AGM Separator For Stationary Lead-acid Battery


Stationary batteries are a type of battery commonly used in various fields requiring static power storage and backup, such as telecommunications, data storage centers, medical facilities, and financial institutions. They serve as emergency backup power systems, providing stable and reliable power protection in case of short-term power outages.

Stationary batteries offer several advantages, including large capacity, long lifespan, high reliability, convenient maintenance, excellent safety features, and relatively low cost. To meet these requirements, they require AGM separators with high density, high strength, good elastic recovery, low impurity content, low resistance, fast capillary absorption of acid, high acid climb ability, and strong electrolyte retention ability.

We have been producing AGM separators for stationary batteries for over 20 years and has established long-term and stable partnerships with leading domestic and foreign battery manufacturers.
