A man who has driven his 2020 Tesla Model 3 100,000 miles decided to do a battery test on it to see how the EV had held up.
Tesla introduced the Model 3 in 2017, and by 2021, it had become the first EV to sell more than 1 million units.
Despite the car’s success, there are some who are still reluctant to make the switch from a gas-powered vehicle to an all-electric one, and one of the main concerns is battery degradation.
Like pretty much everything that is powered by batteries, their efficiency and usefulness degrade over time as the battery itself degrades.

Of course, EVs aren’t immune to this.
Several high-mileage Tesla owners have shared the results of their battery tests, and it hasn’t always been great news.
This 250,000-mile Model S now takes a staggering two hours and 41 minutes to fully charge; meanwhile, this guy – who racked up 1.2 million miles in his Model S – has had to buy three new batteries during that time.
In a group dedicated to high-mileage Teslas on Facebook – appropriately named the Tesla High Mileage Club, 2020 Model 3 owner Adnan Mahmood shared the results of a battery test after driving 100,000 miles.
He explained that he bought the vehicle used with 32,000 miles on the clock and has since hit 102,000.
Adnan went on to say that he had fitted the Tesla Model 3 with a new set of tires shortly after buying it, had replaced the 12V battery once, and had replaced the upper and lower control arms at 100,000 miles.
So, how did the five-year-old Tesla fare? Pretty well, actually.
Despite racking up 100,000 miles, the battery health showed a not-too-shabby 85 percent, which means its energy retention is ‘within the expected range’ given its age and miles.
Fellow Tesla owners were divided on whether this was a good result for Adnan or not.
One person said their 2019 Model S had done similar miles but was still at 94 percent, while others thought the ‘minimal wear’ wasn’t worth worrying about.
