Absorbing glass fiber separator (AGM separator) is an important part of valve regulated lead-acid battery. Its performance and dosage directly affect the technical performance of the battery, especially the service life of the battery.

Whether it is a valve-regulated sealed lead-acid battery using glass fiber diaphragm (hereinafter referred to as AGM sealed lead-acid battery) or a valve-regulated sealed lead-acid battery using colloidal electrolyte (hereinafter referred to as colloidal-sealed lead-acid battery), they all use the principle of cathode absorption to make The battery is sealed.
