Product details

For electric mobility and deep-cycle applications, the CSB EVH12390 can achieve 400 cycles in a 25°C environment (100% depth of discharge); if the depth of discharge is 30%, the cycle count can reach 1,800. Its self-discharge is low: after 90 days at 25°C, self-discharge is less than 10%; it can be stored for up to 6 months, but should be fully charged before being put back into use; when storage temperature exceeds 25°C, recharge is required earlier. This model belongs to the EVH series and is a 12V valve-regulated sealed lead-acid battery. It uses AGM (absorbent glass mat) technology, has gas recombination efficiency of up to 99%, and is a maintenance-free design. At 25°C and 1.75VPC, the 20-hour rate nominal capacity is 39Ah; the 8-hour rate capacity is 35.68Ah (1.75VPC @25°C) or 35.20Ah (1.80VPC @25°C). Dimensions are 195.6mm (L) × 130.0mm (W) × 178.3mm (H), weight is approximately 11.50kg, and the case material is ABS (UL 94-HB). For electrical parameters, the EVH12390 has a maximum charge current of 11.70A, a maximum discharge current of 400A, a short-circuit current of 987.5A, and an internal resistance of 8.9mΩ. At 25°C, the equalizing charge voltage is 14.4-15.0Vdc/battery. The terminal is B5 type, compatible with M6 nuts and bolts, with a torque requirement of 5.10±1.0 N·m. Temperature range: discharge -15°C to 50°C; charge/storage -15°C to 40°C; nominal temperature is 25°C. In terms of materials, the EVH12390 is made with a pure lead structure and proprietary elements, meets IEC 60254-1:2005 and IEC 60254-2:2008 standards, and is UL1989 certified (MH14533). Compared with the EVX series, the EVH series offers enhanced cycle life and cycle endurance, making it suitable for electric mobility equipment that requires frequent charging and discharging.
