Product details
In the UPS and data center backup power sector, the XHRL series is a high-performance extension of the HRL line, and the CSB XHRL12250W is a 12V valve-regulated sealed lead-acid battery within that series. Its high-rate output capability has been enhanced for the aforementioned applications. The absorbed glass mat (AGM) technology employed achieves 99% gas recombination efficiency, and the pure lead construction combined with proprietary elements results in an overall maintenance-free design. Its officially designated application is data center uninterruptible power supplies, capable of handling high-rate discharge and float standby requirements.
In terms of electrical specifications, this battery has a nominal voltage of 12 Vdc and a nominal capacity of 250W (1.67 VPC @25°C, 15-minute rate). The 15-minute rate power is 252.67 W/cell, and the 5-minute rate power is 463.17 W/cell (both at 1.67 VPC @25°C). The maximum charging current is 25.00 A, the maximum discharge current is 650 A, the short-circuit current is 1680 A, and the internal resistance is 4.20 mΩ. At 25°C, the float charging voltage range is 13.5 - 13.8 Vdc/battery, and the equalization charging voltage range is 14.4 - 15.0 Vdc/battery.
For terminals, this battery uses the I2 threaded lead alloy type, compatible with M6 bolts, with torque specifications of 51.7±10.3 Kgf∙cm, 44.9±9.0 Lbf∙in, or 5.1±1.0 N∙m. The case is made of PP material (UL 94-HB); a flame-retardant version (94-V0) is available upon request. The overall weight is 18.52 kg (40.82 lb), and the dimensions are 228.0±2.5 mm in length, 138.4±1.5 mm in width, and 206.3±2.5 mm in height.
In terms of service life, the XHRL12250W can last 10 years under 25°C float standby conditions and meets the very long life classification defined by the Eurobat standard (20°C), which is greater than 12 years. The operating temperature range is: nominal 25°C, -15°C to 50°C for discharge, and -15°C to 40°C for charging and storage. After standing for 90 days at 25°C, the self-discharge rate is less than 10%, and it can be stored for up to 6 months, but must be fully charged before being put into operation; if the storage temperature exceeds 25°C, a supplementary charge is required in advance.
In terms of manufacturing and certification, this battery is produced in accordance with IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533). With its high-rate discharge characteristics, it can provide reliable backup power for applications such as data center UPS systems, meeting the requirements of standby float service applications.
