Product details

The CSB HR1218W is a 12V valve-regulated sealed lead-acid battery belonging to the HR series of high-rate discharge pure lead batteries, officially positioned for small-output UPS and fast-discharge backup applications. Its nominal capacity is expressed as an 18W 15-minute rate at 1.67 VPC @25°C, with a 5-minute rate power of 38.1 W/cell and a 15-minute rate power of 17.8 W/cell, suitable for backup occasions requiring short-time high-power output. This battery adopts a valve-regulated sealed lead-acid structure and absorbed glass mat technology, with gas recombination efficiency up to 99%, and is a maintenance-free design. The positive and negative plates use pure lead construction and a proprietary formula, helping high-rate discharge performance. The case material is ABS, meeting UL 94-HB flame retardant rating, and a 94-V0 flame retardant version can also be provided on request. The battery is built to comply with IEC 61056-1/2:2012 standards and is UL1989 recognized. In terms of electrical parameters, the HR1218W has a nominal voltage of 12 Vdc, maximum charge current of 1.80 A, maximum discharge current of 130 A, and internal resistance of 28.5 mΩ. The float charge voltage is 13.5 to 13.8 Vdc/battery (25°C), and the equalizing charge voltage is 14.4 to 15.0 Vdc/battery (25°C). The terminal type is F2-Faston Tab250. The self-discharge rate is less than 10% after 90 days at 25°C, and it can be stored for up to 6 months; it must be fully charged before use, and if the storage temperature is above 25°C, it should be charged earlier. In terms of mechanical dimensions, the battery is 150.9±2.0 mm long, 51.0±1.0 mm wide, 98.6±1.0 mm high, and weighs approximately 1.53 kg. Operating temperature range: nominal 25°C, discharge -15°C to 50°C, charge and storage -15°C to 40°C. The design life can reach 5 years under 25°C float charge conditions, and 3 to 5 years at 20°C under the Eurobat standard. The HR1218W is mainly used in data center uninterruptible power supply systems, providing short-time high-rate backup power for critical loads. Its maintenance-free characteristics and compact size facilitate integration into UPS cabinets with limited space. The specified charge voltage and temperature range should be followed during use to ensure performance and life.
