Battery lifespan is typically 500–1,000 full charge cycles before capacity drops to 70–80% of original. For most riders, this translates to 3–5 years of regular use. Replacement batteries cost $500–$900 depending on capacity and brand. To maximize lifespan, avoid storing at full charge, keep the battery between 20–80% for daily use, and store at moderate temperatures.
