Product details

CSB EVH12390 is a 12V valve-regulated sealed lead-acid battery belonging to the EVH series, utilizing Absorbent Glass Mat (AGM) technology with a maximum gas recombination efficiency of up to 99%, featuring a maintenance-free design. Its 20-hour rate nominal capacity (1.75VPC @25°C) is 39Ah, and the 8-hour rate capacity is 35.68Ah at 1.75VPC @25°C and 35.20Ah at 1.80VPC @25°C; in terms of dimensions, length 195.6mm, width 130.0mm, height 178.3mm, weight approximately 11.50kg, and case material ABS (UL 94-HB). In terms of electrical specifications, the EVH12390 can withstand a maximum charging current of 11.70A and a maximum discharge current of 400A, with a short-circuit current of 987.5A and internal resistance of 8.9mΩ; the equalization voltage at 25°C is 14.4-15.0Vdc/cell. The terminals are B5 type, compatible with M6 nuts and bolts, with a terminal torque of 5.10±1.0 N·m. Operating temperature conditions are as follows: discharge allows -15°C to 50°C, charge/storage allows -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 up to 400 cycles (100% depth of discharge) or 1800 cycles (30% depth of discharge). The self-discharge rate is low, with less than 10% self-discharge after 90 days at 25°C, and a maximum storage time of 6 months, though a full charge is required before use; if the storage temperature exceeds 25°C, charge in advance. The EVH12390 uses a pure lead construction and proprietary elements, meets IEC 60254-1:2005 and IEC 60254-2:2008 standards, and is UL1989 certified (MH14533). As a member of the EVH series, this product improves cycle life and cycle endurance over the EVX series, making it suitable for electric mobility equipment requiring frequent charging and discharging.
