MOQ :
1. Special grid alloy and high purity raw material ensure less gassing, less self-discharging 2. Grid refining technology and the thicker plates are used to extend the battery standby life and reduce the plate grid corrosion speed 3. Using oxygen recombination technology: maintenance-free 4. Lower acid density, excess of electrolyte and larger distance between plates to keep battery at low temperature and slow down plate grid corrosion speed 5. ABS material: increase the strength of battery container. (Flame-retardant ABS is optional) 6. Unique vent valve design: control water losing, prevent air and spark going inside
