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** ## **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. ## **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. ## **General** ## **Specifications** ## **Layout** |**Nominal Capacity (Ah)**|**NP4-12**| |---|---| |20hr to 1 .75vpc 30ºC|4| |1 0hr to 1 .75vpc 20ºC|3.7| |5hr to 1.70vpc 20ºC|3.4| |1 hr to 1 .60vpc 20ºC|2.4| |Voltage|12| |Energy Density(Wh.L.20hr)|75| |Specific Energy(Wh.kg.20hr)|27| |Int.

Charge – 15°C to 50°C Discharge – 20°C to 60°C 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.
