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 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 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. 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 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. Separators 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. Operating Temperature Range The batteries can be used over a broad temperature range permitting considerable flexibility in system design and location.

NPH/NPW High performance batteries specially designed for applications requiring high rate discharge, supplying up to 50% (NPH), (NPW) more power (Watts) for short durations when compared to conventional NP models. NPC Specifically designed to suit the arduous requirements of cyclic applications allowing increased cycle life (at least double that of conventional types). (NPC Shortform refers) NPL Long Life Model also to BS6290pt4 (FR Options) Dedicated literature available on request. (NPL Shortform refers). Applications Yuasa NP 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. For advice on the use of NP batteries in your particular application please contact our Sales Office. Charging For Float Standby Applications Charged at 2.275 volts per cell continuous. The battery will seek its own current level and float fully charged. However, users should be aware that when charging from fully discharged, the battery can draw an initial charge current of approximately 2cA. Care should therefore be taken to ensure that this initial charge current (if ungoverned) is within the output capability of the equipment. Final charge current at 2.275 volts per cell is typically between 0.0005cA to 0.004cA. Charging For Cyclic Applications See 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. WARNING! The battery type NP65-12I must never be installed permanently suspended by their handles; they are not designed for this purpose. General Specifications
