Can the battery of a Zhidou still be used after 5 years?

It depends on the specific usage conditions of the owner. Generally, the battery of a new energy vehicle can last 7-8 years. It is recommended to visit a maintenance facility to test the battery and check its performance before deciding whether to replace it. The classification of new energy batteries is introduced as follows: Lithium Iron Phosphate (LiFePO4) Battery: Lithium iron phosphate batteries have excellent thermal stability, are safe, cost-effective, and have a long lifespan, but they have low energy density and are sensitive to low temperatures. The internal chemical composition begins to decompose when the battery temperature reaches 500-600°C, and they do not catch fire or explode due to punctures, short circuits, or high temperatures, with a relatively long service life. However, the vehicle's range is generally limited, and when the temperature drops below -5°C, charging efficiency decreases, making them unsuitable for winter charging in northern regions. Ternary Lithium Battery: Ternary lithium-ion batteries have high energy density, long cycle life, and are resistant to low temperatures, but they have insufficient stability at high temperatures. They can achieve the highest energy density, but their high-temperature performance is relatively poor. For pure electric vehicles with range requirements, they are the mainstream choice and are suitable for northern climates, as the battery remains more stable in low temperatures.
I've driven a Zhidou electric car for 5 years and noticed significant battery performance degradation, especially in winter when the range drops noticeably from 100 km to just over 60 km. This is quite normal as battery internal degradation is inevitable after prolonged use. I frequently used fast charging and often depleted the battery before recharging, which accelerated the aging. I recommend you regularly check battery health - conduct actual range tests before long trips, use diagnostic tools at 4S shops to read data. If the capacity shrinks too much, consider replacement. Battery lifespan depends on usage habits and environment - it might still work for city commuting, but don't expect new-car performance. My car is still operational, though I avoid long-distance trips now.
As a family car user, after driving the Zhidou for 5 years, the battery started having occasional minor issues. One rainy night while driving, it almost stalled, which really scared me. Safety comes first—old batteries can suddenly fail, causing lights to go out or the car to stop abruptly. Check the range and charging efficiency; try charging it fully to see how far it can go. If it's below 70%, it's dangerous. Hurry to a repair shop for a thorough inspection—don't skimp on this expense. A new battery might be expensive, but it's worth it for safety. Usually, try to use the air conditioning less to save power and extend its lifespan a bit.
