Product details

The CSB EVH12240 is a 12V valve-regulated sealed lead-acid battery belonging to the EVH series, with a product type of 12V Top Terminal VRLA-AGM. This series is aimed at e-mobility applications and is officially positioned as an upgraded series that improves cycle life and cycling endurance over the EVX series. The battery uses absorbed glass mat technology with gas recombination efficiency of up to 99%, and adopts pure lead construction with proprietary formulation elements, making it maintenance-free overall. In terms of capacity, the EVH12240 has a nominal capacity of 24 Ah (20-hour rate, 1.75 VPC, 25°C). At 25°C, the 8-hour rate 1.75 VPC capacity is 24.72 Ah, the 20-hour rate 1.75 VPC capacity is 25.60 Ah, and the 8-hour rate 1.80 VPC capacity 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 internal resistance is 8.6 mΩ. The equalizing charge voltage is 14.4 to 15.0 Vdc/battery (25°C). The battery dimensions are length 181.0±2.0 mm, width 76.2±1.0 mm, height 170.0±2.0 mm, and weight 7.55 kg. The terminal type is I1 terminal to accept M5 bolt, and the terminal torque is 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in or 3.0±0.6 N·m. The case material is ABS, meeting UL 94-HB flame retardant rating. In terms of cycle life, the design life at 25°C is 350 cycles at 100%DOD and 1800 cycles at 30%DOD. Regarding operating temperature, the nominal temperature is 25°C, the discharge temperature range is -15°C to 50°C, and the charging and storage temperature range is -15°C to 40°C. Regarding self-discharge, self-discharge is less than 10% after 90 days at 25°C, storage is possible for up to 6 months, a full charge is required before use, and if the storage temperature is above 25°C, charging should be done sooner. This product is manufactured in accordance with IEC 60254-1:2005 and IEC 60254-2:2008 standards, and is UL1989 Recognized (MH14533). With pure lead construction, AGM technology and high cycling endurance, the EVH12240 is suitable for e-mobility and deep-cycle application scenarios, and can operate stably under the specified temperature and charging conditions.
