Product details
The CSB TPL12400T belongs to the TPL series and is a 12V front terminal VRLA battery using absorbed glass mat (AGM) technology, with a gas recombination efficiency of up to 99%, in a maintenance-free construction. This series is positioned as a front terminal, long life telecom pure lead battery series, designed for multi-hour backup scenarios in broadband applications, with official application area being telecommunications.
In terms of capacity, the TPL12400T has a nominal capacity of 40Ah at 25°C, 1.80VPC, 10-hour rate; at 25°C, 1.75VPC, the 8-hour rate is 40.64Ah and the 20-hour rate is 45.20Ah; at 25°C, 1.80VPC, the 8-hour rate is 40.08Ah. The battery's maximum charge current is 12.0A, maximum discharge current is 400A, short-circuit current is 1256A, and internal resistance is 6.70 mΩ.
Regarding charging and temperature conditions, at 25°C the float charge voltage is 13.5 to 13.8 Vdc/battery, and the equalizing charge voltage is 14.4 to 15.0 Vdc/battery. The nominal operating temperature is 25°C, the discharge range is -15°C to 50°C, and the charge and storage range is -15°C to 40°C. Self-discharge is less than 10% after 90 days at 25°C, and the battery can be stored for up to 6 months at 25°C, requiring a full charge before use; if the storage temperature is above 25°C, charge earlier.
In construction, the TPL12400T uses a flame-retardant ABS case meeting UL 94-V0; the terminal is an I2 threaded lead alloy terminal accepting an M6 bolt, 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 is 15.0 kg.
The battery is designed for float standby power, with a design life of up to 12 years in standby service at 25°C, and greater than 12 years under Eurobat 20°C conditions, belonging to the very long life class. The product is manufactured according to IEC 60896-21/22:2004 and recognized under UL1989 (MH14533). The front terminal layout facilitates wiring and maintenance within cabinets, suitable for float standby applications such as telecommunications requiring long backup time.
