CSB EVH12240, 12V, 24Ah Battery

The CSB EVH12240 valve-regulated lead-acid (VRLA) traction battery uses maintenance-free AGM (Absorbent Glass Mat) technology, enabling efficient gas recombination of up to 99%. Made from pure lead and proprietary components, it is designed for e-mobility and deep cyclic discharge applications. The construction complies with IEC 60254-1:2005 / IEC 60254-2:2008 standards and is certified to UL1989 (MH14533). The EVH series improves on the EVX with better cycle life thanks to specially designed energy storage for e-mobility such as electric scooters, recreational vehicles and many more. EVH is specifically designed for efficient discharges in cyclic applications. A special proprietary formula uses 99.99% pure lead ingot in the manufacture of lead oxide, lead plate grids and other lead components, all to ensure optimum high-speed performance. Optional flame-retardant ABS casing design. Complies with IATA/ICAO Special Provision A67 for air transport, classified under Amendment MG 27 as non-hazardous material for water transport and recognised by DOT as "dry cargo" under 49 CFR 171–189 for surface transport.
