        Valve Regulated Lead-Acid Batteries

        Reliability is your security 
        Yuasa NP, NPC and NPH batteries utilise the latest advance design Oxygen Recombination Technology. Yuasa have applied their 80 years experience in the lead acid battery field to produce the optimum design of Sealed Valve Regulated Lead Acid batteries. Yuasa NP batteries are the most reliable batteries in the world, which is why industry choose Yuasa over any other battery for securityfireemergency lighting anduninterruptible power source (UPS) applications.

        Superb recovery from deep discharge.
        Electrolyte suspension system.

        Technical Features
        Sealed Construction
        Yuasa’s unique construction and sealing technique ensures no electrolyte leakage from case or terminals

        Yuasa NP valve regulated lead acid batteries having excellent deep discharge recovery characteristics coupled with long life on float standby, are ideal for numerous applications in both cyclic and standby modes. They are the ideal security battery for alarm systems; the ideal battery for fire systemsthe ideal battery for emergency lighting; and the ideal battery for uninterruptible power source.  For further advice on the use of NP batteries in your particular application please contact our Sales Office.

        Electrolyte Suspension System
        All NP batteries utilize Yuasa’s unique electrolyte suspension system incorporating a microfine glass mat to retain the maximum amount of electrolyte in the cells. The electrolyte is retained in the separator material and there is no free 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.

        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 operation in any orientation, with no loss of performance or fear of electrolyte leakage. (Excluding continuous use inverted)

        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 the battery due to severe overcharge. Note. On no 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.

        The use of the special separator material provides a very efficient insulation between plates preventing inter-plate 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.
