Data Sheet
NPC SERIES - NPC17-12
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.
FEATURES
1. Double cycle life
NPC operates 500 charge/discharge cycles or twice as
many cycles as conventional cycle use batteries at
75%D.O.D. (depth of discharge).

2. Valve-regulated and maintenance-free
Battery electrolyte retained solidly in the separator and the
innovative gas recombinant system allows minimum gas
emittance freeing the user from maintenance.
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.
Layout
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.

CAUTION
- Avoid short circuit.
- Do not charge in a sealed container.
- Service life and operational characteristics will be
affected by temperature.
- AC Ripple reduces service life.
