BATER lead acid batteries POPzS type for renewable energy

Bater popzsBater is a manufacturer of the highest quality stationary lead acid batteries with a positive tubular plate POPzS type in containers made of polypropylene, with lifetime of over 1500 cycles destined for solar, wind and hybrid power plants. We manufacture POPzS cells and stands using the latest technological developments. Our batteries are long-lived, dependable and cheap. Due to properly constructed cells the need for refilling water loses has been reduced. This reduces maintenance costs.

Our batteries are built from:

  • The highest quality wet acid cells produced in BATER plant in Gliwice,
  • Tray covered with polyethylen coatings of the highest corrosion resistance manufactured in BATER plant in Warsaw.

Key features of classic POPzS batteries manufactured by BATER are:

  • a perfect cycling – life in cycling amounts to 1500 cycles at 80% depth of discharges,
  • a low internal resistance value by applying the highest quality components (including separators) of reputable world manufacturers,
  • a low level of self- discharge (<3% /month) is a result of the highest quality components (including guntled) of the world’s leading manufacturers and special alloys,
  • electrolyte level quick and easy to control by translucent jars,
  • a couple of years topping-up interval with recombination plug,
  • the highest level of safety and mechanical resistance of battery,
    – transparent battery cell jar produced by the leading European manufacturer made of polypropylene is resistant to high and low temperature,
    – lids with dependable seals of pole pins to prevent the decrease of electrolyte,
    – polyethylene coating applied by the fluidization of trays is resistant to shock, acid and every weather condition,
    – high quality flexible connectors and screws connecting cells in the battery are fully insulated and provide full protection against short circuits,

BATER batteries have a high degree of efficiency, as a consequence:

  • we lower the value of floating current and minimize energy losses generated during operation of the battery,
  • we shorten charging time, increasing the availability of a battery, thus, reducing the cost of battery charging,
  • we lower operating costs.

The use and characteristics of POPzS batteries

Stationary POPzS batteries are used for energy storage in solar, wind and hybrid power plants. Characteristics of the battery life in the solar system is very different from a classic stationary battery. In solar system the battery is the energy storage, which is used at night, with no power from solar panels. Thus, in practice it is cycling with loading during the day and discharging at night. Bater’s response to the needs of solar applications is the development of new types of cells well adapted to the way of working through the use a special type of separator and special additives to plates improving electrical parameters and life of cell.


  • positive plates
    The grid of the tubular positive plate consists of several lead spines which are joined together by the upper frame. A special lead alloy which is used for positive plate with the addition of substances preventing the creation of crystalline structures. The core is die cast. This provides homogeneity of lead alloy in the whole core. Positive plate is tubular, which means that the condensed active mass (PbO2) is placed in special tubes (guntlets) cured by impregnation and sealed from the bottom with a plug from polyester fibers. This construction provides excellent penetration of electrolyte through the walls of tubes, while preventing the active mass from dropping to the bottom of the container. The tubes are filled on wet which ensures homogeneity and repeatability of cells measurements,
  • negative plates
    is made of the technology guaranteeing high porosity active mass. Negative plate grids are die cast from special lead alloy with the addition of substances preventing from the creation of crystalline structures. This provides homogeneity of lead alloy in the whole grid. Plates are inserted into a special mesh of Sireg production to prevent active mass from dropping,
  • separators
    High reputable manufacturer (Daramic) separators insulating positive plates from negative ones are made of microporous polyethylene with low electrical resistance. They are characterized by high resistance to sulfuric acid, high temperature and aging processes,
  • poles
    Poles made of corrosion-resistant alloy of lead with a brass core reducing fastness and increasing the value of maximum current,
  • container and  lid
    The containers is made of translucent plastic and the lid of gray high-resistant polypropylene. Acid-resistant rubber seals around the external terminals prevent the electrolyte loss during transport and operation,
  • standard recombination plugs
    Recombination plugs prevent hydrogen emission to the environment which is the protection against explosion, virtually eliminating the need to refill the water and reduces the battery room ventilation requirements to the level of VRLA batteries. On request, alternatively, we also equip the cell with  ceramic plugs. Plugs enable gas excess to escape from the interior of the cell and protect against penetration of flame to the cell,
