The technology of batteries used to power electric vehicles has advanced significantly, from lead-acid batteries used in GM’s EV1 in the 1990s to lithium-ion batteries used in the majority of electric vehicle models today. Tesla is one of the companies that is at the forefront of the electric vehicle revolution, and batteries are the new gold rush.
Tesla introduced the Model X, a car we’ve previously reviewed, in its quest to dominate the electric vehicle industry and compete with gas-powered SUVs. It’s a high-end electric SUV based on the Model S platform, which is why they’re frequently compared. Even Jeremy Clarkson, who was famously sued by Tesla for reputational harm, thinks the Model X is a fantastic vehicle.
You’ve probably experienced range anxiety if you’ve driven a Tesla Model X. Even if you don’t have range anxiety, you’re probably wondering how long the battery pack will last before it needs to be replaced.
The latest Model X can drive over 330 miles on a single charge
The battery range of a Tesla Model X is determined by the year it was introduced. For example, the 2016 Tesla Model X 90D has a maximum range of up to 257 miles, while the less expensive 60D model has a range of 200 miles (via Car and Driver). According to the EPA estimates listed on Tesla’s website, the latest Tesla Model X has an estimated range of 348 miles, while the Plaid model has an estimated range of 333 miles.
The battery range of a Tesla Model X, on the other hand, can vary depending on the environment and driving variables. To put it another way, cold weather, uphill driving, high-speed driving, tire pressure, and extra cargo can all reduce your Tesla Model X’s battery range. The energy app on your Tesla calculates how long the battery will last after a single charge based on your environment and driving pattern to provide an accurate estimate.
The original battery pack could last over 300k miles
According to Elon Musk, the current battery modules in Tesla vehicles should last 300,000 to 500,000 miles, or approximately 1500 cycles. Aside from that, we know that EV batteries degrade over time, resulting in reduced maximum range. The question is, how does a Tesla Model X battery perform after a lot of miles?
Tesloop, an EV rental company, provided us with an answer after disclosing data from a Tesla Model X that had traveled approximately 330,000 miles (via Autoweek) – it only lost 23 percent of its battery range. Jalopnik and Electrek also investigated some of the highest mileage Tesla Model X vehicles, and according to maintenance records, the battery packs in each vehicle were replaced under warranty after 317k and 325k miles, respectively. However, both sources claim that the batteries were replaced due to a problem with the charging system and software rather than degradation.
It’s worth noting that the data we used to calculate how long a Tesla Model X battery could last comes from older high mileage models, specifically from 2016. Only time will tell if the latest Model X vehicles have battery packs that don’t need to be replaced after 500k miles.

Nonetheless, according to Tesla’s most recent impact report (PDF), your Model X should retain at least 90% of its battery capacity after 200k miles. Furthermore, the Model X battery is covered by the manufacturer’s warranty if it degrades by more than 30% within 8 years or 150,000 miles.
