Battery runtime depends on the heat setting. On low, expect 6-10 hours; on medium, 4-6 hours; on high, 2.5-4 hours. Actual runtime varies by brand, battery capacity (typically 2000-3500mAh), and ambient temperature—batteries drain faster in extreme cold. For full-day skiing, carry spare batteries or use low/medium settings strategically, bumping to high only during the coldest periods like long lift rides.
