and renting a vehicle for occasional long trips could be more economical.
