Product details
The CSB EVX12750 is a 12V Top Terminal valve-regulated sealed lead-acid battery in the EVX series. Built with AGM technology and a pure lead construction, it is officially positioned as a durable deep cycle battery suitable for electric mobility and cyclic charge/discharge applications.
The battery has a nominal capacity of 75Ah (1.75 VPC @25°C, 20hr-rate); when discharged at the 8-hour rate, 1.75 VPC @25°C, the capacity is 64.56Ah; at the 8-hour rate, 1.80 VPC @25°C, it is 63.84Ah.
In terms of electrical performance, the maximum charge current can reach 22.50A, the maximum discharge current is 500A, the short-circuit current is 1661A, and the internal resistance is only 4.7mΩ. The equalization voltage at 25°C is 14.4 to 15.0 Vdc/battery. Regarding float voltage, no value is given in the data. As for self-discharge characteristics, storage at 25°C for 90 days results in less than 10% capacity loss; storage at 25°C is possible for up to 6 months, but a full charge is required before use; if the storage temperature exceeds 25°C, charging is required earlier.
In terms of construction, the EVX12750 case material is PP (UL 94-HB), the terminals are B6 terminal to accept M6 bolt, and the terminal torque is 51.7±10.3 Kgf·cm, 44.9±9.0 Lbf·in, or 5.10±1.0 N·m. The battery weighs 25.60 kg (56.38 lb), with dimensions of length 277.0±2.5 mm, width 168.5±2.0 mm, and height 232.5±2.5 mm.
Operating temperature range: nominal temperature 25°C (77°F); discharge temperature from -15°C to 50°C (5°F to 122°F); charge and storage temperature from -15°C to 40°C (5°F to 104°F). In terms of design life, at 25°C, 100%DOD cycling can reach 400 cycles, or 30%DOD cycling can reach 1800 cycles.
This battery uses a valve-regulated sealed lead-acid (VRLA) design, is maintenance-free, and achieves up to 99% gas recombination efficiency through AGM technology. It is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008, and is also UL1989 Recognized (MH14533). These features make it suitable for electric mobility and deep cycle applications.
