MS412FE FL26E.

_**MS Lithium Rechargeable Battery**_ 

_**3V Type**_ 

## **MS414GE/MS412FE/MS518SE/MS614SE/MS621FE/MS920SE** 

## **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 3.3V to 2.0V (D.O.D.100%). 

- Excellent overdischarge characteristics : 

- Continued stable capacity characteristics even after the battery is overdischarged down to 0.0V. 

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. 

- 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

- *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 charge current. 

   - Contact us for further details. 

If a constant current charge is required, contact us for more information.
