Transcript

NPC Series VALVE REGULATED LEAD-ACID BATTERIES CYCLIC APPLICATION NPC YUASA NPC SERIES The low maintenance and valve regulated constructions combine with heavy-duty plates and unique separator systems to make NPC service twice as long as conventional counterparts. Operating temperature range FEATURES Charge: – 15 ~ 50°C (5 ~ 122°F) 1. Double cycle life Discharge: – 15 ~ 50°C (5 ~ 122°F) NPC operates 500 charge/discharge cycles or twice as Storage: – 20 ~ 50°C (– 4 ~ 122°F) many cycles as conventional cycle use batteries at Recommended charging method 75%D.O.D. (depth of discharge).

Valve-regulated and maintenance-free • Pumps Battery electrolyte retained solidly in the separator and the • Measuring instruments innovative gas recombinant system allows minimum gas • AGV (Automatic guided vehicle) emittance freeing the user from maintenance. • Magnetic lifts 3. Durability for deep discharge use Yuasa’s state-of-the-art plate barrier prevention and the unique separator systems help endure deep discharge use thus considerably prolonging battery’s service life. 4. Minimal self-discharge Cyclic use batteries tend to be left discharged after usage causing plate corrosion leading to shortened life. Self discharge rate of NPC is as small as only 0.1% a day at 20°C and thus extends the storage period allowed.
