Manganese Rechargeable Lithium Batteries

These batteries use Manganese Composite Oxide for the positive material and Lithium Aluminum alloy for the negative material. Manganese Rechargeable Lithium Batteries
Features
  • Stable Operating Voltage of 2.5V.
  • Charging Possible at 2.8V.
  • Low self-discharge rate and long cell life.
    Self-discharge rate : Approx. 2% per year at room temperature.
  • Usable over wide temperature range
    Operational temperrature range : -20°C to +60°C (-4°F to +140°F )
    Consult with FDK when using batteries at temperatures exceeding
    -20°C to +60°C (-4°F to +140°F ) range.
  • UL recognition (File No. MH13421)
Applications
  • Memory backup power source for Note-PC, Cellular phone, DSC and Camcorder.
  • Electronic keys for automobiles (keyless entry)
  • Memory backup power source for fire alarm
Others
  • Available to meet customers package requirements (multiple cell, with tabs, connectors, etc)
  • Use nickel-plated phosphor bronze or stainless steel for terminal materials for battery contacts. To ensure stable contact conditions, several N of contact pressure is recommended when attaching.

* Expected life is 5 years at R.T..
* Consult with FDK when considering multiple-cell construction.
*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 2.0V cell voltage when pulse is applied for 15 seconds at 50% discharge depth(50% of the nominal capacity) at +23°C.
