Product details

The CSB HR1234W is a 12V valve-regulated sealed lead-acid battery using absorbed glass mat (AGM) technology with gas recombination efficiency up to 99%, belonging to the HR series of high-rate discharge pure lead batteries. This series is designed for smaller-output UPS and fast-discharge standby applications, with the official application area being data center uninterruptible power supplies. In terms of specifications, the HR1234W has a nominal voltage of 12 Vdc and a nominal capacity of 34W @15min-rate (1.67 VPC @25°C). Its 5-minute power is 73.0 W/cell and 15-minute power is 34.3 W/cell (1.67 VPC @25°C). Maximum charge current is 3.40 A, maximum discharge current is 130 A, short-circuit current is 349 A, and internal resistance is 19.0 mΩ. The battery weighs 2.50 kg (5.51 lb) and measures 150.9±2.0 mm in length, 64.8±1.0 mm in width, and 98.6±1.0 mm in height. Terminal type is F2-Faston Tab250. The case material is ABS (UL 94-HB), with a flame-retardant (94-V0) version available upon request. For charging, float charge voltage is 13.5 - 13.8 Vdc/battery (25°C) and equalizing charge voltage is 14.4 - 15.0 Vdc/battery (25°C). Operating temperature range is: nominal 25°C, discharge -15°C to 50°C, charge/storage -15°C to 40°C. Design life is up to 5 years at 25°C float charge, and 3-5 years per Eurobat (20°C). For self-discharge, less than 10% after 90 days at 25°C, can be stored for up to 6 months, requires full charge before use, and should be charged earlier if storage temperature exceeds 25°C. This battery complies with IEC 61056-1/2:2012 and is recognized under UL1989 (MH14533). Its maintenance-free design and pure lead construction make it suitable for applications requiring high-rate discharge and float standby such as data center UPS.
