Reliability is your Security
Utilizi ng t he latest advance design Oxygen
Recombination Technology, Y uasa have applied
their 80 years experience in the lead acid battery
field to produce the optimum design of Sealed
Lead Acid batteries.
FEATURES
Superb recovery from deep discharge.
Electrolyte suspension system.
Gas Recombination.
Multipurpose: Float or Cyclic use.
Usable in any orientat ion.
Superior energy density.
Lead calcium grids for extended life.
Manufactured World wide.
Application specific designs.
Technical Features
Sealed Construction
Yuasa’s unique construction and sealing technique
ensures no electrolyte leakage from case or terminals.
Electrolyte Suspension System
All NP batteries utilize Yuasa’s unique electrolyte susp ension
system incorporating a microfine glass ma t to ret ai n th e
maximum amount of electrolyte in the cells. The electrolyte is
retained in the separator material and there is no fr ee
electrolyte to escape from the cells. No gels or other
contaminants are added.
Control of Gas Generation
The design of Yuasa’s NP batteries incorporates the very latest
oxygen recombination technology to effectively control the
generation of gas during normal use.
Low Maintenance Operation
Due to the perfectly sealed construction and the
recombination of gasses within the cell, the battery is almost
maintenance free.

Terminals
NP batteries are manufactured using a range of terminals which
vary in size and type. Please refer to details as shown.
Operation in any Orientation
The combination of sealed construction and Yuasa’s unique
electrolyte suspension system allows oper ation in any
orientation, with no loss of performance or fear of electrolyte
leakage.
Valve Regulated Design
The batteries are equipped with a simple, safe, low pressure
venting system which releases excess gas and automatically
reseals should there be a build up of gas within t he bat tery due
to se ve re ov e rc ha r ge . N o te . O n n o account should the battery be
charged in a sealed container.

Lead Calcium Grids
The heavy duty lead calcium alloy grids provide an extra margin
of performance and life in both cyclic and float applications and
give unparalleled recovery from deep discharge.
Long Cycle Service Life
Depending upon the average depth of discharge, over a
thousand discharge/charge cycles can be expected.
Float Service Life
The expected service life is five years in float standby
applications.
Separators
The use of the special separator material provides a very efficient
insulation between plates preve nting inter-p late short circuits
and prohibiting the shedding of active materials.
Long shelf Life
The extremely low self discharge rate allows the battery to be
stored for extended periods up to one year at normal ambient
temperatures with no permanent loss of capacity.
Operating Temperature Range
The batteries can be used over a broad temperature range
permitting considerable flexibility in system design and
location.
Charge – 15°C to 50°C
Discharge – 20°C to 60°C
Storage – 20°C to 50°C (fully charged battery)
