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.
