A British electric vehicle (EV) dealer examined 300 used EVs, and the findings confirm that you don't have to be concerned about your car's battery and its longevity.
- A new video from RSEV reveals why you have no reason to be concerned about your electric vehicle's battery.
- Although electric vehicle batteries do deteriorate over time, the process is extremely gradual, so the battery will generally outlast the car's lifespan.
- Even if you do notice some deterioration over 200,000 miles, battery failure is extremely unlikely in a modern electric vehicle.
So I've analyzed the health of over 1000 vehicles, and here's what I found: Batteries in medium- and long-distance electric vehicles hold up really well.
On average, vehicles retained 90% of their battery capacity throughout approximately 90,000 miles of travel. Indeed, this is quite impressive. However, it is also worth noting that battery deprecation is typically most pronounced in the initial couple of years. Consequently, a vehicle with 130,000 miles accumulated mileage retained 85% of its original battery capacity. Furthermore, numerous examples have been observed of vehicles successfully exceeding 200,000 and even 300,000 miles with battery capacity levels of 80% or higher.
There is still more positive news to share.
First, take a look at this chart to get a sense of the degradation curve:
Let's pan out so the chart displays a range starting from 0% rather than 80%.
It is almost a direct line.
Then take into account that most modern cars come equipped with a "buffer zone" that's not immediately noticeable to the owner. As the battery's performance declines with age, the buffer zone is utilized to compensate for the lost capacity. As a result, although the actual battery pack's range may be diminished, the usable range can potentially remain steady for up to 150,000 miles.
Around 50 percent of the 300 cars sampled were earlier versions of the Tesla Model 3, which is understandable. They're a popular choice and renowned for being able to travel hundreds of thousands of miles on their original battery packs.
Good news: These polls seem to represent the worst-case scenario, due to the dataset. RSEV is a second-hand EV dealer in the U.K., its analysis examines cars that are ending a lease. Leasing operates differently in the U.K. and is common for company vehicles, although its terms normally last between three or four years. As a result, these cars, doing 90,000 or 130,000 miles, not only bear high mileage, but do so in an extremely short period. Most vehicles will take ten years to reach that amount, especially in the U.K., where the average driver covers less distance than in the United States.
This product, which was launched in 2018, represents an earlier generation of battery technology and production management. Consequently, it has the lowest performance among the available options.

- Electric Vehicle Batteries Rarely Experience Failure: Research Suggests
- Research Indicates EV Batteries May Last Beyond a Vehicle's Lifespan with Practically No Degradation.
- Average Tesla Model 3 and Model Y Battery Degradation After 200,000 Miles Actually Shows Off
- Here's a paradoxical scenario: you buy a Tesla, an environmentally friendly electric vehicle, but you're concerned about its battery's lifespan.
- This Tesla Model S Only Saw a 36% Decrease in its Range After 430,000 Miles
- This Tesla Model X 90D has surpassed 350,000 miles on its original battery.
The fact that your 200,000-mile Tesla, which has experienced a 15-20% reduction in original range - keep in mind that degradation slows down after the first year - will remain operable almost all the time. In contrast, an internal combustion engine usually runs well up until the moment it suddenly fails. A Model 3 Long Range with 290 miles of range, despite having less range than a new one with 363 miles, is still practical enough to be your only vehicle, and its gradual degradation means it could be driven for many years. Furthermore, the motor itself is not likely to fail completely.
To be honest, I'm somewhat enthusiastic about this topic. As someone who's particularly interested in dependability, my chief concern with the shift to electric vehicles was that they would become essentially short-term, single-use products with predetermined lifespan dates set by their manufacturers. I strongly dislike how fast smartphones become electronic waste, and I'm also disapproving of several automakers attempting to prevent owners from self-repairing their vehicles.
I no longer worry about that at all. Tesla has made its diagnostic software available to consumers. Its batteries usually last for over 300,000 miles. Its motors are no longer prone to major problems. It has consistently delivered on its promise of EV reliability: A less complex vehicle means fewer components to fine-tune, resulting in a more reliable vehicle. This isn't immediate, as EVs represent new technology. Several automakers are still in their "making mistakes and learning from them" phase, rather than in their mature technology stage.
Cross the valley, and there's a lush meadow on the other side. One where not just Toyotas, Hondas, and American trucks endure for 250,000 miles, but where any company with reliable technology can achieve this milestone. Your car's infotainment system will likely continue to have issues and the window regulator might still be a problem if you buy a high-end brand or a luxury vehicle, but concerns about a 150,000-mile powertrain will soon be a thing of the past.
