Product details

The CSB TPL121250AFR belongs to the TPL series and is a 12V front terminal valve-regulated lead-acid battery using absorbed glass mat technology, with a gas recombination efficiency of up to 99%, and employing pure lead construction and proprietary elements. This series is positioned as a front terminal long life telecom pure lead battery series, aimed at broadband applications requiring multi-hour backup duration. In terms of capacity, the battery has a nominal capacity of 125Ah at the 10-hour rate at 25°C and 1.80VPC; 125Ah at the 8-hour rate at 1.75VPC, 135Ah at the 20-hour rate at 1.75VPC, and 121Ah at the 8-hour rate at 1.80VPC. The maximum charge current is 37.5A, the maximum discharge current is 800A, the short-circuit current is 2327A, and the internal resistance is 4.50mΩ. The battery dimensions are 547.0mm long, 124.8mm wide, and 320.3mm high, with a weight of approximately 44.70kg. The terminals use I2 threaded lead alloy terminals, accept M6 bolts, and the recommended torque is 5.1±1.0 N·m. The case material is flame-retardant ABS, compliant with UL 94-V0. Under float service conditions at 25°C, the design life can reach 12 years, meeting the Eurobat long life standard. The float charge voltage is 13.5 to 13.8Vdc, and the equalizing charge voltage is 14.4 to 15.0Vdc. Regarding operating temperature, the nominal 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. The self-discharge rate is less than 10% after 90 days, and it can be stored at 25°C 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. The battery is maintenance-free, suitable for float standby power applications, manufactured in accordance with IEC 60896-21/22:2004, and recognized under UL1989 (MH14533). Its front terminal structure facilitates cabinet installation and maintenance, making it suitable for float applications such as telecommunications that require long life and multi-hour backup.
