Product details

For data center uninterruptible power supplies and similar scenarios, CSB HR1221W can provide short-term high-power backup support; the officially listed application is data center UPS, and it is also used for lower-output UPS and backup power requiring rapid discharge. This model belongs to the HR series high-rate discharge pure lead battery, uses AGM technology and pure lead construction, and the product itself is a 12V valve-regulated sealed lead-acid battery. In terms of power performance, at 1.67 VPC and 25°C, nominal capacity is given as 21W at the 15-minute rate; the 5-minute rate power is 52.5 W/cell, and the 15-minute rate power is 25.0 W/cell. This design is well suited for float standby applications requiring short-term high power output. In terms of electrical specifications, at 25°C the float voltage range is 13.5 to 13.8 Vdc/battery, and the equalization voltage range is 14.4 to 15.0 Vdc/battery; maximum charge current, maximum discharge current, short-circuit current, and internal resistance are 2.10 A, 90 A, 249 A, and 23.0 mΩ, respectively. Nominal operating temperature is 25°C; discharge can be performed from -15°C to 50°C, and charging and storage are permitted from -15°C to 40°C. In terms of self-discharge, residual capacity after standing at 25°C for 90 days is greater than 90%; it can be stored for up to 6 months, must be fully charged before use, and if storage temperature exceeds 25°C, it should be charged earlier. In terms of construction, the terminal is F2-Faston Tab250, the case material is ABS (UL 94-HB), and a flame-retardant (94-V0) version can be provided on request. Dimensions: length 90.0±1.0 mm, width 70.0±1.0 mm, height 106.1±1.5 mm; weight approximately 1.80 kg (3.97 lb). When float-charged at 25°C, design life can reach 5 years; according to the Eurobat standard, it is 3 to 5 years at 20°C. This battery uses a valve-regulated sealed lead-acid construction and is maintenance-free; through AGM technology, gas recombination efficiency can reach up to 99%, making it suitable for high-rate UPS and float standby power supplies. It is manufactured in accordance with IEC 61056-1/2:2012 and has been recognized under UL1989 (MH14533).
