The average lifespan of batteries used in heated clothing typically ranges from 500 to 1,000 charge/discharge cycles for lithium-ion batteries, which are the most commonly used type. With proper care and maintenance, these batteries can last up to 6 to 7 years before needing replacement.

Factors Influencing Battery Lifespan

• Battery Type:
  • Lithium-ion Batteries: Known for their high energy density and low self-discharge rate, they provide a good balance of performance and longevity.
  • Nickel-Metal Hydride (NiMH) Batteries: Used in some heated clothing, but generally have a shorter lifespan compared to lithium-ion batteries.
• Usage Patterns:
  • Regular use and proper cycling (charging and discharging) help maintain battery health and can extend its lifespan.
• Storage Conditions:
  • Store batteries with a charge level of around 25-50% in a cool, dry place. Avoid extreme temperatures, as high heat can significantly reduce battery capacity over time.
• Maintenance:
  • Follow maintenance guidelines such as fully charging the battery before long-term storage and periodically checking its condition to ensure longevity.

In summary, while the average lifespan of heated clothing batteries is around 500 to 1,000 cycles, with proper care, some batteries can last 6-7 years, offering reliable performance across multiple seasons.
