Data Shows Tesla Batteries Will Last Longer Than Expected

Battery degradation is one of the biggest concerns for electric car owners and potential buyers, but data from Tesla battery packs have been very reassuring so far.

Some good news. Now, you can go out and buy that used Tesla you always wanted.

A survey of over 350 Tesla car owners found that their auto’s battery is lasting longer than expected, reports Electrek. Tesla batteries retain over 90 percent of their charging power after 160,000 miles, according to data gathered by a Dutch-Belgium Tesla owners group. While Tesla cars saw their battery capacity drop by 5% after only 50,000 miles, the rate of battery capacity decline slowed dramatically after that first milestone.

Tesla has no battery degradation warranty on its Model S and X luxury EVs, but guarantees that the Model 3 will retain 70 percent battery capacity after 120,000 miles and 100,000 miles. According to the survey data, Tesla will easily be able to meet this mark.

Electrek also reports that the Nissan Leaf, another fully electric car, loses roughly 20% of its capacity over the first five years. This shows that from a battery perspective, Tesla’s price premium is certainly worth it.
