The study addresses the operational challenges faced by small and medium-sized enterprises (SMEs) in automotive battery manufacturing. Previous research indicates inefficiencies in maintenance and quality control impacting productivity. This investigation aimed to overcome these challenges through the implementation of a Total Productive Maintenance (TPM) model tailored for battery manufacturers. The proposed model included structured phases of planning, testing, implementation, and validation to enhance equipment reliability and reduce downtime. Key findings demonstrated a significant improvement in operational efficiency by 13.85% and a decrease in non-conforming products by 25.58%. The study’s contribution lies in adapting TPM strategies to the specific context of battery manufacturing SMEs, offering a scalable framework for operational improvements. This research has implications for enhancing competitiveness and sustainability in the automotive supply chain. Future studies are encouraged to refine and expand this model in similar industrial sectors to foster continuous improvement.
