This document contains a summary of typical issues in lead-acid battery production and proposed solutions. It discusses common problems such as rapid self-discharge due to impurities, low storage performance from moisture, rapid capacity loss during use, and early plate corrosion and frame fractures. Potential causes are analyzed for each issue, such as quality of raw materials, drying processes, and charger performance. The document then provides solutions like ensuring high quality sources, improving equipment cleaning and parameters, controlling moisture levels, and using suitable grid alloys and formulas. It also includes a briefing on Jinkeli's facilities, products, customers, and research and development center capabilities.
