Product details

CSB TPL121250AFR is a product in the TPL series, featuring a front terminal structure. It belongs to the VRLA battery type and utilizes Absorbent Glass Mat technology with a gas recombination efficiency of 99%, while incorporating pure lead construction and a proprietary element formula. This series is positioned as a long life telecom pure lead front terminal battery series, mainly serving broadband applications that require several hours of backup power. In terms of capacity, at 25°C, the 10-hour rate (1.80VPC) nominal capacity is 125Ah; at the 8-hour rate (1.75VPC) it is also 125Ah; at the 20-hour rate (1.75VPC) it reaches 135Ah; at the 8-hour rate (1.80VPC) it is 121Ah. The maximum charge current is 37.5A, the maximum discharge current is 800A, the short circuit current is 2327A, and the measured internal resistance is 4.50mΩ. Regarding dimensions and terminals, the battery is 547.0mm long, 124.8mm wide, and 320.3mm high, weighing approximately 44.70kg. The terminal is an I2 threaded lead alloy type, compatible with M6 bolts, with a recommended torque of 5.1±1.0 N·m. Flame retardant ABS is used as the case material, meeting UL 94-V0 standard. Under float charge at 25°C, the design life can be up to 12 years, meeting Eurobat long life requirements. The float charge voltage range is 13.5 to 13.8Vdc, and the equalize charge voltage is between 14.4 and 15.0Vdc. In terms of temperature adaptability, the nominal temperature is 25°C, discharge can be performed from -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 for up to 6 months at 25°C; fully charge before use. When the storage temperature exceeds 25°C, charge in advance. This battery features a maintenance-free design, suitable for float charge backup power scenarios. It is manufactured according to IEC 60896-21/22:2004 standards and is UL1989 recognized (MH14533). The front terminal structure makes cabinet installation and maintenance more convenient, meeting the float charge application needs for long life and multi-hour backup power in telecom and other fields.
