The combination of sealed construction and Yuasa’s unique electrolyte suspension system allows operation in any Technical Features orientation, with no loss of performance or fear of electrolyte Sealed Construction leakage. Yuasa’s unique construction and sealing technique Valve Regulated Design ensures no electrolyte leakage from case or terminals. The batteries are equipped with a simple, safe, low pressure Electrolyte Suspension System venting system which releases excess gas and automatically All NP batteries utilize Yuasa’s unique electrolyte suspension reseals should there be a build up of gas within the battery due to severe overcharge. Note. On no account should the battery be system incorporating a microfine glass mat to retain the charged in a sealed container. maximum amount of electrolyte in the cells. The electrolyte is retained in the separator material and there is no free General electrolyte to escape from the cells. No gels or other Specifications contaminants are added. Control of Gas Generation Nominal Capacity (Ah) NP1.2-6 The design of Yuasa’s NP batteries incorporates the very latest 20hr to 1.75vpc 30ºC 1.2 oxygen recombination technology to effectively control the generation of gas during normal use. 10hr to 1.75vpc 20ºC 1.1 5hr to 1 .70vpc 20ºC 1 Low Maintenance Operation 1 hr to 1 .60vpc 20ºC 0.7 Due to the perfectly sealed construction and the recombination of gasses within the cell, the battery is almost Voltage 6 maintenance free.

Long Cycle Service Life Operating Temperature Range Depending upon the average depth of discharge, over a The batteries can be used over a broad temperature range thousand discharge/charge cycles can be expected. permitting considerable flexibility in system design and location. Float Service Life Charge – 15°C to 50°C The expected service life is five years in float standby Discharge – 20°C to 60°C applications. Storage – 20°C to 50°C (fully charged battery) 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.
