production-stages
There are 24 control points in laboratories and at production site. Confidence in our products is a result of a thoughtful approach.
Quality-Complete Production Lines
To reach the excellent quality design, we continue to invest production facilities from R&D lab, battery construction for molding and PP/ABS injection optimization, material research for battery efficiency, automation productivity to QA/QC equipments. We have innovative design process and complete production lines with high standard QA/QC inspections to meet clients’ needs.
Innovative R&D Team
R&D Department is one of the core competences of B.B. Battery. It’s organized as sections of Researching, Designing, Supporting and Testing. Our engineering personnels are able to innovate solid and durable lead-acid battery product.
Laboratory
There are two laboratories facilitated with cutting edged equipment in Shantou Headquarter, every product is designed and tested by R&D Department before distributing to our customers. For R&D Department, we research and design high efficient and eco-friendly batteries. It is our goal to make the excellent battery products to global customers.
Quality Assurance
Following cutting edge design, manufacturing technology is another key factor for high quality. B.B. Battery has equipped with a number of features and techniques on it. In order to completely control quality, we adopt a series of QC/QA inspection standards and procedures. Accompanying with strict operations, we have earned remarkable reputation in lead-acid battery industry.
