Product details
The CSB EVX12750 belongs to the EVX series and is a 12V Top Terminal valve-regulated sealed lead-acid battery featuring AGM technology and a pure lead construction, officially positioned as a durable deep-cycle battery for e-mobility and cycling applications. Its nominal capacity is 75Ah (1.75 VPC @25°C, 20hr-rate), 64.56Ah at the 8-hour rate at 1.75 VPC @25°C, and 63.84Ah at the 8-hour rate at 1.80 VPC @25°C.
In terms of electrical parameters, the battery has a maximum charge current of 22.50A, a maximum discharge current of 500A, a short-circuit current of 1661A, and an internal resistance of 4.7mΩ. The equalizing charge voltage is 14.4 to 15.0 Vdc/battery (25°C). No float charge voltage value is provided in the documentation. For self-discharge, capacity loss is less than 10% after 90 days of storage 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, it should be charged sooner.
Structurally, the EVX12750 uses a PP case (UL 94-HB), with B6 terminal to accept M6 bolt, and a terminal torque of 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 277.0±2.5 mm in length, 168.5±2.0 mm in width, and 232.5±2.5 mm in height.
For operating temperature, the nominal temperature is 25°C (77°F), the discharge temperature range is -15°C to 50°C (5°F to 122°F), and the charge and storage temperature range is -15°C to 40°C (5°F to 104°F). The design life is 400 cycles at 100%DOD or 1800 cycles at 30%DOD at 25°C.
The battery is a valve-regulated lead-acid (VRLA) design, maintenance-free, using AGM technology to achieve up to 99% gas recombination efficiency, and is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008, and is UL1989 Recognized (MH14533). These features make it suitable for e-mobility and deep-cycle applications.
