Santak A12-425W UPS Battery 12V425.3W Valve-Regulated Lead-Acid Battery

Product details

As the core energy storage unit of UPS power systems, the Santak ARRAY A12-425W lead-acid battery redefines power protection standards. This 36.5kg 12V battery integrates a high-power output capability of 425.3W/15 minutes within a compact 559×125×227mm space, thanks to its groundbreaking thin-plate pure lead technology—by compressing plate thickness by 30% and enhancing lead purity, it doubles the reaction contact area and improves charging efficiency by 40% compared to traditional AGM batteries.In field tests at a bank data center in Shenzhen, the battery maintained 97% capacity stability over three years in a 45°C high-temperature environment, attributed to its unique grid crystal structure that controls self-discharge at 0.06%/month, retaining 90% charge even after two years of storage without power. The front-mounted M6 terminal design enables maintenance personnel to complete the series connection of 40 units in just 15 minutes, while its ultra-low internal resistance of 4mΩ makes it particularly suitable for critical scenarios requiring millisecond-level responses, such as rail transit signal systems and petrochemical DCS control.When paired with Santak Castle series UPS, its 110Ah@C10 capacity configuration supports medical CT equipment for 8 hours of continuous scanning. The 94-V0 fireproof rating of the casing, validated by UL Lab's 2000℃ glow-wire test, provides financial core rooms with fire protection compliant with GB50016 standards. Currently, this model has been successfully deployed in a 24/7 unmanned production line at a smart factory in the Yangtze River Delta, achieving three years of zero-failure operation under extreme temperatures of 80℃.
