Product details

EVH12150 belongs to CSB's EVH Series. Its product category is a 12V Top Terminal VRLA-AGM battery, and the official application is electric mobility. Compared with the EVX Series, the EVH Series offers improved cycle life and cycle endurance. This battery is based on a valve-regulated sealed lead-acid structure and uses Absorbent Glass Mat technology, with gas recombination efficiency up to 99%, and is maintenance-free by design; pure lead construction and a proprietary element formulation are also used, making it suitable for electric mobility or deep cycle applications. In terms of electrical parameters, the EVH12150 voltage is 12 Vdc, maximum charge current is 4.50 A, maximum discharge current is 180 A, short-circuit current is 576 A, and internal resistance is 10.5 mΩ; at 25°C, the equalization charge voltage is 14.4 to 15.0 Vdc/battery. For capacity, at 25°C and 1.75 VPC, the 20-hour rate nominal capacity is 15 Ah, the 20-hour rate actual capacity is 15.20 Ah, and the 8-hour rate capacity is 14.08 Ah; at 1.80 VPC and 25°C, the 8-hour rate capacity is 13.92 Ah. In terms of terminals and dimensions, the EVH12150 uses an F2 terminal (Faston Tab 250), the case material is ABS, and the flame retardant rating is UL 94-HB. The weight is 4.60 kg (10.14 lb), the length is 151.0±2.0 mm, the width is 98.0±1.0 mm, and the height is 101.8±1.5 mm. Temperature conditions: nominal temperature 25°C (77°F); discharge range -15°C to 50°C, and charge and storage range -15°C to 40°C. For design life, at 25°C, 100%DOD provides 450 cycles and 30%DOD provides 1800 cycles. For self-discharge, when stored at 25°C for 90 days, capacity loss is less than 10%, and storage for up to 6 months is possible; fully charge before reuse, and if storage temperature exceeds 25°C, charge earlier. In terms of manufacturing and certifications, the product is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008, and has obtained UL1989 Recognized (MH14533). Overall, the EVH12150 is suitable for electric mobility and deep cycle discharge; when operating at a nominal temperature of 25°C, cycle performance can meet the corresponding design level.
