Product details
The HRL12540W battery is a member of the CSB HRL series 6V + 12V Top Terminal VRLA-AGM family. Its rated voltage is 12 Vdc, and its nominal capacity is expressed as 540W @15min-rate (1.67 VPC @25°C). At 1.67 VPC @ 25°C, the 5-Min power is 838 W/cell, while the 15-Min power is 542 W/cell. The HRL series is officially defined as a long life, high rate UPS pure lead battery series, mainly serving high power data centers and UPS loads. The officially designated application is Datacenter UPS, which means data center uninterruptible power supply.
In terms of electrical performance, the HRL12540W can withstand a maximum charging current of 54 A, a maximum discharge current of 800 A, a short-circuit current of 3523 A, and an internal resistance of 2.60 mΩ. The float charging voltage range is 13.5 - 13.8 Vdc/battery 25°C, and the equalization charging voltage range is 14.4 - 15.0 Vdc/battery 25°C. The nominal operating temperature is 25°C, with discharge allowed from -15°C - 50°C, and charging and storage allowed from -15°C - 40°C. In terms of self-discharge characteristics, storage at 25°C for 90 days results in less than 10% capacity loss, and it can be stored for up to 6 months, but it must be fully charged before use. If the storage temperature exceeds 25°C, it should be charged earlier.
Structurally, the battery uses a valve-regulated lead-acid (VRLA) design, belongs to maintenance-free absorbed glass mat (AGM) technology, can achieve a gas recombination efficiency of 99%, and uses pure lead construction with proprietary elements. The terminal specification is I2 thread lead alloy terminal to accept M6 bolt, with recommended torque of 51.7±10.3 Kgf·cm, 44.9±9.0 Lbf·in, 5.10±1.0 N·m. The case is made of PP (UL 94-HB), and a flame-retardant (94-V0) version can also be provided on request. In terms of dimensions, the length is 343.0±2.5 mm, width 170.0±2.0 mm, height 275.7±2.5 mm, and weight 43.90 kg (96.76 lb.).
In terms of design life, it can reach 10 years in 25°C float standby service, and more than 12 years under Eurobat (20°C) conditions, and is classified as Very Long Life. The product is manufactured according to IEC 60896-21/22:2004 and has obtained UL1989 Recognized (MH14533). These features enable the HRL12540W to handle applications such as data center uninterruptible power supply that require high-rate discharge and float standby. During installation and maintenance, the voltage, temperature, and torque conditions given in the data must be followed.
