What CellXPro can do

Gasket: Made from CellXPro™ materials, the main gasket creates a secure seal against external elements such as moisture, while preventing electrolyte leakage. This ensures operational reliability and promotes environmental safety.
Sealing pin: The sealing pin provides preliminary and final sealing of the electrolyte filling opening, ensuring precise control and minimizing the risk of contamination.
Insulator: The patented CellXPro™ insulator is vital for maintaining electrical isolation. It prevents contact between internal components, such as the pole and cap, ensuring electrical safety and operational efficiency.
