The zinc-air battery was discovered in the early nineteenth century, but did not find its first commercial use until the 1930s when large industrial-type cells were constructed for railway signaling. The development of the thin and efficient air cathode used in today’s zinc-air cells occurred in the early 1970s. The world of zinc-air today includes button cells, batteries, and a number of customized battery packs. Zinc-air delivers the highest energy density of any commercially available battery system, and at a low operating cost. This advantage is derived from its use of atmospheric oxygen as the cathode reactant. It allows the zinc-air cell to be filled with more zinc "fuel", which is the only material consumed during discharge. This increased amount of anode material enables the cell to offer up to 5 times more capacity than conventional zinc anode systems which must contain their oxidant within the cell. For example, alkaline cells store oxygen in the form of manganese dioxide, which comprises about 60% of the cell weight. Most batteries contain roughly the same amount of anode material as cathode material, so their service life is limited by whichever is consumed first.
This technology is best suited for applications where the devices demand continuous low power load, isolated from the network, for a medium to long term period of time. For instance, this technology is well suited to supply continuously till 5,4 watts load in the 1,5 to 24 V voltage range, up to 2 years autonomy.

ZINC AIR ALKALINE Batteries manufactured by Cegasa P.E.
The batteries are made with a specially formulated manganese dioxide cathode (manufactured by Cegasa P.E.) that is continuously regenerated by the oxygen from the air. This fact makes the cells use a very small amount of cathodic active material compared to others conventional alkaline batteries. The great advantage is that a larger amount of anodic material can be stored in the cell and more energy is available.
As result the Zinc Air Alkaline Battery from Cegasa P.E. is the battery with highest capacity of the market, competitive cost and minimum environmental impact.
Constant output voltage, meaning constant performance
Constant output voltage means constant performance all along their lifes increases their efficiency, reduces number of changes, and minimizesr enviromental impact.
Exceptional Energy Density compared with other technologies, that is longer life, compact and light weight battery
Energy delivered Comparison among Alkaline, Saline y Zinc Air Alkaline
Saline 4R25 (4x1V-5/7/9Ah) Energy = 4V x 5Ah = 20 Wh
Standard Alkaline 4LR20 (4x1.05V-32Ah) Energy = 4,2V x 32Ah = 134,4 Wh
Zinc Air Cegasa 4AS2/50 (5,4V-50Ah) Energy = 5,4V x 50Ah = 270 Wh
The Best cost of energy you can find in the market due to the higher energy density of this technology
