WINNER AJAX includes a full range of stand by low maintenance batteries designed to satisfy the demands of long life installations with high reliability and requires medium and long duration discharge. They perform excellent for a wide range of temperatures from -20°C up to +50°C.

WINNER AJAX cells are manufactured with highest quality robust tubular positive plates, which ensure excellent characteristics, long life for stand by applications and the highest endurance under heaviest loading cycles.

The specifications of the WINNER AJAX OPzS cells make the batteries ideal for a wide range of applications, such as telecommunications, signal systems and emergency lighting, power systems, energy storage in wind and solar power systems, etc.

Positive plates: The positive electrode is composed of a tubular type plate. Special alloy grids are casted in die-casting machines that are inserted into special gauntlet tubes made of polyester fibres. The spaces between the bars of the grid and the walls of the tubes are filled in with the lead dioxide active material.

Negative plates: The negative electrode is a pasted lead grid plate. The active material made from the lead oxide is pasted into a cast lead alloy grid, which serves both as a carrier of the active material and as an electrical conductor. The formation process converts the paste into pure lead.

Separator: A separator is made from micro porous material with high porosity and low electric resistance, which ensures a good flow of the ions in the electrolyte from one electrode to the other.

Case: The containers are made with styrene acrylonitrile (SAN), which is transparent, impact, corrosion proof, flame retardant, acid and shock resistant material. Due to the transparent containers, the electrolyte level is clearly visible; the maximum and minimum levels are marked by the silk-printed label of the container side.

Connectors: Flexible copper connectors, fully insulated and protected, tightened to the leak proof screw type of the high safety terminals.

Vent plugs: The filling holes in the cell lids are fitted with porous ceramic plugs that filter out any drops of electrolyte from the escaping gases.
