Product details
The XHRL12250W is a 12V Valve Regulated Sealed Lead Acid Battery from CSB, part of the XHRL series. As an upgraded version of the HRL series, the XHRL series delivers stronger high-rate output in UPS and data center applications. The battery uses Absorbent Glass Mat (AGM) technology with 99% gas recombination efficiency, a pure lead construction with proprietary elements, and a maintenance-free design. Its officially designated use is data center uninterruptible power supplies, suitable for high-rate discharge and float charge standby applications.
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 5-minute rate power is 463.17 W/cell, and the 15-minute rate power is 252.67 W/cell (1.67 VPC @25°C). Maximum charge current is 25.00 A, maximum discharge current is 650 A, short-circuit current is 1680 A, and internal resistance is 4.20 mΩ. Float charge voltage is 13.5 - 13.8 Vdc/battery (25°C), and equalization charge voltage is 14.4 - 15.0 Vdc/battery (25°C).
For terminals, it uses I2 threaded lead alloy terminals compatible with M6 bolts, with a terminal torque of 51.7±10.3 Kgf∙cm or 44.9±9.0 Lbf∙in or 5.1±1.0 N∙m. The case material is PP (UL 94-HB), with a flame-retardant version (94-V0) available upon request. Weight is 18.52 kg (40.82 lb), and dimensions are length 228.0±2.5 mm, width 138.4±1.5 mm, height 206.3±2.5 mm.
For design life, it can reach 10 years under float charge standby service at 25°C; according to the Eurobat standard (20°C), the life classification is very long life, greater than 12 years. Operating temperature range: nominal 25°C, discharge -15°C to 50°C, charge/storage -15°C to 40°C. Self-discharge rate at 25°C is less than 10% after 90 days, and it can be stored for up to 6 months; it must be fully charged before use. If storage temperature exceeds 25°C, recharge is required in advance.
This battery is manufactured according to IEC 60896-21/22:2004 and is UL1989 recognized (MH14533). With its high-rate discharge characteristics, it is suitable for applications requiring high backup power reliability such as data center UPS, and can meet the needs of float charge standby applications.
