Reliability is your SecurityYuasa NP, NPC and NPH Batteries. Utilising thelatest advance design Oxygen RecombinationTechnology, Yuasa have applied their 80 yearsexperience in the lead acid battery field to producethe 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 orientation (except continuous inverted).• Superior energy density.• Lead calcium grids for extended life.• Manufactured World wide.• Application specific designs.

Technical FeaturesSealed ConstructionYuasa’s unique construction and sealing techniqueensures no electrolyte leakage from case or terminals

Electrolyte Suspension SystemAll NP batteries utilize Yuasa’s unique electrolytesuspension system incorporating a microfine glass mat toretain the maximum amount of electrolyte in the cells. Theelectrolyte is retained in the separator material and thereis no free electrolyte to escape from the cells. No gels orother contaminants are added.

Control of Gas GenerationThe design of Yuasa’s NP batteries incorporates the verylatest oxygen recombination technology to effectivelycontrol the generation of gas during normal use.

Low Maintenance OperationDue to the perfectly sealed construction and therecombination of gasses within the cell, the battery isalmost maintenance free.

TerminalsNP batteries are manufactured using a range of terminalswhich vary in size and type. Please refer to details asshown.

Operation in any OrientationThe combination of sealed construction and Yuasa’sunique electrolyte suspension system allows operation inany orientation, with no loss of performance or fear ofelectrolyte leakage. (Excluding continuous use inverted)

Valve Regulated DesignThe batteries are equipped with a simple, safe lowpressure venting system which releases excess gas andautomatically reseals should there be a build up of gaswithin the battery due to severe overcharge. Note. On noaccount should the battery be charged in a sealedcontainer.

DDaattaa SShheeeettNP SERIES - NNPP44--1122Lead Calcium GridsThe heavy duty lead calcium alloy grids provide an extramargin of performance and life in both cyclic and floatapplications and give unparalleled recovery from deepdischarge.

Long Cycle Service LifeDepending upon the average depth of discharge, over athousand discharge/charge cycles can be expected.

Float Service LifeThe expected service life is five years in float standbyapplications.

SeparatorsThe use of the special separator material provides a veryefficient insulation between plates preventing inter-plateshort circuits and prohibiting the shedding of activematerials.

Long shelf LifeThe extremely low self discharge rate allows the battery tobe stored for extended periods up to one year at normalambient temperatures with no permanent loss of capacity.

Operating Temperature RangeThe batteries can be used over a broad temperature rangepermitting considerable flexibility in system design andlocation.Charge – 15°C to 50°CDischarge – 20°C to 60°CStorage – 20°C to 50°C (fully charged battery)

ApplicationsYuasa NP batteries, having excellent deep discharge recoverycharacteristics coupled with long life on float standby, are ideal fornumerous applications in both cyclic and standby modes. For adviceon the use of NP batteries in your particular application please contactour Sales Office.

Charging For Float Standby ApplicationsCharged at 2.275 volts per cell continuous. The battery will seek its owncurrent level and float fully charged. However, users should be awarethat when charging from fully discharged, the battery can draw an initialcharge current of approximately 2cA. Care should therefore be taken toensure that this initial charge current (if ungoverned) is within theoutput capability of the equipment. Final charge current at 2.275 voltsper cell is typically between 0.0005cA to 0.004cA.

Charging For Cyclic ApplicationsSee cyclic recharge regime graph.

CAUTION- Do not Short Circuit- Do not charge in a sealed container- Service life and operational characteristics will

be affected by temperature- AC Ripple reduces service life.
