Coin-type Primary Lithium Batteries


  • Low self-discharge rate and long life.
    Self-discharge : Approx. 1% per year at room temperature.
  • Usable over wide temperature range.
    Operational temperature range
    : -20°C to +60°C (-4°F to +140°F)
    (CR-1/3N, 2CR-1/3N)
    : -20°C to +70°C (-4°F to +158°)
    (other models)
  • UL recognition (File No. MH13421)


  • Electronic notebooks
  • Electronic automobile keys (keyless entry)
  • LED-related devices
  • Memory backup power source


  • Available with secondary processing (multiple cells, tabs, connectors, etc) in accordance with use.
  • Nickel-plated phosphor bronze or stainless steel should be used for battery contact terminal materials.
    To ensure stable contact conditions, contact pressure of several newtons is recommended when attaching.
