Product details
The CSB HRL1234W belongs to the HRL series, with a nominal voltage of 12 Vdc, a 6V and 12V top terminal structure, and is a valve regulated sealed lead acid battery. This series is positioned around long life and high rate pure lead, mainly serving data centers and uninterruptible power supply scenarios with larger load demands, with the official application area being data center uninterruptible power supplies.
In terms of capacity and power, at 25°C and 1.67 VPC, the battery has a nominal capacity of 34W @15min-rate. Also at 25°C and 1.67 VPC, the per-cell power performance is: 75.34 W/cell at the 5-minute rate and 35.50 W/cell at the 15-minute rate. The maximum charge current is 3.40 A, the maximum discharge current is 130 A, the short circuit current is 367 A, and the internal resistance is 17.0 mΩ.
In terms of construction, the HRL1234W uses valve regulated sealed lead acid design and Absorbent Glass Mat technology, with a gas recombination efficiency of up to 99%, and is maintenance-free; it also uses pure lead construction and a proprietary element formula. The case is ABS (UL 94-HB), and a flame retardant 94-V0 version can also be provided on request. The terminal type is F2 terminal - Faston Tab 250. It is manufactured in accordance with IEC 61056-1/2:2012 and is UL1989 Recognized (MH14533).
Dimensions and weight: length 150.9±2.0 mm, width 64.8±1.0 mm, height 98.6±1.0 mm, weight 2.70 kg. The design life is up to 8 years in 25°C float backup service; the Eurobat (20°C) standard commercial life is 10 to 12 years. The nominal operating temperature is 25°C, the discharge range is minus 15°C to 50°C, and the charge and storage range is minus 15°C to 40°C.
Charge parameters: at 25°C, the float charge voltage is 13.5 to 13.8 Vdc/battery, and the equalization charge voltage is 14.4 to 15.0 Vdc/battery.
