Product details

The HR1232W is a 12V top-terminal Valve Regulated Sealed Lead Acid battery in CSB's HR series. It features pure lead construction and a proprietary element formula, along with Absorbent Glass Mat (AGM) technology, achieving a gas recombination efficiency of up to 99% in a maintenance-free design. This series focuses on high-rate discharge performance and is designed for UPS systems with lower output power and backup scenarios requiring rapid discharge. Its official application is data center UPS. In terms of specifications, the HR1232W has a voltage of 12 Vdc and a nominal capacity of 32W @15min-rate at 1.67 VPC, 25°C. Power data is as follows: 66.1 W/cell at the 5-minute rate, 1.67 VPC, 25°C; 32.0 W/cell at the 15-minute rate, 1.67 VPC, 25°C. The maximum charge current is 3.20 A, the maximum discharge current is 130 A, the short-circuit current is 335 A, and the internal resistance is 22.7 mΩ. Regarding charging and temperature conditions, the float charge voltage at 25°C is 13.5 to 13.8 Vdc/battery, and the equalization charge voltage is 14.4 to 15.0 Vdc/battery. The nominal operating temperature is 25°C; the discharge range is -15°C to 50°C; the charge and storage range is -15°C to 40°C. Self-discharge characteristics: stored at 25°C for 90 days, self-discharge is less than 10%, and storage is possible for up to 6 months, with a full charge required before use; if the storage temperature exceeds 25°C, charge in advance. In terms of dimensions and construction, the HR1232W is 150.9±2.0 mm long, 64.8±1.0 mm wide, and 98.6±1.0 mm high, weighs 2.34 kg, and has an F2-Faston Tab250 terminal type. The case is made of ABS material meeting UL 94-HB standards, and a flame-retardant 94-V0 version is also available upon request. Under float charge at 25°C, the design life is up to 5 years; according to the Eurobat 20°C standard, the commercial life is 3 to 5 years. This product is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 recognized under recognition number MH14533. With its high-rate discharge characteristics and float backup design, the HR1232W is suitable for data center UPS and other applications requiring rapid discharge backup, and can be used in long-term float charge at 25°C according to the float charge voltage above.
