Product details

CSB officially positions the HR1218W for small-output UPS and fast-discharge backup power applications, and it belongs to the HR series of high-rate discharge pure lead batteries. In data center uninterruptible power supply systems, this model can provide short-duration high-rate backup power to critical loads; thanks to its maintenance-free design and compact size, it is easy to integrate into UPS cabinets with limited space. Capacity and power are rated as follows: at 1.67 VPC @25°C, nominal capacity is expressed as 18W at the 15-minute rate; the 5-minute rate power is 38.1 W/cell, and the 15-minute rate power is 17.8 W/cell. These characteristics make it suitable for backup power applications requiring short-duration high-power output. Mechanical dimensions: length 150.9±2.0 mm, width 51.0±1.0 mm, height 98.6±1.0 mm, weight approximately 1.53 kg. Operating temperature ranges include: nominal 25°C; discharge -15°C to 50°C; charge and storage -15°C to 40°C. Design life is up to 5 years under float charging at 25°C; under the Eurobat standard, 3 to 5 years at 20°C. Electrical parameters: nominal voltage 12 Vdc, maximum charge current 1.80 A, maximum discharge current 130 A, internal resistance 28.5 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. Terminal type is F2-Faston Tab250. When stored for 90 days at 25°C, the self-discharge rate is below 10%, and it can be stored for up to 6 months; fully charge before use, and if storage temperature is above 25°C, charge earlier. In terms of type, the HR1218W is a 12V valve-regulated sealed lead-acid battery, using absorbent glass mat technology, with gas recombination efficiency up to 99%, and a maintenance-free design. The positive and negative plates use pure lead construction and a proprietary formulation, which helps high-rate discharge performance. The case material is ABS, meets the UL 94-HB flame retardancy rating, and a 94-V0 flame-retardant version can also be provided on request. The battery complies with IEC 61056-1/2:2012 and is recognized under UL1989. When using the HR1218W, follow the specified charging voltage and temperature ranges to ensure performance and service life.
