Product details

The official application area points to data center uninterruptible power supplies; in scenarios requiring rapid discharge and backup power, the CSB HR1227W can handle the corresponding tasks. This model belongs to the HR series and is a 12V top-terminal valve-regulated sealed lead-acid battery. It uses absorbent glass mat (AGM) technology, with gas recombination efficiency up to 99%. Its construction uses pure lead and a proprietary formulation, targeting high-rate discharge and float standby power applications. According to its official positioning, it belongs to the high-rate discharge pure lead battery series and can be used in UPS units with relatively low output power and rapid-discharge backup applications. This battery is maintenance-free, manufactured in accordance with IEC 61056-1/2:2012, and has UL1989 recognition (MH14533). Under 25°C float-charge service conditions, design life is up to 5 years; per Eurobat (20°C), commercial life is 3 to 5 years. Nominal temperature is 25°C (77°F); the discharge temperature range is -15°C to 50°C (5°F to 122°F), and the charge and storage temperature range is -15°C to 40°C (5°F to 104°F). For self-discharge, less than 10% after 90 days at 25°C; also at 25°C, the storage limit is 6 months, and a full charge is required before use. If storage temperature exceeds 25°C, recharge sooner. Electrical parameters are as follows: voltage is 12 Vdc; at 1.67 VPC and 25°C, nominal capacity is 27W @15min-rate. Under the same 1.67 VPC and 25°C conditions, the 5-minute rate power is 53.0 W/cell, and the 15-minute rate power is 27.0 W/cell. Maximum charge current 2.70 A, maximum discharge current 130, short-circuit current 424 A, internal resistance 19.9 mΩ. At 25°C, float voltage is 13.5 to 13.8 Vdc/battery, and equalization voltage is 14.4 to 15.0 Vdc/battery. For construction, terminal type is F2-Faston Tab250, and the case is ABS (UL 94-HB); a flame-retardant 94-V0 version is also available upon request. Dimensions and weight are: length 90.0±1.0 mm, width 70.0±1.0 mm, height 106.1±1.5 mm, weight 1.97 kg (4.34 lb). With high-rate discharge performance and stable float performance, the HR1227W can be used for rapid-discharge and backup power requirements such as data center UPS; under specified float voltage and temperature conditions, it can maintain reliable operation.
