Product details

The CSB HR1234W is a 12V valve-regulated sealed lead-acid battery featuring Absorbent Glass Mat (AGM) technology with a gas recombination efficiency of up to 99%. It is a high-rate discharge pure lead battery in the HR Series. This series was developed for lower-output UPS systems and backup power applications requiring rapid discharge, with data center uninterruptible power supplies as the officially designated application. 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). The 5-minute power is 73.0 W/cell, and the 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. Weight is 2.50 kg (5.51 lb), with dimensions of 150.9±2.0 mm in length, 64.8±1.0 mm in width, and 98.6±1.0 mm in height. The terminal is F2-Faston Tab250. The case material is ABS (UL 94-HB), with a flame-retardant (94-V0) version available upon request. For charging parameters, the float voltage is 13.5 - 13.8 Vdc/battery (25°C), and the equalize voltage is 14.4 - 15.0 Vdc/battery (25°C). Operating temperature range: nominal 25°C, discharge -15°C to 50°C, charge/storage -15°C to 40°C. Under 25°C float conditions, the design life is up to 5 years, and the Eurobat (20°C) standard is 3-5 years. Self-discharge performance: less than 10% after 90 days at 25°C, with storage up to 6 months; a full charge is required before use. If storage temperature exceeds 25°C, recharge should be performed earlier. The battery meets IEC 61056-1/2:2012 standards and is UL1989 recognized (MH14533). Its maintenance-free design and pure lead construction make it well suited for data center UPS and other applications requiring high-rate discharge and float standby power.
