by LILucky on Jan 09, 2024

Battery life is a critical consideration for electric vehicle enthusiasts, and Tesla stands out as a pioneer in pushing the boundaries of technology and innovation. In this article, we explore the impressive milestones achieved by Tesla's batteries and delve into the promising future projections, including the much-anticipated million-mile battery.

Current Battery Longevity:

  • Tesla's Model S and X batteries retain over 80% of their range even after driving 200,000 miles.
  • A study on 286 Tesla Model owners worldwide showed just a 5% capacity loss in the first 50,000 miles.
  • Tesla owners retain 90% of their battery capacity, as indicated by a public database initiated in collaboration with the Dutch-Belgian Tesla forum.

Single Charge Performance:

  • On average, Tesla batteries last 262 miles on a single charge, depending on factors like driving conditions and temperature.
  • The Model S Long Range Plus boasts an impressive range of 405 miles on a single charge, providing a seamless driving experience.


Elon Musk's Projections:

  • Elon Musk projected in 2019 that Tesla would develop batteries capable of powering vehicles for 1 million miles.
  • Research led by lithium-ion expert Jeff Dahn, funded by Tesla, surpassed initial projections and hinted at a 4-million mile car battery.
  • A 2022 paper published in the Journal of The Electrochemical Society detailed the breakthrough in charge cycles, reaching 4,000.

Tesla Battery Warranty:

  • Different Tesla models come with varying battery life lengths and retention guarantees, ranging from 8 years/unlimited miles to 8 years/150,000 miles.

Million Mile Battery and Future Developments:

  • Tesla's ongoing work on a million-mile battery has generated significant excitement.
  • The battery, co-developed with Chinese giant CATL, promises to be low-cost and long-lasting.
  • CATL's 'Qilin' battery, set to release in 2022, claims a range of over 620 miles on a single charge.
  • Next-generation battery upgrades are expected to lower the cost per kilowatt hour to under $100.

As we explore the impressive track record of Tesla's batteries and gaze into the future with Elon Musk's ambitious projections, it becomes clear that the longevity and performance of Tesla batteries are continually evolving. The anticipation for the million-mile battery and advancements in battery technology suggest that the answer to "How long do Tesla batteries last?" will only become more impressive with each new model.
