Product details
The CSB XHRL12620W is a 12V top terminal valve-regulated sealed lead-acid battery belonging to the XHRL series. This series builds on the HRL to enhance high-rate output capability, targeting float standby applications such as data center uninterruptible power supplies. The battery uses absorbed glass mat, or AGM, technology, with gas recombination efficiency of up to 99%, is maintenance-free by design, and uses a pure lead construction with a proprietary element formula.
In terms of capacity and power, the XHRL12620W has a nominal capacity of 620W, corresponding to the 15-minute rate, 10.02V per cell, at 25°C. Its per-cell power at 25°C and 1.67VPC is 923.67 W/cell at the 5-minute rate and 620.00 W/cell at the 15-minute rate. The battery's maximum charge current is 62.00 A, maximum discharge current is 800 (5 seconds), short-circuit current is 3722 A, and internal resistance is 2.40 mΩ.
In terms of structure and dimensions, the battery is 343.0±2.5 mm long, 170.0±2.0 mm wide, and 275.7±2.5 mm high, and weighs 47.20 kg. The terminal is an I2 threaded lead alloy terminal that accepts an M6 bolt, with a terminal torque of 51.7±10.3 Kgf∙cm, i.e. 44.9±9.0 Lbf∙in or 5.1±1.0 N∙m. The case material is PP (UL 94-HB), and a flame-retardant 94-V0 version is available on request.
In terms of charging and temperature conditions, at 25°C the float charge voltage is 13.5 to 13.8 Vdc/battery, and the equalizing charge voltage is 14.4 to 15.0 Vdc/battery. The nominal operating temperature is 25°C, the discharge temperature range is -15°C to 50°C, and the charge and storage temperature range is -15°C to 40°C. In terms of self-discharge, at 25°C it is less than 10% after 90 days, and it can be stored for up to 6 months, or up to 10 months with equalizing charge; it must be fully charged before use, and if the storage temperature is above 25°C it should be charged sooner.
In terms of life, the battery has a design life of up to 10 years in 25°C float standby service, and over 12 years of long life under Eurobat 20°C conditions. The product is manufactured in accordance with IEC 60896-21/22:2004 and is UL1989 recognized (MH14533). These characteristics make it suitable for backup power applications such as data center UPS that require high-rate output and float standby.
