Supplier's note

  1. Three Technical Breakthroughs:

    • Longevity: 5-year shelf life (Pro Model) outperforms industry standards, reducing replacement frequency.
    • Safety: UN 38.3 certification ensures stable operation in high-temperature environments (e.g., power tools).
    • Compact Design: 2.0mm thickness (Base Model) enables seamless integration into thin devices like smartwatches.

  2. Optimal Version Selection:

    • Base Model (CR2020): Ideal for thin devices (e.g., watches) where space is critical.
    • Pro Model (CR2050): Choose for applications requiring extended runtime (e.g., toys, medical devices) with its 5-year shelf life.
    • With the Pro Model’s 5-year shelf life, you can stockpile inventory without performance loss, benefiting OEM partners in seasonal markets.
