Cylindrical-type Primary Lithium Batteries - High Power


  • Spiral electrode structure ensures high-rate current discharge.
  • Low self-discharge rate and long life.
    Self-discharge rate: less than 0.5% per year at room temperature.
  • Usable over a wide temperature range
    Operational temperature range : -40°C to +85°C (-40°F to +185°F)
    Consult with FDK when using batteries at temperatures exceeding -20°C to +60°C (-4°F to +1 40°F)range.
  • UL recognition (File No. MH13421)


  • Gas, electricity, and water meters
  • Fire and gas alarms
  • In-vehicle applications (ETCs, eCall systems, etc)


  • Please use tabs or connectors when connecting these batteries to applications.

  • ※ Expected life at room temperature : CR17500EP 20 years , other models 10 years.
    Expected life is reference only and is not intended to imply any guarantee or warranty. Actual life depends on condition of use.
  • ※ Consult with FDK when considering connection method and multiple-cell configuration.
  • ※ CR17335EG and CR17450E-N have the outer can made of nickel plated steel.
  • ※1 Nominal capacity is determined at an end voltage of 2.0V when the battery is allowed to discharge at a standard current level at +23°C.
  • ※2 Current value for obtaining 1.0V cell voltage when pulse is applied for 15 seconds at 50% discharge depth (50% of the nominal capacity) at +23°C.
