Tesla Battery Degradation Less Than 10% After 160,000 Miles

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.
Now the latest data shows less than 10% degradation of the energy capacity after over 160,000 miles on Tesla’s battery packs.
A group of Tesla owners on the Dutch-Belgium Tesla Forum are gathering data from over 350 Tesla vehicles across the world and frequently updating it in a public Google file.
We have previously reported on the data, but they have since added many more vehicles and those vehicles have been driving a lot more – completing more battery cycles.
The data clearly shows that for the first 50,000 miles (100,000 km), most Tesla battery packs will lose about 5% of their capacity, but after the 50,000-mile mark, the capacity levels off and it looks like it could be difficult to make a pack degrade by another 5%.
The trend line currently suggests that the average battery pack could cycle through over 300,000 km (186,000) before coming close to 90% capacity.
