Product details

The CSB XHT9000FT is a 12V front terminal valve-regulated sealed lead-acid battery belonging to the XHT series. Its core design features an absorbed glass mat (AGM) separator and proprietary grid, achieving a gas recombination efficiency of up to 99%, and it is a maintenance-free type. This series is positioned around pure lead and high-temperature resistance, purpose-built for critical power tasks in harsh environments, with the officially listed application being data center uninterruptible power supply (Datacenter UPS). In terms of electrical specifications, this battery has a voltage of 12 Vdc and a nominal capacity of 9000W @ 5min-rate (9.60V per PCS @ 25°C). The per-cell power reaches 2069.83 W/cell (30 seconds 1.67 VPC @ 25°C), 1403.33 W/cell (5 minutes 1.67 VPC @ 25°C), and 907.67 W/cell (15 minutes 1.67 VPC @ 25°C) respectively. The maximum charging current is 75.00 A, the maximum discharging current is 1900 (5 seconds), the short-circuit current is 5102 A, and the internal resistance is 1.86 mΩ. The float charging voltage range is 13.5 to 13.8 Vdc/battery (25°C), and the equalization charging voltage range is 14.4 to 15.0 Vdc/battery (25°C). Structurally, the case is made of PC-ABS flame-retardant material (UL 94-V0), the terminal specification is I2 thread lead alloy terminal to accept M6 bolt, and the terminal torque range is 51.7±10.3 Kgf∙cm, 44.9±9.0 Lbf∙in, or 5.1±1.0 N∙m. Its dimensions are 558.0±2.5 mm in length, 126.0±1.5 mm in width, and 325.0±2.5 mm in height, with an overall weight of 71.1 kg (156.74 lb.). In terms of environmental adaptability, the discharge operating temperature range is from -40°C to 65°C, and charging and storage also cover -40°C to 65°C. The design life exceeds 12 years under 25°C float charging, and can reach 10 years under 35°C float charging. Self-discharge performance is less than 10% after 90 days of storage at 25°C, with a storage capability of 6 months, which can be extended to 10 months with equalization charging; the battery must be fully charged before being put into service, and requires advance charging when the storage temperature exceeds 25°C. This product is manufactured in accordance with IEC 60896-21/22:2004, UL1989 (MH14533), and UL 1973 Recognized (MH66728) standards.
