The durability of the Polestar 3’s battery is supported by a comprehensive warranty that covers any material defects over eight years or 160,000 kilometers. This warranty ensures that if the battery’s capacity falls below 70% of its original level within this timeframe, Polestar will replace it free of charge, which provides significant peace of mind for owners.
In terms of real-world performance, Polestar has reported lower than expected battery degradation rates in their vehicles, particularly when charged using AC at home, which suggests that the batteries are performing well under typical usage conditions. However, factors such as frequent fast charging and geographical variations in charging infrastructure can influence battery health, so it’s important for owners to be mindful of these factors to maximize the lifespan of their vehicle’s battery.
Overall, while the long-term durability of the Polestar 3’s battery is promising, ongoing maintenance and responsible charging practices will help ensure it remains in good condition over time.
