New Updates: How Long Do Electric Car Batteries Last?
We get a lot of questions from our community about electric car batteries. That is partly because the cost of battery replacement is so high (more on that later), but it is also due to limited information.

Study says that Tesla Model 3 drivers reporting to Recurrent were getting about 72% of EPA range with new cars, 64% after three years. 72->64 is about 12% loss, which is apparently considered fairly typical for NCA batteries.
But it also indicates that the average Tesla Model 3 driver drives much less economically than the EPA driver / test, to the point of 28% worse efficiency (or 39% greater consumption), when looking at the actual range experienced versus the EPA range.
