Product details

The CSB EVH12390 belongs to the EVH series and is a 12V valve-regulated sealed lead-acid battery featuring absorbed glass mat (AGM) technology, with a gas recombination efficiency of up to 99% and a maintenance-free design. Its nominal capacity is 39Ah (20-hour rate, 1.75VPC @25°C), and the 8-hour rate capacity is 35.68Ah (1.75VPC @25°C) or 35.20Ah (1.80VPC @25°C). The battery dimensions are 195.6mm length, 130.0mm width, and 178.3mm height, weighing approximately 11.50kg, with an ABS (UL 94-HB) case material. In terms of electrical performance, the EVH12390 has a maximum charging current of 11.70A, a maximum discharge current of 400A, a short-circuit current of 987.5A, and an internal resistance of 8.9mΩ. The equalizing charge voltage is 14.4-15.0Vdc/cell (25°C). The terminal type is B5, accepting M6 nuts and bolts, with a terminal torque of 5.10±1.0 N·m. The battery's operating temperature range is: discharge -15°C to 50°C, charge/storage -15°C to 40°C, nominal temperature 25°C. This battery is designed for electric mobility or deep-cycle applications, with a cycle life at 25°C of 400 cycles (100% depth of discharge) or 1800 cycles (30% depth of discharge). It has a low self-discharge rate, with less than 10% self-discharge after 90 days of storage at 25°C, and can be stored for up to 6 months, but requires a full charge before use; if the storage temperature exceeds 25°C, it should be charged earlier. The EVH12390 features a pure lead construction and proprietary elements, complies with IEC 60254-1:2005 and IEC 60254-2:2008 standards, and is certified to UL1989 (MH14533). As an EVH series product, it improves cycle life and cycling endurance over the EVX series, making it suitable for electric mobility equipment requiring frequent charge and discharge.
