Characteristics:
  ·Large capacity, high ratio energy
        Adopt special craftworks, the capacity is bigger than 100%，ratio energy reach 35—40Wh/Kg
  ·Low natural discharging rate
        Adopt new alloy, reticulate ledge structure, hyperpure electrolyte. natural discharging rate is low, and dehydration is little.
  ·Long circulatory life
        Adopt high-powered prescription, and has characteristic of long life.Under the common circumstance of 25℃, it can be used more than 360 times. The circulatory times can reach more than 600 times if it is used and maintained in the light of regulation.
  ·Secure and Reliable
        Adopt particular designation and injecting valve with pipelining face. The life is long and the security is excellent.
  ·Sealed and leak-tight structure:
        The battery can be used in any direction (except the inversion). Its virtues include not only sealed valve-controlling but also maintenance.
  ·Optimum design
        Adopt design of button style which will make the maintenance of accumulator easier. Regular maintenance will prolong the life 50%—100% or more.
  ·Variety using forms:
        Include both floating charge and duty-cycle operation.
  ·Recommended charging pattern:
        Three-stagewise charge
