Product details

The CSB XTV12550 is a product in the XTV series and is a 12V valve-regulated sealed lead-acid battery that combines AGM technology with a pure lead construction. The manufacturer positions it 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 has a nominal 20-hour rate 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 specifications, the XTV12550 has a float charge voltage of 13.5 to 13.8 Vdc/battery at 25°C, an equalize charge voltage 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. These parameters provide a reference for charge and discharge management in telecom float standby applications. The battery is equipped with I2 threaded lead alloy terminals that accept M6 bolts, with a terminal torque of 51.7±10.3 Kgf∙cm, 44.9±9.0 Lbf∙in, or 5.1±1.0 N∙m. In terms of dimensions, it measures 228.0±2.5mm in length, 138.4±1.5mm in width, and 206.3±2.5mm in height, and weighs approximately 17.90kg. The case is made of PP (UL 94-HB) material, and a flame-retardant (94-V0) version can be provided on request. For 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. Under float charge conditions 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. The self-discharge rate is less than 10% after 90 days at 25°C, and the battery can be stored for up to 6 months; it must be fully charged before use, and if the storage temperature is above 25°C, it should be charged earlier. This battery features a maintenance-free design, and the gas recombination efficiency of the AGM technology can reach 99%. It is specifically built for float standby power applications in extreme temperature environments and is manufactured in accordance with IEC 60896-21/22:2004, with UL1989 recognition (MH14533). These features make it suitable for applications such as telecommunications that require long-term float standby power.
