Product details
As a member of the HRL series (covering 6V and 12V top terminal VRLA batteries), the CSB HRL12390W is officially defined as a long life high rate pure lead battery, primarily serving high power data centers and UPS loads. The battery has a nominal voltage of 12 Vdc; under test conditions of 25°C and 1.67 VPC, the 15-minute rate rated capacity reaches 390W, while the 5-minute rate power is 700 W/cell and the 15-minute rate power is 414 W/cell, making it suitable for float backup scenarios requiring short-term high power.
With VRLA design and Absorbent Glass Mat (AGM) technology, the battery achieves a gas recombination efficiency of up to 99% and is maintenance-free. Both positive and negative plates use pure lead construction and a proprietary formula, and the officially designated application is data center uninterruptible power supply. The case is made of PP material (UL 94-HB compliant), and a flame-retardant (94-V0) version is available upon request.
In terms of electrical characteristics, the HRL12390W can withstand a maximum charge current of 39.0 A, a maximum discharge current of 800 A, a short-circuit current of 2779 A, and an internal resistance of only 3.00 mΩ. At 25°C, the float charge voltage range is 13.5 to 13.8 Vdc/battery, and the equalize charge voltage is 14.4 to 15.0 Vdc/battery. Its I2 threaded lead alloy terminal accommodates M6 bolts, with torque specifications of 51.7±10.3 Kgf·cm, 44.9±9.0 Lbf·in, or 5.10±1.0 N·m.
In terms of dimensions and weight, the battery is 343.0±2.5 mm long, 170.0±2.0 mm wide, and 216.9±2.5 mm high, with an overall weight of 33.00 kg (72.73 lb). The nominal operating temperature is 25°C; the allowable discharge range is between -15°C and 50°C, while the charge and storage temperature range is between -15°C and 40°C. Under float charge at 25°C, the design life can be up to 10 years; if it meets the Eurobat long life standard, it can exceed 12 years at 20°C.
Self-discharge performance: after 90 days of storage at 25°C, the remaining capacity is still above 90%, and it can be stored for up to 6 months, but must be fully charged before use; if the storage temperature exceeds 25°C, charging should be performed earlier. This product is manufactured according to IEC 60896-21/22:2004 and has obtained UL1989 certification (MH14533).
