It's usually a slow process, and the rate of degradation can vary depending on how you use and charge your car. For example, some studies and real-world data have shown that the Model 3 battery typically loses about 1-2% of its capacity per year. So after, say, five years, you might see a loss of 5-10% of your original range. This is just a general estimate, of course. The actual degradation can be different for each car. Tesla designs its batteries to minimize degradation, and the company offers a warranty to cover significant battery capacity loss within a certain timeframe and mileage. This warranty gives you some peace of mind knowing that Tesla stands behind its product. The rate of degradation tends to be highest in the first year or two and then slows down. Many Model 3 owners report that their battery degradation has leveled off over time. Several factors can influence battery degradation. High temperatures can accelerate the process, so living in a hot climate might lead to slightly faster degradation. Fast charging, while convenient, can also put more stress on the battery over the long term. And frequent, deep discharges (running the battery down to almost zero) can also take a toll. However, modern EVs, including the Model 3, are designed to withstand these conditions better than earlier generations of EVs. Overall, the Tesla Model 3 battery durability is pretty good, with most owners reporting that their batteries hold up well over the years. Understanding battery degradation and how to manage it can help you get the most out of your Model 3 and keep it running for a long time.
