At what level of battery degradation can the Wuling Hongguang Mini get a free replacement?
2 Answers
When the vehicle is still within the three-electric system warranty period, replacing or repairing the battery is free of charge. However, after the warranty period expires or in cases of intentional damage, the battery replacement will require out-of-pocket expenses. Stable charging time is essential: In summer, the charging time should be controlled within 8 hours, while in winter, it should be limited to 10 hours. Excessive charging time can lead to overcharging, which damages the battery. Of course, if the battery indicator light turns off early, an additional half-hour of charging is recommended to ensure the battery is fully charged. Avoid leaving the electric vehicle unused for extended periods: Why does an electric vehicle's battery sometimes degrade faster when not in use? The main reason is battery depletion, which is irreversible. This phenomenon is commonly referred to as "battery starvation."
I've been driving the Hongguang MINI EV for over two years. The key point for free battery replacement due to degradation is when capacity drops below 70% within the warranty period, typically combined with an 8-year or 120,000 km limit. The warranty booklet specifies exact criteria - you need official 4S store testing to confirm. When degradation exceeds 70%, the vehicle's range drops significantly. I find it convenient to monitor battery health via the app. If you notice abnormalities, don't delay - get professional testing immediately to avoid misjudgment. Safety first, as aged batteries are prone to failure. From personal experience, using slow charging protects the battery and extends lifespan. Minimizing frequent daily charge-discharge cycles can delay degradation, ensuring driving reliability without spending on replacements.
