Product details
CSB XHRL12170W belongs to the XHRL product line and is a 12V valve-regulated sealed lead-acid battery with terminals located on top. As a high-performance version of HRL, this series is designed for UPS and data centers and can provide higher high-rate output. Inside, the battery uses an absorbed glass mat (AGM) separator and valve-regulated sealed construction, with gas recombination efficiency up to 99%; it also uses pure lead construction with a proprietary element formula, designed specifically for high-rate UPS and float standby power applications.
From a power performance perspective, under 15-minute rate conditions the XHRL12170W has a nominal capacity of 170W, tested at 25°C and 10.02V per battery. At 25°C and 1.67 VPC, its output per cell is: 321.33 W/cell at the 5-minute rate, and 173.67 W/cell at the 15-minute rate. Maximum charge current is 17.00 A, maximum discharge current is 400 (5 sec), short-circuit current is 1243 A, and internal resistance is 6.33 mΩ.
Regarding charging and temperature conditions, nominal operating temperature is 25°C. Discharge can range from -15°C to 50°C, while charging and storage can range from -15°C to 40°C. At 25°C, the float voltage range is 13.5 to 13.8 Vdc/battery, and the equalization voltage range is 14.4 to 15.0 Vdc/battery. Self-discharge performance: after 90 days at 25°C, self-discharge is less than 10%; it can be stored for 6 months, or extended to 10 months with equalization charging. A full charge is required before use; when storage temperature is above 25°C, charge earlier.
In terms of construction and dimensions, battery weight is 13.58 kg (29.94 lb), length 197.0±2.0 mm, width 165.0±2.0 mm, and height 170.4±2.0 mm. Terminals are I2 threaded lead-alloy terminals and can accept M6 bolts; torque is 51.7±10.3 Kgf∙cm, 44.9±9.0 Lbf∙in, or 5.1±1.0 N∙m. The case material is ABS (UL 94-HB); a flame-retardant 94-V0 version is available on request.
Regarding life and compliance, this battery is manufactured in accordance with IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533). For 25°C float standby use, design life can reach 10 years; under Eurobat (20°C) conditions, long life exceeds 12 years. Its maintenance-free characteristics and high-rate output make it suitable for float standby applications such as data center uninterruptible power supplies.
