Product details

The CSB XTV12550, part of the XTV series, is a 12V valve regulated sealed lead acid battery. It utilizes AGM technology and a pure lead construction, officially defined as a VRLA pure lead series for telecom broadband applications, suitable for both indoor and outdoor environments. At 25°C and 1.75 VPC, the battery delivers a 20-hour rate nominal capacity of 55Ah and an 8-hour rate capacity of 53.6Ah; at 1.80 VPC, the 8-hour rate capacity is 52.3Ah. In terms of electrical parameters, the XTV12550 at 25°C has a float charge voltage range of 13.5 to 13.8 Vdc/battery, an equalize charge voltage range of 14.4 to 15.0 Vdc/battery, a maximum charge current of 16.5A, a maximum discharge current of 300A, a short-circuit current of 1627A, and an internal resistance of 5.20 mΩ. Charge and discharge management for telecom float standby applications can be based on these parameters. For terminals, the battery uses I2 threaded lead alloy, compatible with M6 bolts, with torque values of 51.7±10.3 Kgf∙cm, 44.9±9.0 Lbf∙in, or 5.1±1.0 N∙m. Dimensions are length 228.0±2.5mm, width 138.4±1.5mm, height 206.3±2.5mm, and weight approximately 17.90kg. The case material is PP (UL 94-HB), and a flame-retardant (94-V0) version is available upon request. Regarding environmental adaptability, the XTV12550 has a nominal operating temperature of 25°C, a discharge and charge temperature range of -20°C to 50°C, and a storage temperature range of -15°C to 40°C. When used under float charge at 25°C, the design life can reach 12 years, meeting the Eurobat long life standard classification of greater than 12 years at 20°C. Self-discharge performance: stored at 25°C for 90 days, self-discharge is less than 10%, and it can be stored for up to 6 months; it must be fully charged before use; if storage temperature exceeds 25°C, charge it earlier. This battery features a maintenance-free design, with AGM technology providing up to 99% gas recombination efficiency, specifically built for float standby power applications in extreme temperature environments. Production complies with IEC 60896-21/22:2004 and is UL1989 recognized (MH14533). Therefore, it is suitable for telecom and other applications requiring long-term float standby power.
