We performed a battery refresh on the electric forklifts at the Renault-Nissan Yokohama plant. The results were remarkable, as the batteries were successfully recovered, extending the use of the forklift batteries for an additional three years. Notably, this caught the attention of the Renault-Nissan Factory’s Improvement team and was reported as a recommended improvement method for the factory. In Japan, there are COREDZ service providers who specializes in forklift battery refresh, and their customers highly appreciate the effectiveness.
