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
Operating temperature range of the new product MS920T / MS621T is -40ºC to +85ºC
Approved by UL (Underwriters Laboratories Inc.) UL File No. MH15628
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.
