As Tesla ramps up, so does the release of information surrounding the experience, the latest of which concerns the Model 3's battery pack.
New Tesla warranty documents show that much like theand , the Model 3 has a four-year bumper-to-bumper new car warranty and an eight-year battery and power train warranty. However, unlike with Tesla's more expensive models, there is a mileage limit of 100,000 miles for standard batteries or 120,000 miles for Long Range Batteries. The big news is that Tesla guarantees buyers that a Model 3's battery will retain a minimum of 70 percent of its capacity over the course of that eight-year warranty.
One of the chief concerns of people looking at becoming first-time electric car buyers is the longevity of a car's lithium-ion battery pack. Even more than the engine in a gasoline-powered vehicle, the battery pack represents much of the cost of the vehicle, so replacing one in five or ten years is a relatively daunting proposition. Luckily, the first few owners of any given Tesla Model 3 won't have to worry about that.
Tesla's guarantee sounds great, but so far, reality has been even better, according to an independent survey conducted by a group of Dutch and Belgian Tesla owners, nearly all of the 286 Model S owners surveyed are on track to hit 150,000 miles before seeing even a 10 percent degradation in capacity. Whether this trend will continue with Tesla's increased production loads and fluctuations in material costs remains to be seen. At least from a battery standpoint, buying a used in a few years time might be a pretty great deal.
