Product details

The CSB EVH12390 is a 12V Valve Regulated Sealed Lead Acid battery in the EVH series. It adopts AGM (Absorbent Glass Mat) technology, achieving a gas recombination efficiency of up to 99%, and features a maintenance-free design. Nominal capacity is 39Ah (20-hour rate, 1.75VPC @25°C), with a capacity of 35.68Ah (1.75VPC @25°C) or 35.20Ah (1.80VPC @25°C) at the 8-hour rate. Dimensions: 195.6mm (L) × 130.0mm (W) × 178.3mm (H), weight approximately 11.50kg, case made of ABS material (UL 94-HB). In terms of electrical parameters, the battery has a maximum charge current of 11.70A, maximum discharge current of 400A, short-circuit current of 987.5A, and internal resistance of 8.9mΩ. Equalization charge voltage is 14.4-15.0Vdc/cell (25°C). The B5 terminals accommodate M6 nuts and bolts, with a terminal torque of 5.10±1.0 N·m. Operating temperature range: discharge -15°C to 50°C, charge/storage -15°C to 40°C, nominal temperature 25°C. This battery is intended for electric mobility or deep cycle applications. At 25°C, cycle life is 400 cycles (100% depth of discharge) or 1800 cycles (30% depth of discharge). Self-discharge rate is low: stored at 25°C for 90 days, self-discharge is less than 10%, and it can be stored for up to 6 months, but must be fully charged before use; if storage temperature exceeds 25°C, charge in advance. The EVH12390 uses a pure lead construction and proprietary elements, complies with IEC 60254-1:2005 and IEC 60254-2:2008 standards, and is UL1989 certified (MH14533). As a product in the EVH series, it enhances cycle life and cycling durability based on the EVX series, making it suitable for electric mobility equipment requiring frequent charge and discharge.
