approved by UL(Underwriters Laboratories Inc.)
UL File MH 15628
MS412F/MS414/MS614/MS614F/MS614S/
MS621/MS621F/MS920/MS920S/ (MS421S)
APPLICATIONS
• Back up power supply for memory or clock in various
electronic equipment e.g. cellular-phones, cordless
phones, PHS, pagers, memory-cards, FAX machines,
personal computers, PDA, Video cameras, digital cam-
eras, tuners, handy terminals etc.
• Combined use with solar cells.
• Main power source for small and slim portable equip-
ment.
SPECIFICATIONS
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. Gasket
