Product details
In data center UPS and other float standby scenarios requiring short-duration high power, the CSB HRL12390W belongs to the HRL series; this series covers 6V and 12V top-terminal valve-regulated sealed lead-acid batteries, officially positioned as long-life, high-rate pure lead batteries for high-power data centers and UPS loads. This model has a rated voltage of 12 Vdc; at 25°C and 1.67 VPC, the 15-minute rate nominal capacity is 390W, the 5-minute rate power is 700 W/cell, and the 15-minute rate power is 414 W/cell; it can be used for float standby requiring short-duration high-power output.
In terms of dimensions, the HRL12390W is 216.9±2.5 mm high, 343.0±2.5 mm long, 170.0±2.0 mm wide, and weighs 33.00 kg (72.73 lb). Nominal operating temperature is 25°C; discharge temperature range is -15°C to 50°C, and charging and storage temperature range is -15°C to 40°C. When used in float charge at 25°C, design life can reach 10 years; when meeting the Eurobat long-life standard, it exceeds 12 years in a 20°C environment.
Electrically, maximum charge current is 39.0 A, maximum discharge current is 800 A, short-circuit current is 2779 A, and internal resistance is 3.00 mΩ. At 25°C, float voltage is maintained at 13.5 to 13.8 Vdc/battery, and equalization voltage is maintained at 14.4 to 15.0 Vdc/battery. The terminal type is an I2 threaded lead-alloy terminal and accepts M6 bolts; torque is 51.7±10.3 Kgf·cm, 44.9±9.0 Lbf·in, or 5.10±1.0 N·m.
Structurally, it uses a valve-regulated sealed lead-acid construction with absorbent glass mat technology, gas recombination efficiency up to 99%, and is maintenance-free; the positive and negative plates are made of pure lead with a proprietary formulation. The case material is PP (UL 94-HB); a flame-retardant (94-V0) version can be supplied upon request. The official application is data center uninterruptible power supplies.
In terms of self-discharge, after 90 days of storage at 25°C, remaining capacity is greater than 90%, and it can be stored for up to 6 months; it must be fully charged before use. If storage temperature is above 25°C, charge earlier. Manufacturing complies with IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533).
