MS Lithium Rechargeable Batteries

MS lithium rechargeable batteries, developed by Seiko Instruments, 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
    • High operational voltage range of 3.3 V to 2.0 V
  • Long cycle life
    • Cycle life of over 100 cycles (over 50 cycles for MS414GE) under charge/discharge conditions of 3.1 V to 2.0 V [depth of discharge (D.O.D.) 100%]
  • Excellent overdischarge characteristics
    • Continued stable capacity characteristics even after the battery is over discharged down to 0.0 V
  • Operation over a wide temperature range
    • Operating temperature range: -20ºC to +60ºC
  • Operating temperature range for MS920T / MS621T is -40ºC to +85ºC
    • RoHS compliant
    • Approved by UL (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 (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
