  • Special grid alloy and high purity raw material ensures less gassing and less self-discharging
  • Grid refining technology and the thicker plates are used to extend the battery standby life and reduce the plate grid corrosion speed
  • Lower acid density, excess of electrolyte and larger distance between plates keeps battery at a low temperature and slows down plate grid corrosion rate
  • Using oxygen recombination technology: maintenance-free
  • ABS material: increase the strength of battery container. (Flame-retardant ABS is optional)
  • Unique vent valve design: controls water loss, prevents air and sparks from going inside
