Product details

The CSB EVH12140 belongs to the EVH series; the product type is a 12V Top Terminal VRLA-AGM battery, and the official application field is electric mobility. This series is an upgrade series for electric mobility, offering improved cycle life and cycle endurance compared with the EVX series, and is suitable for electric mobility or deep-cycle applications. In terms of electrical parameters, the EVH12140 has a voltage of 12 Vdc and a nominal capacity of 14 Ah (1.75 VPC @25°C, 20hr-rate). Capacities under different discharge conditions 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 equalizing charge voltage is 14.4 to 15.0 Vdc/battery (25°C). The battery uses a valve-regulated sealed lead-acid structure and absorbed glass mat technology, with a gas recombination efficiency of up to 99%, and is maintenance-free. The product uses pure lead construction and proprietary elements, the case material is ABS (UL 94-HB), and the terminal type is F2 terminal - Faston Tab 250. Dimensions are length 151.0±2.0 mm, width 98.0±1.0 mm, height 98.4±1.5 mm, and weight 4.33 kg. In terms of design life, the EVH12140 can reach 450 cycles (100%DOD) or 1800 cycles (30%DOD) at 25°C. The operating temperature range is: nominal 25°C, discharge -15°C to 50°C, charge and storage -15°C to 40°C. For self-discharge, capacity loss is less than 10% after 90 days of storage at 25°C, and it can be stored for up to 6 months; it must be fully charged before use; if the storage temperature is above 25°C, it should be charged sooner. The product is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008, and is UL1989 Recognized (MH14533). The above parameters and certification information are from the product data, and in actual use they should be matched to specific equipment requirements and operating environment.
