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 GenerationThe 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 OperationDue to the perfectly sealed construction and the recombination of gasses within the cell, the battery is almost maintenance free.TerminalsNP batteries are manufactured using a range of terminals which vary in size and type. Please refer to details as shown.Operation in any OrientationThe 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 DesignThe 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 GridsThe 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 LifeDepending upon the average depth of discharge, over a thousand discharge/charge cycles can be expected.Float Service LifeThe expected service life is five years in float standby applications.SeparatorsThe 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 LifeThe 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 RangeThe batteries can be used over a broad temperature range permitting considerable flexibility in system design and location.
