Product details
The EVH12140 is a product of CSB's EVH series, classified as a 12V Top Terminal VRLA-AGM battery, officially positioned for electric mobility applications. As an upgrade series for electric mobility, it offers better cycle life and cycle durability than the EVX series, making it suitable for electric mobility or deep cycle use environments.
In terms of electrical specifications, the EVH12140 provides 12 Vdc voltage and a nominal capacity of 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 range is 14.4 to 15.0 Vdc/battery (25°C).
This battery combines a valve regulated sealed lead acid structure with Absorbent Glass Mat technology, achieving a gas recombination efficiency of up to 99% for maintenance-free operation. It features pure lead construction with proprietary elements, an ABS case (UL 94-HB), and F2 terminal - Faston Tab 250. Dimensions are 151.0±2.0 mm in length, 98.0±1.0 mm in width, and 98.4±1.5 mm in height, with a weight of 4.33 kg.
Regarding design life, the EVH12140 can achieve 450 cycles (100%DOD) or 1800 cycles (30%DOD) at 25°C. Temperature adaptability: nominal 25°C, discharge -15°C to 50°C, charge and storage -15°C to 40°C. Self-discharge performance: stored at 25°C for 90 days, capacity loss is less than 10%, and it can be stored for up to 6 months; it must be fully charged before use. If the storage temperature exceeds 25°C, charge it in advance.
The product is manufactured according to IEC 60254-1:2005 and IEC 60254-2:2008 standards, and is UL1989 Recognized (MH14533). The above parameters and certification information are derived from product data; actual use requires matching specific equipment requirements and operating conditions.
