MS Lithium Rechargeable Battery 3V Type MS412FE/MS518SE/MS614E/MS614SE/MS621FE/MS920SE FEATURES 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. Negative cap Gasket Negative electrode Separater Positive electrode <Cross Section> • 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 • 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. (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.

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 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. Contact us for further details. If a constant current charge is required, contact us for more information. 6 Micro Battery 2007-2008 MS Lithium Rechargeable Battery 3V Type DISCHARGE CHARACTERISTICS (CHARGE VOLTAGE DEPENDENCE) MS412FE MS518SE 3.5 3.5 Charge : max 0.025mA/72 hours (CC/CV) Discharge : 10μA/c.o.v. = 2.0V (CC) Charge: max. 0.06mA/72 hours (CC/CV) Discharge: 10 μA/c.o.v. = 2.0V (CC) 3.0 Voltage [V] Voltage [V] 3.0 2.5 2.0 2.8V 1.5 0.0 0.2 0.4 3.3V 3.1V 3.0V 2.9V 0.6 0.8 1.0 Capacity [mAh] 2.5 2.0 1.2 1.4 1.5 0.0 1.6 MS614E 3.0 3.5 3.0 2.5 Voltage [V] Voltage [V] 1.5 2.0 2.5 Capacity [mAh] Charge: max. 0.1mA/96 hours (CC/CV) Discharge: 15μA/c.o.v. = 2.0V (CC) 3.0 3.3V 2.0 2.8V 1.0 2.0 Capacity [mAh] 3.3V 2.5 3.1V 2.0 3.2V 2.9V 3.0V 3.1V 2.8V 2.9V 3.0V 1.5 0.0 3.0 MS621FE 1.0 2.0 Capacity [mAh] 3.0 4.0 MS920SE 3.5 3.5 Charge: max. 0.1mA/96 hours (CC/CV) Discharge: 15μA/c.o.v. = 2.0V (CC) Charge: max. 0.2mA/96 hours (CC/CV) Discharge: 50μA/c.o.v. = 2.0V (CC) 3.0 3.0 3.1V 3.3V 2.5 Voltage [V] Voltage [V] 1.0 3.5 Charge: max. 0.3mA/72 hours (CC/CV) Discharge: 15μA/c.o.v. = 2.0V (CC) 3.1-3.3V 2.5 2.9V 2.0 1.5 0.0 0.5 MS614SE 3.5 1.5 0.0 2.9V 3.0V 3.1V 3.3V 2.8V 2.0 2.8V 2.8V 3.0V 2.0 4.0 Capacity [mAh] 1.5 0.0 6.0 2.0 2.9V 4.0 6.0 8.0 Capacity [mAh] 3.0V 10.0 12.0 * c.o.v. : Cut Off Voltage (final voltage) CHARACTERISTICS (MS614SE) Charge/discharge characteristics Discharge Characteristics at Various Discharge Current 3.5 3.5 Charge: max. 0.1mA/3.1V, 96 hours (CC/CV) Discharge: 15μA/c.o.v. = 1.5V (CC) 3.0 Voltage [V] Voltage [V] 3.0 2.5 2.0 10μA 5μA 2.5 2.0 1.5 300μA Charge: max. 0.1mA/3.1V, 96 hours (CC/CV) Discharge: 15μA/c.o.v. = 1.5V (CC) 1.0 0.0 1.0 Micro Battery 2007-2008 2.0 Capacity [mAh] 3.0 4.0 1.5 0.0 1.0 100μA 50μA 15μA 2.0 Capacity [mAh] 3.0 4.0 7 MS Lithium Rechargeable Battery 3V Type CHARACTERISTICS (MS614SE) Discharge Temperature Characteristics Overdischarge Characteristics 3.5 3.5 Voltage [V] 3.0 2.5 Battery voltage (V) Overdischarge: 18kΩ discharge/respective period [Capacity measurement conditions] Charge: max. 0.1mA/3.1V, 96 hours (CC/CV) Discharge: 15μA/c.o.v. = 2.0V (CC) 30 days 180 days 90 days Initial 2.0 1.5 0.0 1.0 2.0 Capacity [mAh] 3.0 Voltage (V) Voltage (V) 3.0 2.5 20 days 150 days Initial 200 days 60 days 100 days 80 days 1.0 2.0 Capacity (mAh) 3.0 0°C 25°C 40°C 1.0 2.0 3.0 Discharge capacity (mAh) 4.0 3.5 Storage condition: respective period at 60°C [Capacity measurement conditions] Charge: max. 0.1mA/3.1V, 96 hours (CC/CV) Discharge: 15μA/c.o.v. = 2.0V (CC) 1.0 0.0 60°C –20°C Floating Characteristics (60°C, applied voltage 3.1V) 3.5 1.5 2.0 1.0 0.0 4.0 2.0 2.5 1.5 High Temperature (60°C) Storage Characteristics 3.0 3.0 Charge: max. 0.1mA/3.1V, 96 hours, RT (CC/CV) Discharge: 15μA/c.o.v. = 2.0V, respective temperature (CC) Storage conditions: Each period at 60°C, applied voltage 3.1V [Capacity measurement conditions] Charge: max. 0.1mA/3.1V, 96 hours (CC/CV) Discharge: 15μA/c.o.v. = 2.0V (CC) 2.5 20 days Initial 2.0 150 days 200 days 100 days 40 days 60 days 80 days 1.5 1.0 0.0 4.0 1.0 2.0 Capacity (mAh) 3.0 4.0 DIMENSIONS OF STANDARD TERMINALS OF MS LITHIUM RECHARGEABLE BATTERIES Recommend MS412FE FL26E Recommend MS518SE FL35E MS412FE IL21E 0.5±0.1 1±0.3 1±0.3 0.5 ±0.1 0.5±0.1 0.5 ±0.1 2 ±0.3 2 ±0.3 0.5 ±0.1 1±0.3 0.5 ±0.1 1±0.3 (9.2) 1.6 ±0.5 (Sn plated portion) 1.6max. 0.1±0.02 2.2 ±0.5 φ 4.8max. 2.1max. 2.2 ±0.3 0.1±0.02 1.75 ±0.1 φ 5.8max. φ 4.8max. 2.2±0.5 1.6max. 1.75 ±0.1 0.1±0.02 2.2 ±0.5 1.6±0.5 (Sn plated portion) 1.6 ±0.5 (Sn plated portion) - Contact Seiko Instruments Inc. for batteries with terminals other than the above shapes. - Units: mm - The hatched parts are tin plated (Sn: 100%). 8 Micro Battery 2007-2008 MS Lithium Rechargeable Battery 3V Type DIMENSIONS OF STANDARD TERMINALS OF MS LITHIUM RECHARGEABLE BATTERIES 2 ±0.3 2.5 ±0.3 1.8±0.5 (Sn plated portion) 1.8 ±0.5 (Sn plated portion) 1.8 ±0.5 (Sn plated portion) φ 6.8max. φ 6.8 max. φ 6.8max. 1.5 ±0.5 (Sn plated portion) 2.7max. 2.2 ±0.1 0.15 ±0.02 2.5 +0.3 -0.5 1.8max. 1.8max. 1.6 ±0.2 0.1±0.02 0.5 ±0.1 0.5 ±0.1 2 ±0.3 2 ±0.3 0.5 ±0.1 1±0.3 0.5±0.1 2.5 +0.3 -0.5 0.1±0.02 2.1±0.1 Recommend MS621FE FL11E 0.5 ±0.1 1±0.3 Recommend MS614E, 614SE FL29E 0.5 ±0.1 1±0.3 Recommend MS614E, 614SE FL28E 1.7 ±0.5 (Sn plated portion) Recommend MS920SE FL27E ( 3.3) 2.7max. 2.2 ±0.1 0.15±0.02 0.5±0.1 0.5±0.1 1.25 ±0.3 2.5 ±0.3 0 12.8 -1.0 φ 9.5max. 1.8 ±0.5 (Sn plated portion) 1.7±0.5 (Sn plated portion) MS621FE IL36E 1.8 ±0.5 (Sn plated portion) Micro Battery 2007-2008 1.8 ±0.5 (Sn plated portion) 0.5 ±0.1 1±0.3 1±0.3 0.5 ±0.1 0.15±0.02 2.5±0.4 2.2±0.1 2.5±0.4 φ 9.5 max. 2.2±0.1 2.7 max. 0.15 ±0.02 2.5 ±0.4 φ 6.8 max. φ 6.8max. 2.5 +0.3 -0.5 1.8max. 2.5 ±0.4 2.1±0.1 0.1±0.02 MS920SE IL37E 2.7max. 0 2.5 -0.6 0.5±0.1 1±0.3 1±0.3 0.5 ±0.1 0.5 ±0.1 1±0.3 1±0.3 0.5±0.1 MS614E, 614SE IL38E 1.7±0.5 (Sn plated portion) 1.8 ±0.5 (Sn plated portion) 1.7±0.5 (Sn plated portion) 9
