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 / MS621T is  -40ºC to +85ºC

▶︎  Approved by UL (Underwriters Laboratories Inc.)
UL File No. MH15628

Battery is not applied to RoHS Directives.  Our battery products do not contain any substances restricted by RoHS Directive.

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.
