Large-scale and standardized deployment is the construction trend of modern data centers, and lead-acid batteries are preferred solutions due to high compatibility and low maintenance. Mainstream valve-regulated sealed lead-acid batteries adopt a fully sealed design with no electrolyte leakage risk and no frequent fluid replacement, suitable for intensive computer room layout. With high product standardization, they are compatible with various UPS equipment and applicable to new and renovated computer rooms. Featuring strong working condition stability and low long-term failure rate, they adapt well to large-scale cluster deployment and support stable power supply for data centers.
