Product details
The CSB HRL1234W belongs to the HRL series, a valve-regulated sealed lead-acid battery with 6V and 12V top terminal configurations and a nominal voltage of 12 Vdc. The series is positioned as long-life, high-rate pure lead batteries for data center and uninterruptible power supply applications with higher load requirements, with the official application area being data center uninterruptible power supplies.
In terms of capacity and power, the HRL1234W has a nominal capacity of 34W @15min-rate at 25°C, 1.67 VPC. Its power per cell at 25°C, 1.67 VPC is 75.34 W/cell at the 5-minute rate and 35.50 W/cell at the 15-minute rate. The battery's maximum charge current is 3.40 A, maximum discharge current is 130 A, short-circuit current is 367 A, and internal resistance is 17.0 mΩ.
In construction, the HRL1234W uses a valve-regulated sealed lead-acid design and absorbed glass mat technology, achieving up to 99% gas recombination and maintenance-free operation; it also uses a pure lead construction and proprietary element formulation. The case material is ABS (UL 94-HB), with a flame-retardant 94-V0 version available on request. The terminal type is F2 terminal - Faston Tab 250. The product is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 Recognized (MH14533).
In terms of dimensions and weight, the battery is 150.9±2.0 mm in length, 64.8±1.0 mm in width, and 98.6±1.0 mm in height, with a weight of 2.70 kg. Design life is up to 8 years in 25°C float standby service, and 10 to 12 years per the Eurobat (20°C) standard for commercial use. The nominal operating 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.
For charging parameters, the float charge voltage at 25°C is 13.5 to 13.8 Vdc/battery, and the equalizing charge voltage is 14.4 to 15.0 Vdc/battery. Self-discharge is less than 10% after 90 days at 25°C, and the battery can be stored for up to 6 months; it must be fully charged before use, and if storage temperature is above 25°C it should be charged sooner. This battery is suitable for high-rate UPS and float standby power applications.
