What is the actual lifespan of BYD's lithium iron phosphate battery?
2 Answers
BYD's lithium iron phosphate battery has a theoretical lifespan of around eight years. Below is an introduction to the service life, advantages, and disadvantages of BYD's lithium iron phosphate battery: Battery lifespan: BYD's lithium iron phosphate battery can withstand over 2,000 charge-discharge cycles. With daily charging, it can last for more than five years, while under typical household usage with charging every three days, it can last around eight years. Advantages of lithium iron phosphate batteries: Lithium iron phosphate batteries offer strong safety and stability, high-temperature resistance, and environmental friendliness. Even in the event of a short circuit, they do not explode or catch fire. Disadvantages of lithium iron phosphate batteries: They are relatively bulky, which means they occupy more space in household new energy vehicles. Additionally, while excelling in high-temperature resistance, lithium iron phosphate batteries perform poorly in low-temperature discharge performance.
As an ordinary owner who drives a BYD electric vehicle daily, I've been using the Dolphin for over three years, and the battery performance is still excellent, feeling almost like new. The actual lifespan is generally around 8 to 10 years, or about 2,500 to 4,000 charge-discharge cycles, depending on your driving habits and maintenance. I usually don't drive long distances, just commuting to and from work, charging once or twice a week, and the battery capacity hasn't dropped much. A friend who drives a ride-hailing service has been using a BYD E2 for over five years, and the battery still retains more than 80% health. The key is to avoid charging in extreme high or low temperatures, preferably using the original charger, and not waiting until the battery level drops below 20% to charge. Regular simple check-ups at the 4S shop can prevent aging and extend the battery's lifespan, saving the hassle and cost of replacement. Overall, BYD's lithium iron phosphate batteries are quite durable, and driving for seven or eight years shouldn't be a problem—just drive with peace of mind.
