MS Lithium Rechargeable Battery

SPECIFICATIONS

OUTLINE

MS (Manganese Silicon) lithium rechargeable batteries, developed by Seiko Instruments Inc., use silicon oxide as the anode and a lithium manganese composite oxide as the cathode. As a result, they offer long cycle life and highly stable overdischarge characteristics.

FEATURES

  • Large discharge capacity :
    For high operational voltage range of 3.3V to 2.0V.
  • Long cycle life :
    Cycle life of over 100 cycles  (over 50 cycles for MS414GE)  under charge/discharge
    conditions of 3.1V to 2.0V (D.O.D.100%).
  • Excellent overdischarge characteristics :
    Continued stable capacity characteristics even after the
    battery is overdischarged down to 0.0V.
  • Operation over a wide temperature range:
    Operating temperature range : −20ºC to +60ºC
    Consult us for using the battery at a temperature beyond
    the above temperature range.

Operating temperature range of the new product MS920T is  -30ºC to +85ºC

  • RoHS Compliant
  • Approved by UL (Underwriters Laboratories Inc.)
    UL File No. MH15628

APPLICATIONS

  • Backup power supply for memory or clock function in various types of electronic equipment for mobile communication, office automation, audio-visual equipment, mobile information equipment, etc. (cellphone, PHS, cordless phone, pager, memory card, fax machine, PC, video camera, digital camera, tuner, handy terminal, PDA, etc.)
  • Hybrid power supply in combination with solar cells.
  • Main power supply for small and slim portable equipment.
