Product details

The CSB TPL12400T is a TPL series product, a 12V front terminal VRLA battery. It utilizes AGM (Absorbent Glass Mat) technology, achieving a gas recombination efficiency of up to 99%, and features a maintenance-free design. This series is positioned as a front terminal, long life telecom pure lead battery series, developed for multi-hour backup time requirements in broadband applications, with the official application direction being telecom. In terms of capacity performance, the TPL12400T has a nominal capacity of 40Ah at 25°C, 1.80VPC, 10-hour rate; also at 25°C, at 1.75VPC the 8-hour rate is 40.64Ah and the 20-hour rate is 45.20Ah; if the conditions are 25°C, 1.80VPC, the 8-hour rate is 40.08Ah. The battery has a maximum charge current of 12.0A, maximum discharge current of 400A, short circuit current of 1256A, and internal resistance of 6.70 mΩ. Regarding temperature and charging parameters, at 25°C the float charge voltage range is 13.5 to 13.8 Vdc/battery, and the equalize charge voltage is 14.4 to 15.0 Vdc/battery. The nominal operating 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. At 25°C, self-discharge is less than 10% after 90 days, and it can be stored for up to 6 months at 25°C, but must be fully charged before use; if the storage temperature exceeds 25°C, charging is required earlier. In terms of construction, the TPL12400T case uses flame-retardant ABS material, meeting UL 94-V0 standard; the terminal is an I2 threaded lead alloy type, compatible with M6 bolts, with terminal torque of 51.7±10.3 Kgf∙cm, 44.9±9.0 Lbf∙in, 5.1±1.0 N∙m. Dimensions are length 280.0±2.5 mm, width 105.0±1.5 mm, height 195.0±2.0 mm, and weight 15.0 kg. This battery is designed for float charge backup power, with a design life of up to 12 years in 25°C standby service, and more than 12 years under Eurobat 20°C conditions, belonging to the very long life category. The product is manufactured according to IEC 60896-21/22:2004 and is UL1989 recognized (MH14533). The front terminal layout makes wiring and maintenance in cabinets more convenient, suitable for float charge backup applications such as telecom that require long backup time.
