Product details

The CSB HR1224W in the HR series is a 12V valve-regulated sealed lead-acid battery with a Top Terminal design. It uses absorbed glass mat (AGM) technology, achieving gas recombination efficiency of up to 99%, and requires no routine maintenance. This series is a high-rate discharge pure lead battery, designed specifically for UPS and standby scenarios that require low output power and rapid discharge, with the officially published application area being data center uninterruptible power supplies. In terms of parameters, the HR1224W has a voltage of 12 Vdc, and a nominal capacity of 24W @15min-rate at 1.67 VPC, 25°C. At 1.67 VPC, 25°C, the 5-minute rate power reaches 54.8 W/cell, and the 15-minute rate power is 27.0 W/cell. The battery's maximum charging current is 2.40 A, short-circuit current is 260 A, and internal resistance is 20.6 mΩ. The terminal type is F2-Faston Tab250. In terms of dimensions, the HR1224W is 150.9±2.0 mm long, 51.0±1.0 mm wide, 98.6±1.0 mm high, and weighs 1.95 kg. The case material is ABS, with a flame retardant rating compliant with UL 94-HB, and a 94-V0 flame retardant case can also be provided on request. The design life can reach 5 years under 25°C float standby service, and 3 to 5 years under Eurobat standard 20°C conditions. Charging and temperature conditions are as follows: at 25°C, the float charging voltage is 13.5 to 13.8 Vdc/battery, and the equalization charging voltage is 14.4 to 15.0 Vdc/battery. The nominal operating temperature is 25°C, the discharge temperature range is -15°C to 50°C, and the charging and storage temperature range is -15°C to 40°C. In terms of self-discharge, capacity loss is less than 10% after 90 days of storage at 25°C, and it can be stored for up to 6 months, requiring a full charge before use; if the storage temperature is higher than 25°C, it should be charged sooner. The product is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 Recognized (MH14533). With its high-rate discharge characteristics and pure lead construction, it is suitable for float service scenarios requiring rapid discharge standby, such as data center UPS systems.
