Product details

The CSB HR1234W belongs to the HR series pure lead high-rate discharge battery line. It is a 12V valve regulated sealed lead acid battery utilizing Absorbent Glass Mat (AGM) technology, achieving a gas recombination efficiency of up to 99%. It is primarily intended for lower-output UPS and rapid-discharge backup applications, with the official application area being data center uninterruptible power supplies. Nominal capacity is 34W @15min-rate (1.67 VPC @25°C), with a nominal voltage of 12 Vdc. The 15-minute power is 34.3 W/cell (1.67 VPC @25°C), and the 5-minute power is 73.0 W/cell. Maximum discharge current is 130 A, maximum charge current is 3.40 A, internal resistance is 19.0 mΩ, and short-circuit current is 349 A. Dimensions are length 150.9±2.0 mm, width 64.8±1.0 mm, height 98.6±1.0 mm, and weight 2.50 kg (5.51 lb). The terminal uses F2-Faston Tab250. The case material is ABS (UL 94-HB), with a flame-retardant (94-V0) version available upon request. Float charge voltage is 13.5 - 13.8 Vdc/battery (25°C), and equalization charge voltage is 14.4 - 15.0 Vdc/battery (25°C). Operating temperature: nominal 25°C, discharge -15°C to 50°C, charge/storage -15°C to 40°C. Design life is up to 5 years under float charge at 25°C, and 3-5 years under the Eurobat (20°C) standard. Self-discharge is less than 10% after 90 days of storage at 25°C, with a maximum storage of 6 months; fully charge before use, and recharge in advance if storage temperature exceeds 25°C. This battery meets the IEC 61056-1/2:2012 standard and is recognized under UL1989 (MH14533). With its maintenance-free design and pure lead construction, it is suitable for data center UPS and other applications requiring high-rate discharge and float backup.
