Nissan Leaf Mk1 battery capacity loss — bar loss
The 12-bar battery capacity indicator loses bars, indicating permanent capacity degradation in the 24 kWh lithium-ion battery. The Nissan Leaf Mk1 uses an air-cooled battery with no thermal management, making it highly susceptible to capacity loss in hot climates or with frequent rapid charging. Capacity loss of 20-30% within 5 years is common in warm climates. Battery reconditioning services and refurbished replacement packs are widely available.
