Product details
CSB XHRL12620W is a 12V valve-regulated sealed lead-acid battery with top terminals and belongs to the XHRL series. The XHRL series was developed from the HRL series, with enhanced high-rate output capability, and is mainly intended for float standby requirements such as data center UPS. Its separator uses absorbent glass mat (AGM), with gas recombination efficiency of up to 99%, and it is maintenance-free; the plate construction uses pure lead and a proprietary elemental formulation.
In terms of power and capacity, based on the 15-minute rate, single battery 10.02V, and 25°C conditions, this model has a nominal capacity of 620W. Under 25°C, 1.67VPC test conditions, each cell delivers 923.67 W/cell at the 5-minute rate and 620.00 W/cell at the 15-minute rate. Current and internal resistance limits: maximum charge current 62.00 A; maximum discharge current 800 (5 seconds); short-circuit current 3722 A; internal resistance 2.40 mΩ.
Dimensions: length 343.0±2.5 mm, width 170.0±2.0 mm, height 275.7±2.5 mm, weight 47.20 kg. Terminals use I2 threaded lead alloy and are suitable for M6 bolts; torque value 51.7±10.3 Kgf∙cm (44.9±9.0 Lbf∙in, 5.1±1.0 N∙m). The case uses PP material (UL 94-HB); if a flame-retardant 94-V0 specification is required, it can be supplied on request.
For charging parameters, at 25°C the float charge voltage range is 13.5–13.8 Vdc/battery, and the equalization charge voltage range is 14.4–15.0 Vdc/battery. Normal operating temperature is nominally 25°C; allowable discharge temperature is -15°C to 50°C; allowable charge and storage temperature is -15°C to 40°C. When stored at 25°C for 90 days, self-discharge is less than 10%; the normal storage period can reach 6 months, and if supplemented by equalization charging, it can be extended to 10 months. A full charge should be performed before putting into service; when storage temperature exceeds 25°C, supplementary charging is required in advance.
In terms of life and compliance, under 25°C float standby scenarios, the design service life is up to 10 years; according to the Eurobat standard at 20°C, the life exceeds 12 years. The manufacturing standard is IEC 60896-21/22:2004, and it is also UL1989 recognized (MH14533). With the above characteristics, this battery can be selected for standby power applications such as data center UPS that require high-rate output and float standby.
