How long is the lifespan of an electric car battery before it needs replacement?

Electric car batteries generally have a lifespan of around ten years. Precautions for using electric car batteries: After parking, avoid prolonged use of electrical equipment. The service life of a battery is typically about 3 years. For vehicle battery maintenance, try not to play music after turning off the engine. If the vehicle is parked for an extended period, disconnect the negative terminal of the battery to extend its lifespan. Automobile warranty legal provisions: On October 1, 2013, the national "Regulations on the Repair, Replacement, and Return of Household Automobiles" was officially implemented. Article 17 of the regulations states that the warranty period for household automobiles shall not be less than 3 years or 60,000 kilometers, whichever comes first. The three-guarantee validity period for household automobiles shall not be less than 2 years or 50,000 kilometers, whichever comes first.
I drove an electric car for several years before, and I feel that the battery lifespan is generally around 8 to 12 years before needing replacement, mainly depending on how you drive and charge it. For example, my first electric car lasted over seven years, but its range dropped by almost half, and a health check showed only 65% capacity, so I promptly replaced it. The key indicator is when the fully charged range drops below 70% of the original range—that’s when you need to pay attention. Daily charging habits are crucial: minimize fast charging, avoid frequently draining or fully charging the battery, and keep it within the 20%-80% range for optimal health. Temperature also has a big impact—parking in extreme summer heat or freezing winter conditions accelerates aging. I recommend checking the battery condition during annual maintenance to detect issues early and avoid being stranded. Replacement costs aren’t low, but it’s worth it to extend the vehicle’s lifespan.
