Product details

The CSB EVH12240 from Hitachi Energy Technology is a 12V valve-regulated sealed lead-acid battery in the EVH series, classified as a 12V Top Terminal VRLA-AGM product. This series is designed for electric mobility needs, and the manufacturer positions it as an advanced version of the EVX series, with emphasis on improved cycle life and cycling durability. The battery uses absorbent glass mat (AGM) technology with a gas recombination efficiency of up to 99%, and features a pure lead construction with proprietary formulation elements, requiring no maintenance overall. In terms of capacity, the EVH12240 has a nominal capacity of 24 Ah at the 20-hour rate, 1.75 VPC, and 25°C. At 25°C, the 8-hour rate capacity at 1.75 VPC is 24.72 Ah, the 20-hour rate capacity at 1.75 VPC is 25.60 Ah, and the 8-hour rate capacity at 1.80 VPC is 24.48 Ah. The maximum charging current is 7.20 A, the maximum discharge current is 320 A, the short-circuit current is 848 A, and the measured internal resistance is 8.6 mΩ. The equalization voltage range at 25°C is 14.4 to 15.0 Vdc/battery. In terms of dimensions, the battery is 181.0±2.0 mm long, 76.2±1.0 mm wide, and 170.0±2.0 mm high, with a weight of 7.55 kg. The terminal uses an I1 terminal to accept M5 bolt, with a torque value of 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. The case material is ABS, and the flame retardant rating complies with UL 94-HB. Cycle life data: at 25°C, the design life at 100%DOD is up to 350 cycles, and the design life at 30%DOD is up to 1800 cycles. In terms of temperature adaptability, the nominal temperature is 25°C, discharge is allowed from -15°C to 50°C, and charging and storage are between -15°C and 40°C. Self-discharge performance: after 90 days of storage at 25°C, self-discharge is less than 10%, and storage is possible for up to 6 months; the battery must be fully charged before use. If the storage temperature exceeds 25°C, it should be charged in advance. This product is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008 standards, and has obtained UL1989 Recognized (MH14533) certification. Combining pure lead construction, AGM technology, and long cycling durability, the EVH12240 can be used in electric mobility and deep cycle scenarios, maintaining stable operation under specified temperature and charging conditions.
