MS Lithium Rechargeable Battery
3V Type
MS414GE / MS412FE / MS518SE / 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.

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 : −20°C to +60°C
Consult us for using the battery at a temperature beyond
the above temperature range.
• RoHS Compliant
• Approved by UL (Underwriters Laboratories Inc.)
UL File No. MH15628
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. (smartphone, tablet,
cellphone, PHS, cordless phone, fax machine, PC, video
camera, digital camera, tuner, handy terminal, etc.)
• Main power supply for small and slim portable equipment.

*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 specification 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.
Please see Page 19 for resister value. Contact us for further details.
If a constant current charge is required, contact us for more information.
MS Lithium Rechargeable Batteries are not reflowable. Please mount them on PCB by hand soldering.
