  • The plate is with the structure of big grid and block, and is made of special alloy through special process of quadric basic lead sulfate, which improves specific energy of the battery and prolongs the cycle service life
  • Positive grid is made of special multi alloy, which overcomes the shortcomings of early capacity loss. It has long service life under both float  charge and cycle utilization
  • Add special additives to the positive and negative plates, improve the utilization of active material and charging acceptability
  • High-purity electrolyte and special additives
  • Unique assembled maze seal structure of terminal (patented technology) ensures the safety and reliability of seal
