How Long Can a New Energy Battery Last?
2 Answers
Generally speaking, an ordinary car battery may last about 3 to 5 years, while a higher-quality one can last 5 to 6 years, but this also means it will be more expensive. Battery Lifespan: Battery lifespan is measured by charge-discharge cycles, not simply by time! Currently, high-performance lithium batteries can achieve over 4,000 charge-discharge cycles! This means that with one cycle per day, it can last for more than ten years. Expensive Battery Replacement: The reason why new energy vehicle batteries are so expensive is mainly because manufacturers have invested huge amounts of money and costs in battery research and development. This is why batteries are so costly. However, if new energy vehicle battery technology fails to make another breakthrough, hesitant consumers will definitely not choose it.
How long can a new energy battery last? Based on my personal experience, I believe it can last at least 8 to 10 years, depending on how it's used. Extreme temperatures, either too high or too low, can reduce its lifespan. For example, my friend's car in the south has been used for five years, and the battery health is down to 85% because he frequently fast-charged it under the scorching sun. With proper maintenance—like avoiding deep discharges and full charges, and prioritizing slow charging—the battery can last over a decade. Driving habits also matter: frequent hard acceleration can age the battery faster. Manufacturers usually offer an 8-year or 160,000 km warranty, but in real-world tests, many cars perform well beyond that. In short, with good habits, the battery is more durable than you might think.
