Product details

The CSB TPL121250AFR is a 12V front terminal valve-regulated sealed lead-acid battery belonging to the TPL series. Technically, it uses absorbent glass mat (AGM) separators, with a maximum gas recombination efficiency of up to 99%, and pure lead plates with proprietary additives. The series is positioned as long-life telecom pure lead batteries, featuring a front terminal design, primarily targeting broadband applications requiring multi-hour backup durations. In terms of capacity data, at 25°C, the 10-hour rate nominal capacity at 1.80VPC is 125Ah; the 8-hour rate at 1.75VPC is 125Ah, the 20-hour rate at 1.75VPC is 135Ah, and the 8-hour rate at 1.80VPC is 121Ah. Electrically, the maximum charge current is up to 37.5A, the maximum discharge current is 800A, the short-circuit current is 2327A, and the internal resistance is 4.50mΩ. Dimensions are 547.0mm in length, 124.8mm in width, and 320.3mm in height, with a weight of approximately 44.70kg. The terminal type is I2 threaded lead alloy, accepting M6 bolts, with a recommended torque of 5.1±1.0 N·m. The case is made of flame-retardant ABS material, compliant with UL 94-V0. Under 25°C float charge conditions, the design life can reach 12 years, meeting the Eurobat long life standard. The float charge voltage range is 13.5 to 13.8Vdc, and the equalization charge voltage is 14.4 to 15.0Vdc. For 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. For self-discharge, it is less than 10% after 90 days, can be stored for up to 6 months at 25°C, requires a full charge before use, and if storage temperature exceeds 25°C, charging is required earlier. This battery is maintenance-free, suitable for float standby power applications, manufactured according to IEC 60896-21/22:2004, and recognized under UL1989 (MH14533). The front terminal structure facilitates cabinet installation and maintenance, suitable for telecom and communication float applications requiring long life and multi-hour backup.
