Product details
The official application area of the EVX12340 is electric mobility; it belongs to the CSB EVX series, which is positioned as a durable deep cycle battery and can serve electric mobility and cyclic energy storage applications. As a 12V valve-regulated sealed lead-acid battery, the EVX12340 uses AGM technology and pure lead construction, with gas recombination efficiency up to 99%.
In terms of capacity, at 25°C, 1.75VPC, and 20-hour rate, the EVX12340 has a nominal capacity of 34Ah. At 25°C, the 8-hour rate 1.75VPC capacity is 27.68Ah, the 20-hour rate 1.75VPC capacity is 34.40Ah, and the 8-hour rate 1.80VPC capacity is 27.28Ah. For charge and discharge capability, maximum charge current is 10.20A, maximum discharge current is 400A, short-circuit current is 849A, and internal resistance is 9.2mΩ; at 25°C, equalization voltage is 14.4 to 15.0Vdc/battery.
Battery dimensions are length 195.6±2.0mm, width 130.0±1.5mm, height 178.3±2.0mm, and weight 10.77kg (23.74 lb.). Its B5 type terminal accepts M6 nuts and bolts, and terminal torque is 51.7±10.3Kgf·cm, 44.9±9.0Lbf·in, or 5.1±1.0N·m. The case uses ABS, with flame retardant rating UL 94-HB.
Operating temperature range: nominal temperature 25°C (77°F), discharge temperature -15°C to 50°C (5°F to 122°F), charge and storage temperature -15°C to 40°C (5°F to 104°F). At 25°C, 100%DOD cycle design life is 400 cycles, and 30%DOD cycle design life is 1800 cycles. For self-discharge, after 90 days of storage at 25°C, remaining capacity exceeds 90%, and maximum storage is 6 months; fully charge before reuse, and when storage temperature is above 25°C, charge earlier.
This battery is maintenance-free, with gas recombination efficiency up to 99%, and is manufactured in accordance with IEC 60254-1:2005, IEC 60254-2:2008, and UL1989 Recognized (MH14533).
