Product details

Under test conditions of 25°C and 1.75 VPC, the XTV12550 has a 20-hour rate nominal capacity of 55Ah and an 8-hour rate capacity of 53.6Ah; when the condition is changed to 1.80 VPC, the 8-hour rate capacity is 52.3Ah. The battery comes from the CSB XTV series, is a 12V valve-regulated sealed lead-acid battery, uses pure lead combined with AGM technology, and is officially positioned as a VRLA pure lead product for telecom broadband applications; it can be deployed indoors or outdoors. Electrically, at 25°C, the float voltage range of the XTV12550 is 13.5 Vdc/battery to 13.8 Vdc/battery, and the equalization voltage range is 14.4 Vdc/battery to 15.0 Vdc/battery; the maximum charge current is 16.5A, the maximum discharge current is 300A, the short-circuit current is 1627A, and the internal resistance is 5.20 mΩ. In telecom float standby scenarios, charge and discharge management can be based on the above values. The battery is equipped with I2 threaded lead alloy terminals, can accept M6 bolts, and has 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. In terms of dimensions, it is 228.0±2.5mm long, 138.4±1.5mm wide, and 206.3±2.5mm high, with a weight of approximately 17.90kg. The case uses PP material (UL 94-HB); a flame-retardant (94-V0) version can also be provided upon customer request. In terms of environmental capabilities, 25°C is the nominal operating temperature; charging and discharging can occur from -20°C to 50°C, and the storage temperature range is -15°C to 40°C. Under float charging at 25°C, the XTV12550 has a design life of up to 12 years, meeting the Eurobat long life standard category of more than 12 years at 20°C. In terms of self-discharge, the loss is less than 10% after 90 days of storage at 25°C, and it can be stored for up to 6 months; it should be fully charged before reuse, and if the storage temperature exceeds 25°C, an earlier recharge is required. The XTV12550 features a maintenance-free design, with gas recombination efficiency in the AGM structure of up to 99%, and is developed for float standby power applications at extreme temperatures. Production follows IEC 60896-21/22:2004 and it is UL1989 recognized (MH14533). Therefore, it is suitable for telecom and other applications requiring long-duration float standby power.
