MS Lithium Rechargeable Battery 3V Type
MS412FE/MS518SE/MS614E/MS614SE/MS621FE/MS920SE
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. • Backup power supply for memory or clock function
in various types of electronic equipment for mobile
communication, offi ce 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.

FEATURES
• Large discharge capacity :
For high operational voltage range of 3.3V to 2.0V.
• Long cycle life :
Cycle life of over 100 cycles under charge/discharge
conditions of 3.3V 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 : −20°C to +60°C
Consult us for using the battery at a temperature beyond
the above temperature range.
• RoHS Compliant
APPLICATIONS
SPECIFICATIONS
*1. Nominal capacity: Typical value of discharge capacity between 3.1V and 2.0V
(Note that the discharge capacity of MS614E is between 3.3V 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
charge current.
Contact us for further details.
If a constant current charge is required, contact us for more information.
