MS Lithium-Ion Rechargeable Battery <3V Type>
FEATURES
• Large discharge capacity:
Large discharge capacity for high operational voltage
range of 2.0V to 3.3V.
• Long cycle-life:
Over 200 times cycle-life under the charge/discharge
condition at 2.0V to 3.3V (D.O.D 100%).
• Excellent over-discharge characteristics:
Continued stable capacity characteristics after the bat-
tery is over-discharged down to 0.0V.
• Approved product by UL
Manganese Silicon Lithium-ion Battery (MS series) is
approved by UL(Underwriters Laboratories Inc.)
UL File MH 15628

Sll own developed MS(Manganese Silicon) Lithium-ion re-
chargeable battery addresses the demand most effectively.
The battery uses silicon oxide as anode and lithium manga-
nese composite oxide as cathode. As a result, it offers twenty
times the capacity of conventionally available batteries, in ad-
dition to longer cycle-life and highly stable over-discharge
characteristics.

As for the minimum limit resistance R,
please use the value which satisfies
the following two formula;
1)In the case a battery voltage is 3.0V:
R> (Vc-3.0-Vf) / I

2)In the case a battery voltage is 0V:
R> (Vc-Vf) / I
