Operating principle:positive pole is composed mostly of active carbon with strong adsorbability,big internal surface area and low internal resistance and a little of manganese powder, which can adsorb oxygen from the air.Oxygen reacts with the high purity zinc of negative pole, which can produce current. Electrolyte’s ingredient is ammonia chloride.Housing uses polyvinyl chloride.
Maintenance-free: Safe utilization.It doesnot contain any corrosive liquid.No need to add any liquid. Before using, tear off the sealed tape.
High energy density:about 377Wh/kg-676 Wh/kg .
Environment protection:It doesnot contain heavy metals, such as, mercury, cadmium and etc, which greatly reduces the waste.
Quality warranty: Due to using a new structure, it is suitable for mechanized production .The loss of the storage power is low.
Stable voltage: Due to the special ingredient, voltage is stable and very suitable for navigation light.
Long life span:in the normal condition,one 3QR40-2(4V/200Ah)zinc-air battery can use one year for a single-flash navigation light.
Mostly install in light equipments of river, lake, coastal navigation lights, lighthouses, buoys, signal lamps and controlling equipments of railway transportation. It can also be used in the controlling equipment of no alternating current.
