Product details
The CSB HRL1250W belongs to the HRL series and is a 12Vdc VRLA battery. This series is positioned as long life high rate pure lead batteries, developed specifically for high power data centers and UPS loads, with the official application direction being data center UPS systems. The battery utilizes valve regulated sealed design and Absorbent Glass Mat technology, achieving a maximum gas recombination efficiency of 99%, while employing pure lead construction and a proprietary formula to meet the demands of high rate UPS and float standby power applications.
In terms of capacity and power, the HRL1250W has a nominal capacity of 50W @15min-rate; at 1.67 VPC and 25°C, the 5-minute power reaches 102 W/cell, and the 15-minute power is 51.0 W/cell. Its maximum charge current is 5.0 A, maximum discharge current is 130 A, and internal resistance is 15.0 mΩ. These parameters help assess the battery's performance in short duration high power discharge scenarios.
Regarding charging parameters, at 25°C the float charge voltage is 13.5 to 13.8 Vdc/battery, and the equalize charge voltage is 14.4 to 15.0 Vdc/battery. For self-discharge, capacity loss after 90 days storage at 25°C is less than 10%, with a maximum storage of 6 months; the battery should be fully charged before use, and if storage temperature exceeds 25°C, recharge is required earlier. For operating temperature, the nominal temperature is 25°C, discharge range is -15°C to 50°C, and charge and storage range is -15°C to 40°C.
In terms of structural parameters, the HRL1250W dimensions are 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 is F2 terminal - Faston Tab 250. The case is made of ABS (UL 94-HB) material, with a flame retardant (94-V0) version available upon request. For design life, float standby service at 25°C can reach 8 years, and Eurobat (20°C) standard commercial use is 10 to 12 years.
The battery is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 recognized (MH14533). With maintenance-free design and high rate discharge capability, the HRL1250W is suitable for scenarios requiring float standby and short duration high power output such as data center UPS, providing stable backup power support for equipment.
