New FLA batteries SOPzS type for renewable energy

Bater is a manufacturer of complete stationary FLA batteries  with positive tubular plate SOPzS type consistent with DIN40736  with lifetime of over 1500 cycles destined for solar, wind and hybrid power plants. We manufacture SOPzS 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. Additionally – the use of the bidirectional or standard recombination plug patented by Bater virtually eliminates the necessity of refilling water loses and reduces the requirements for room ventilation to the level of VRLA battery, which significantly reduces maintenance costs and eliminates the need for mechanical ventilation in the battery room.

Our batteries are built from:

  • the highest quality lead acid cells produced in BATER plant in Gliwice,
  • stands covered with polyethylene coatings of the highest corrosion resistance manufactured in BATER plant in Warsaw,
  • patented recombination plugs eliminating the emission of hydrogen and water loss manufactured in BATER plant in Warsaw.

Key features of OPzS batteries manufactured by BATER are:

  • a perfect cycling – life in cycling amounts to 1500 cycles at DOD 80%,
  • low internal resistance value by applying the best components (including separators) of reputable global manufacturers,
  • low self-discharge<3%/month,
  • extremely low water use through the use of low-antimony alloys and patented recombination plugs (need for refill once every 12-15 years)
  • rapid and straightforward control of electrolyte level through transparent containers,
  • the highest level of safety and mechanical resistance of battery,
    • battery cell containers produced by the leading European manufacturer are made of SAN plastic resistant to high and low temperature,
    • lids with dependable poles seals to prevent the decrease of electrolyte,
    • the basis for batteries are made of steel and covered by polyethylene coating applied by fluidization. The coating is resistant to shock, acid and any weather condition,
    • the highest 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 SOPzS batteries

Stationary SOPzS batteries are used for energy storage in solar, wind and hybrid power plants. Characteristics of the battery life in 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. Laboratory results supported by years of operating experience have shown that in the cycle cells with the content of antimony in the core of the positive plate at 6% work the most efficiently. Higher antimony content than in standard OPzS LA batteries (low-antimonic) provides better stabilization of active mass and increased resistance to deep discharge, eliminating the risk of positive plate’s core degradation causing early loss of capacity. 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 of cores containing 6% of antimony and a special type of separator improving electrical parameters and life of cell. SOPzS cells in casings made of transparent SAN plastic are the most advanced technical solution.  Cells are equipped with bidirectional or standard recombination plugs patented by Bater, which virtually eliminates the need for water refilling and reduces the requirements for ventilation of rooms (on request we can provide cells with any type of standard plug).
