Product details
The CSB HRL1250W is a 12Vdc valve-regulated lead-acid battery belonging to the HRL series. This series is a long-life high-rate pure lead battery series designed for high-power data center and UPS loads, with an official application area of data center uninterruptible power supplies. The battery uses a valve-regulated sealed structure and absorbed glass mat technology, with a gas recombination efficiency of up to 99%, and features pure lead construction and a proprietary formula, suitable for high-rate UPS and float standby power applications.
In terms of capacity and power, the HRL1250W has a nominal capacity of 50W @15min-rate, with a 5-minute power of 102 W/cell and a 15-minute power of 51.0 W/cell at 1.67 VPC, 25°C. The battery's maximum charge current is 5.0 A, maximum discharge current is 130 A, and internal resistance is 15.0 mΩ. These parameters can be used to evaluate its performance in short-duration high-power discharge applications.
For charging, at 25°C the float charge voltage is 13.5 to 13.8 Vdc/battery, and the equalizing charge voltage is 14.4 to 15.0 Vdc/battery. For self-discharge, capacity loss is less than 10% after 90 days of storage at 25°C, and it can be stored for up to 6 months; it must be fully charged before use, and if stored above 25°C it should be charged sooner. For operating temperature, the nominal temperature is 25°C, the discharge range is -15°C to 50°C, and the charge and storage range is -15°C to 40°C.
Structurally, the HRL1250W has dimensions of length 151.0±2.0 mm, width 98.0±1.0 mm, height 100.3±1.5 mm, weight 3.90 kg, and terminal type F2 terminal - Faston Tab 250. The case material is ABS (UL 94-HB), and a flame-retardant (94-V0) version is available upon request. For design life, it can reach 8 years in 25°C float standby service, and 10 to 12 years per Eurobat (20°C) standard commercial use.
The battery is manufactured to IEC 61056-1/2:2012 and recognized under UL1989 (MH14533). With its maintenance-free design and high-rate discharge capability, the HRL1250W is suitable for applications such as data center UPS requiring float standby and short-duration high-power output, providing stable backup power support for equipment.
