Product details

CSB's EVH12140 belongs to the EVH series; by type it is a 12V Top Terminal VRLA-AGM battery, and the manufacturer's official application direction for it is electric mobility. This series is positioned as an advanced version for electric mobility; compared with the EVX series, both cycle life and cycle endurance are enhanced, so it can be used in electric mobility or deep-cycle applications. Structurally, it uses a valve-regulated sealed lead-acid design and absorbed glass mat (AGM) technology, with gas recombination efficiency up to 99%, and is maintenance-free; internally it has a pure lead construction and contains proprietary elements. The case material is ABS (UL 94-HB), and the terminal is F2 terminal - Faston Tab 250. Dimensions: length 151.0±2.0 mm, width 98.0±1.0 mm, height 98.4±1.5 mm; mass 4.33 kg. Electrically, the nominal voltage is 12 Vdc, and the rated capacity is 14 Ah (1.75 VPC @25°C, 20hr-rate). Under different discharge conditions, the capacities are 13.36 Ah (8-Hr 1.75 VPC @25°C), 14.08 Ah (20-Hr 1.75 VPC @25°C), and 13.12 Ah (8-Hr 1.80 VPC @25°C). The maximum charging current is 4.20 A, the maximum discharge current is 180 A, the short-circuit current is 542 A, and the internal resistance is 10.0 mΩ; the equalization charge voltage at 25°C is 14.4 to 15.0 Vdc/battery. In terms of service life, at 25°C, 100%DOD can reach 450 cycles, and 30%DOD can reach 1800 cycles. Operating temperature: nominal 25°C; discharge allowed from -15°C to 50°C; charging and storage allowed from -15°C to 40°C. Self-discharge performance: when stored at 25°C for 90 days, capacity loss is below 10%; it can be stored for up to 6 months and should be fully charged before use; if storage temperature is above 25°C, charge it earlier. Manufacturing references include IEC 60254-1:2005 and IEC 60254-2:2008, and it is UL1989 Recognized (MH14533). The above parameters and certifications are from the product documentation; actual matching should take into account specific equipment requirements and operating environment.
