MS (Manganese Silicon) lithium rechargeable batteries, developed by Sil, 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.
I) FEATURES
2 o o - Large discharge capacity :
: = e ‘ For high operational voltage range of 3.3V to 2.0V.
& oe _ - Long cycle life :
: sd 2 Cycle life of over 100 cycles (over 50 cycles for
2 MS414GE) under charge/discharge conditions of 3.1V to
P @ * 2.0V (D.O.D.100%).
2 ~ at - Excellent overdischarge characteristics :
& Continued stable capacity characteristics even after the
é
© 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.
em Negative * RoHS Compliant
ane cap * Approved by UL (Underwriters Laboratories Inc.)
E- electrodeNegative UL File No. MH15628

*4. Nominal capacity: Typical value of discharge capacity between 3.1V and 2.0V
**----- End of picture text -----**
*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. *A_ 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 7 for resister value. Contact us for further details. lf a constant current charge is required, contact us for more information. ## AXCAUTION MS Lithium Rechargeable Batteries are not reflowable. Please mount them on PCB by hand soldering. 8 Seiko Instruments Inc. ## | CHARACTERISTICS **==> picture [240 x 10] intentionally omitted <==** **----- Start of picture text -----**
