Product details

The CSB EVH12240, part of the EVH series, is a 12V Top Terminal VRLA-AGM type Valve Regulated Sealed Lead Acid battery. This series is officially positioned as an upgraded version of the EVX series, primarily targeting electric mobility applications, with improvements in cycle life and cycling endurance. Its technical features include Absorbent Glass Mat, pure lead construction, and proprietary formulation elements, achieving a gas recombination efficiency of up to 99%, and it is completely maintenance-free. In terms of capacity data, the nominal capacity is 24 Ah measured at 25°C with 1.75 VPC at the 20-hour rate. Also at 25°C, the 8-hour rate at 1.75 VPC corresponds to 24.72 Ah, the 20-hour rate at 1.75 VPC corresponds to 25.60 Ah, and the 8-hour rate at 1.80 VPC is 24.48 Ah. The maximum charge 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. At 25°C, the equalization voltage must be controlled between 14.4 and 15.0 Vdc/battery. In terms of dimensions, the length is 181.0±2.0 mm, width 76.2±1.0 mm, height 170.0±2.0 mm, and weight 7.55 kg. The terminal uses an I1 terminal to accept M5 bolt, with a torque withstand of 30.4±6.1 Kgf·cm, 26.4±5.3 Lbf·in, or 3.0±0.6 N·m. The case is made of ABS material with a flame retardant rating of UL 94-HB. In terms of cycling performance, at 25°C the design cycle life at 100%DOD is 350 cycles, and at 30%DOD the design cycle life can reach 1800 cycles. Regarding temperature adaptability, the nominal temperature is 25°C, the allowable discharge range is -15°C to 50°C, and the allowable charge and storage range is -15°C to 40°C. Self-discharge performance: stored at 25°C for 90 days, self-discharge is less than 10%, and it can be stored for up to 6 months; it must be fully charged before use, and if the storage temperature exceeds 25°C, it needs to be charged earlier. In terms of manufacturing standards, this product complies with IEC 60254-1:2005 and IEC 60254-2:2008, and has obtained UL1989 Recognized (MH14533). With its pure lead construction, AGM technology, and strong cycling endurance, the EVH12240 can be used in electric mobility and deep cycle applications, maintaining stable operation under specified temperature and charging conditions.
