Product details
The CSB EVX12340 in the EVX series is a 12V valve-regulated sealed lead-acid battery that utilizes AGM technology, achieves up to 99% gas recombination efficiency, and features a pure lead construction. This series is positioned for electric mobility and cyclic energy storage applications, emphasizing durable deep cycle characteristics, with the EVX12340 officially intended for electric mobility.
In terms of capacity, the nominal capacity is 34Ah measured at 25°C at 1.75VPC and the 20-hour rate; also at 25°C, the 8-hour rate capacity at 1.75VPC is 27.68Ah, the 20-hour rate capacity at 1.75VPC is 34.40Ah, and the 8-hour rate capacity at 1.80VPC is 27.28Ah. The maximum charging current is 10.20A, the maximum discharging current is 400A, the short-circuit current is 849A, and the internal resistance is 9.2mΩ. At 25°C, the equalization voltage ranges from 14.4 to 15.0Vdc/battery.
In terms of dimensions, the length is 195.6±2.0mm, width 130.0±1.5mm, height 178.3±2.0mm, and weight 10.77kg (23.74 lb.). The B5 type terminal can be used with M6 nuts and bolts, with a torque of 51.7±10.3Kgf·cm, 44.9±9.0Lbf·in, or 5.1±1.0N·m. The housing is made of ABS material and achieves a flame retardant rating of UL 94-HB.
Temperature conditions: nominal 25°C (77°F); discharge allowed from -15°C to 50°C (5°F to 122°F); charging and storage allowed from -15°C to 40°C (5°F to 104°F). The design life is 400 cycles at 100%DOD at 25°C, or 1800 cycles at 30%DOD. Self-discharge performance: after 90 days of storage at 25°C, the remaining capacity is still above 90%, with a maximum storage of 6 months, and a full charge is required before use; if the storage temperature exceeds 25°C, charging is required earlier.
This battery is maintenance-free, with a maximum gas recombination efficiency of 99%, and production complies with IEC 60254-1:2005, IEC 60254-2:2008, and UL1989 Recognized (MH14533). Its deep cycle capability aligns with its electric mobility positioning, making it suitable for scenarios requiring repeated charge and discharge.
