Product details
As a member of the HR series, the CSB HR1227W is a 12V valve regulated sealed lead acid battery with top terminals. Utilizing Absorbent Glass Mat (AGM) technology, it achieves a gas recombination efficiency of up to 99%. Combined with its pure lead construction and proprietary formula, it is specifically designed for high rate discharge and float backup power applications. This model is officially classified under the high rate discharge pure lead battery series, primarily targeting UPS systems with lower power output and backup scenarios requiring rapid discharge. The officially designated application is data center uninterruptible power supplies.
Looking at the electrical specifications: the HR1227W has a voltage of 12 Vdc and a nominal capacity of 27W at the 15-minute rate at 1.67 VPC, 25°C. Its 5-minute rate power is 53.0 W/cell, and its 15-minute rate power is 27.0 W/cell, both also based on 1.67 VPC, 25°C. The maximum charge current is 2.70 A, the maximum discharge current is 130, the short circuit current is 424 A, and the internal resistance is 19.9 mΩ. The float charge voltage at 25°C is 13.5 to 13.8 Vdc/battery, and the equalization charge voltage at 25°C is 14.4 to 15.0 Vdc/battery.
In terms of construction and dimensions, the battery terminal is F2-Faston Tab250 type, and the case is made of ABS (UL 94-HB) material, with a flame-retardant 94-V0 version available upon request. The weight is 1.97 kg (4.34 lb), with a length of 90.0±1.0 mm, a width of 70.0±1.0 mm, and a height of 106.1±1.5 mm. The design life at 25°C float charge is 5 years, and the commercial life according to Eurobat (20°C) is 3 to 5 years.
Regarding operating temperature, the nominal temperature is 25°C (77°F), the discharge range is -15°C to 50°C (5°F to 122°F), and the charge and storage range is -15°C to 40°C (5°F to 104°F). For self-discharge, it is less than 10% after 90 days at 25°C, and it can be stored for up to 6 months at 25°C, but must be fully charged before use; if the storage temperature exceeds 25°C, a refresh charge is required.
This battery features a maintenance-free design, is manufactured according to IEC 61056-1/2:2012, and is recognized under UL1989 (MH14533). With its high rate discharge capability and stable float performance, the HR1227W is suitable for data center UPS and other applications requiring rapid discharge and backup power, maintaining reliable operation under specified float voltage and temperature conditions.
