Product details
The CSB XHRL12500W is a 12V top-terminal valve-regulated sealed lead-acid battery in the XHRL series. It uses absorbed glass mat (AGM) technology with a gas recombination efficiency of up to 99% and is maintenance-free throughout. Compared with the HRL series, the XHRL series provides stronger high-rate output, and its factory-specified application is data center uninterruptible power supplies, making it suitable for float standby power environments.
In terms of power, the XHRL12500W delivers a nominal capacity of 500W at the 15-minute rate at 25°C and 10.02V per cell. With 1.67 VPC as the end voltage, the 5-minute rate power reaches 912.17 W/cell, and the 15-minute rate power is 502.83 W/cell. Its maximum charge current is 50.00 A, maximum discharge current is 1200 (5 seconds), short-circuit current is 3685 A, and internal resistance is 2.22 mΩ. These figures show that the battery is designed for short-duration, high-rate discharge.
In dimensions and weight, it measures 343.0±2.5 mm long, 170.0±2.0 mm wide, and 216.6±2.5 mm high, and weighs approximately 36.90 kg. The terminal is an I2 threaded lead alloy type compatible with M6 bolts, with a terminal torque of 51.7±10.3 Kgf∙cm, equivalent to 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 also available on request.
Charging and temperature conditions: at 25°C, the float charge voltage is 13.5 to 13.8 Vdc/battery, and the equalize 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. For self-discharge, storage at 25°C for 90 days is below 10%, and the battery can be stored for 6 months, extendable to 10 months with equalize charging; it must be fully charged before use, and if storage temperature exceeds 25°C, recharge should be done earlier.
For design life, it reaches 10 years in float standby service at 25°C and exceeds 12 years under Eurobat 20°C conditions, placing it in the Very Long Life category. The product is manufactured in accordance with IEC 60896-21/22:2004 and is UL1989 recognized (MH14533). Thanks to its pure lead construction and proprietary formulation, the XHRL12500W is well suited to applications such as data center UPS that require high-rate output and long-term float standby.
