Contact SupplierZero-maintenance batteries have revolutionized the lead battery industry. One of the key components is a special filter disc. These are porous discs with perfectly tailored pore size and porosity press fitted into the Cap.
Key Functions
Flame Arresting :  In an event of sparking outside a battery, they prevent the propagation/ ingress of flame from outside to inside by the use of a matrix of uniform openings that are carefully constructed to quench the flame by absorbing the head of the flame. This provides an extinguishing barrier to the ignited flame.
Zero Top-Up : Small & uniform pores along with the water repellent properties prevents depletion of electrolyte through the pores.
Venting : Tailored pore size and pore volume ensures controlled venting of gases, heat developed especially during charging, preventing the build-up of gases that can otherwise lead to explosion.
