Product details

As a member of the TPL series, the CSB TPL121250AFR is a 12V front terminal valve-regulated sealed lead-acid battery. The product uses absorbed glass mat separator technology, with gas recombination efficiency of up to 99%, and incorporates pure lead construction and proprietary elements. In broadband applications, the series can handle scenarios requiring multiple hours of backup time and is positioned as a front terminal long-life telecom pure lead battery series. Dimensions and terminals: length 547.0mm, width 124.8mm, height 320.3mm, weight approximately 44.70kg; I2 threaded lead alloy terminals accept M6 bolts, recommended torque 5.1±1.0 N·m; the case is made of flame-retardant ABS and meets the UL 94-V0 standard. Capacity and current: at 25°C and 1.80VPC, the 10-hour rate nominal capacity is 125Ah; at 1.75VPC, the 8-hour rate capacity is 125Ah and the 20-hour rate capacity is 135Ah; at 1.80VPC, the 8-hour rate capacity is 121Ah. Maximum charge current 37.5A, maximum discharge current 800A, short-circuit current 2327A, internal resistance 4.50mΩ. Charging, temperature, and storage: when used in float charge at 25°C, the design life can reach 12 years and meets the Eurobat long-life standard; float voltage 13.5 to 13.8Vdc, equalization voltage 14.4 to 15.0Vdc. Nominal temperature 25°C, discharge temperature range -15°C to 50°C, charging and storage temperature range -15°C to 40°C. Self-discharge rate is less than 10% after 90 days; it can be stored for up to 6 months at 25°C and must be fully charged before use; if storage temperature is above 25°C, recharge sooner. The battery is maintenance-free and can be used for float standby power. It is manufactured to IEC 60896-21/22:2004 and is recognized under UL1989 (MH14533). The front terminal design makes cabinet installation and maintenance more convenient, making it suitable for float-charge requirements in telecommunications and other applications requiring long life and multi-hour backup.
