Product details
The HRL series covers 6V and 12V top-terminal VRLA batteries, and the CSB HRL12390W is one of them. Officially positioned as a long-life, high-rate pure lead battery, this model is primarily intended for high-power data center and UPS loads. Its rated voltage is 12 Vdc; at 25°C and 1.67 VPC, the 15-minute rate nominal capacity reaches 390W, the 5-minute rate power is 700 W/cell, and the 15-minute rate power is 414 W/cell, making it well suited for float standby scenarios requiring short-duration high-power output.
In terms of construction, the battery combines VRLA design with absorbed glass mat technology, achieving gas recombination efficiency of up to 99%, and is maintenance-free. Both positive and negative plates use pure lead construction and a proprietary formula; the official application area listed is data center uninterruptible power supplies. The case material is PP (UL 94-HB), and a flame-retardant (94-V0) version is also available upon request.
For electrical specifications, the HRL12390W has a maximum charge current of 39.0 A, maximum discharge current of 800 A, short-circuit current of 2779 A, and internal resistance of 3.00 mΩ. At 25°C, the float charge voltage ranges from 13.5 to 13.8 Vdc/battery, and the equalize charge voltage is 14.4 to 15.0 Vdc/battery. The terminals use the I2 threaded lead alloy type, compatible with M6 bolts, with a torque value 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, weighing 33.00 kg (72.73 lb). The nominal operating temperature is 25°C; discharge is permitted from -15°C to 50°C, while charging and storage are permitted from -15°C to 40°C. Design life can reach 10 years under float charge at 25°C; according to the Eurobat long life standard, it can exceed 12 years at 20°C.
In terms of self-discharge performance, after 90 days of storage at 25°C, the remaining capacity is still above 90%, and storage can last up to 6 months, with a full charge required before use; if the storage temperature exceeds 25°C, earlier charging is required. This product is manufactured in accordance with IEC 60896-21/22:2004 and is UL1989 recognized (MH14533).
