How Long Does an Electric Vehicle Battery Typically Last?

Electric Vehicle Battery Lifespan: A Closer Look

The lifespan of electric vehicle (EV) batteries has always been a topic of interest among users. Many have asked: how long does an electric vehicle battery normally last, and how can its durability be enhanced? Today, I would like to share my personal insights on this matter.

Types of Batteries in the Market

When examining battery usage, the primary types available are lead-acid batteries and lithium-ion batteries. For two-wheeled electric vehicles, lead-acid batteries are commonly used. Therefore, my discussion today will focus more on lead-acid batteries. A typical lead-acid battery may start to show a significant decrease in range after 2 to 5 years of use. For example, a battery that originally provided a 60 km range might only deliver 10 km or less after several years of use. At this point, it indicates that the battery's lifespan has essentially been exhausted, and it's time to replace it with a new one. Of course, battery performance varies, with some not lasting beyond 2 years, while others may still function after 5 years, but generally, they fall within the 2 to 5-year range.

Tips for Extending Battery Life

1. Maintain a Steady Speed: Riding at a constant speed of around 20 to 25 km/h ensures more stable vehicle operation, lower power consumption, extended range, and easier battery protection, thereby prolonging its lifespan.

   Avoid Fully Depleted Charging: It's not advisable to let the battery drain completely before recharging. Regularly depleting the battery to empty can reduce its lifespan, especially when riding uphill at low battery levels, which can lead to battery strain. For ordinary electric vehicles, try to recharge when the remaining battery level is around 30% to 50%.

3. Use Vehicle-Specific Chargers: Avoid using chargers interchangeably. Charging also significantly impacts the battery. In households with multiple electric vehicles of different brands and models, using a single charger for incompatible batteries can cause damage, pose safety risks, and accelerate battery wear, affecting its lifespan.

Conclusion

In summary, the normal lifespan of most electric vehicle batteries ranges from 2 to 5 years, with some models potentially falling below 2 years or exceeding 5 years. To maximize durability, users should maintain a steady riding speed, charge the battery reasonably, and avoid using incompatible chargers. Please note that these are my personal views and should be taken as a reference.
