Modern data centers pursue automated and lightweight operation and maintenance, and maintenance-free valve-regulated  lead-acid batteries perfectly fit this development demand. Different from traditional storage batteries, the new-generation lead-acid batteries adopt a fully sealed structure with no electrolyte leakage risk, requiring no regular liquid replenishment and acidity detection, which greatly reduces manual operation and maintenance workload. They have excellent charge acceptance, overcharge resistance and high consistency, enabling stable grouped operation and adapting to the 24-hour uninterrupted power supply mode of data centers. Daily operation only requires simple inspection of appearance and voltage parameters with an extremely low failure rate. The minimalist operation and maintenance mode effectively reduces labor costs and fault troubleshooting pressure, suitable for large-scale and intensive energy storage backup deployment in data centers.
