Mei Mei Battery: A Global Leader in Lead-Acid Battery Innovation and Quality Founded in 1992, Mei Mei Battery has grown into a world-renowned high-tech enterprise specializing in the research, development, production, and sales of lead-acid batteries. With an initial investment of $30 million and a facility spanning approximately 60,000 square meters, our commitment to excellence began with a solid foundation. In 2006, we expanded our presence by establishing a second production base in the Xingsha National Economic and Technological Development Zone in Changsha, Hunan Province, China. Today, we are proud to have a dedicated team of over 2,000 experienced employees and a stable management structure. Our monthly production capacity is equivalent to 2.5 million units of 7Ah batteries, serving a diverse customer base across Asia, Europe, and the Americas. Our mission is clear: to provide high-quality lead-acid batteries and services to our customers worldwide. For over two decades, we have been dedicated to the Valve-Regulated Lead-Acid (VRLA) battery industry, successfully developing and producing AGM, Gel, and Flooded battery types. We firmly believe that superior products rely on consistent quality management from raw materials to finished goods. This philosophy is supported by our experienced R&D team, efficient production personnel, and a comprehensive, high-execution quality control and assurance system. **Unwavering Commitment to Quality and Innovation** Quality is the cornerstone of our operations. To achieve the highest standards, we continuously invest in our R&D laboratories, optimize PP/ABS cell jar designs, research battery materials and production efficiency, and implement automated QA/QC equipment. Our innovative design processes, complete production lines, and high-standard QA/QC systems are all meticulously crafted to meet and exceed customer expectations. Our R&D department is a core competitive advantage, comprising three key sections: basic research, battery design, and support & testing. With two dedicated labs at our headquarters—a basic laboratory and a battery testing laboratory—every product is designed and rigorously tested by our engineering team before reaching our clients. This ensures that we deliver robust and durable lead-acid batteries for the global market. Our quality assurance extends beyond design to encompass every aspect of manufacturing. We implement a comprehensive, "A-to-Z" quality monitoring system. Key factors in our quality success include conducting most production processes in-house—such as producing lead alloys, molds, parts, and cell jars—to maintain strict control. We continuously invest in advanced R&D, inspection, and production equipment, improve processes, enhance automation, and maintain complete data records for traceability and analysis. Our efforts are supported by a mature, meticulous, and experienced management team operating within a comfortable work environment, all united in a relentless pursuit of high quality. Our commitment is validated by prestigious certifications. Mei Mei Battery is certified under ISO9001, ISO14001, and OHSMS18001 management systems. Our products carry UL and CE marks, and have obtained additional certifications like VdS, NEBS, TLC, and TSE for various application fields. **Advanced Product Portfolio** We offer a wide range of battery technologies to suit diverse needs: * **VRLA-AGM Batteries:** Our core technology employs an oxygen recombination principle, making batteries maintenance-free. Our extensive series include BP (general purpose), EP/EB/EVP (for e-bikes/e-scooters), HR/SHR (for high-rate UPS), BPL/MPL (long float life for telecom/solar), and FTB/MSB/MSU (for high-power telecom applications). * **Gel Batteries (Zelus Series):** Featuring a non-fluid gel electrolyte, these batteries solve issues related to electrolyte evaporation and leakage. They offer superior performance in extreme temperatures, under vibration, and shock, with a calcium-based grid for reduced gas generation. * **Traction Batteries (Spur-B.B Series):** Designed for reliability and long cycle life in industrial applications like material handling and electric vehicles. They feature robust construction, automatic watering systems, and electrolyte circulation to prevent stratification. **Environmental Responsibility and Sustainability** As a responsible global manufacturer, we prioritize environmental protection. Our comprehensive environmental actions include centralized wastewater treatment with online monitoring, advanced air purification and dust collection systems (including dedicated dust/acid mist filters and employee air showers), and centralized recycling of solid waste through government agencies. We continuously work with our management and R&D teams to adopt the latest environmental protection solutions. We also operate a battery recycling program, inviting customers to return spent lead-acid batteries to us for proper processing. **Corporate Social Responsibility** Our responsibility extends to society. We actively support communities by funding children in remote areas through initiatives like building roads and libraries, and donating supplies. Our "Light of Hope" program, winter relief efforts, and the Mei Mei Battery Scholarship aim to provide housing, educational, and medical support to those in need. We have proudly participated in and supported global humanitarian initiatives such as Sorfin Yoshimura's "One Minute Feedback," Doctors Without Borders (MSF) campaigns, and Orbis's World Sight Day events. **Customer Support and Warranty** We stand firmly behind our products with a robust support system. Our technical support and after-sales service team works collaboratively with customers, sharing successful project experiences. We provide detailed answers to common technical questions about our VRLA, Gel, and Traction battery lines. Our limited warranty for B.B series batteries covers defects in materials and workmanship for 12 months from the date of shipment, subject to specific terms and conditions, including proper use, maintenance, and environmental factors. **Our Vision for the Future** For over 20 years, our relentless pursuit of quality has earned us a stellar reputation and numerous "Best Supplier" awards from clients worldwide. Our valuable assets are our strong R&D team, high-efficiency production technology, and unwavering commitment to quality. We are committed to the long-term development of the VRLA battery industry. We will continue to invest in high-tech production equipment, our experienced R&D team, and versatile production lines. Our goal is to provide powerful energy for a rapidly developing world while upholding our core values. We believe in offering excellent cost-performance through continuous process improvement, delivering highly reliable and consistent products. Our motto drives us forward: "We seek not merely to survive, but to continuously surpass ourselves." Your continued support and partnership are the strongest pillars of Mei Mei Battery's success.
