  • Lead alloy with low calcium minimizes gassing and extends the life of the grid.
  • Through unique active material recipes, plates after undergoing curing and tank formation provide outstanding energy density and ensure the quality of the battery.
  • Using brass coated lead alloy battery terminals minimizes the impedance of connecting cells inside.
  • The case made of ABS resin and cells kept under internal pressure protects from outer shock or impact.
  • Micro-porous AGM separator completely absorbs and retains electrolyte under the pressured cell design.
  • Electrolyte sufficiently serves for electrochemical reactions in battery but never spills.
  • Battery cases are sealed in epoxy and cells are covered with vents to avoid cell contamination with the atmosphere and serve for internal oxygen reaction.
  • With very little gas evolution, the water loss is minimized and service life is extended. Excess pressure and gas will be released which ensures safety.
  • Vent design is certificated by UL.
