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.
*1. Nominal capacity: Typical value of discharge capacity between 3.1V and 2.0V
*2. Internal impedance is measured using an AC (Alternating Current) method at the fully charged state.
*3. Maximum discharge current indicates the value of a current for approximately 50% of the nominal capacity.
*4. Cycle Life indicates the times charge/discharge is repeated for approximately 50% of the capacity values in the specifi cation sheet.
*5. 100% and 20% are based on nominal capacity.
*6. A constant voltage charge is recommended, but due to a limit in charge current, it is necessary to insert a resistor to regulate the
