We also maintain close partnerships with raw material suppliers across the region, ensuring that our manufacturing never suffers from avoidable bottlenecks. To learn more about our corporate history, facility details, and quality infrastructure, we invite you to visit our About Us page, which outlines the company profile in full.

One of the key reasons businesses choose us is our diverse portfolio that covers nearly every demand found in modern electronic design. When engineering teams ask about the types of lithium batteries available for their project, we typically lead with our CR series, which includes coin and cylindrical cells built for compact, low-drain applications. These primary cells deliver stable voltage output over extended shelf life, making them ideal for remote controls, key fobs, and memory backup circuits. For applications that require repeated charging cycles, we offer a comprehensive line of rechargeable li-ion cells in 18650, 26650, and custom prismatic formats. Each variant is manufactured with cathode and electrolyte chemistries that balance energy density against thermal stability, so customers never have to compromise on safety to achieve high capacity.

Beyond conventional cells, we also specialize in a lithium polymer battery line that provides ultra-thin, flexible form factors suited to wearables and compact IoT gadgets. Our high-temperature li-ion battery series, meanwhile, is engineered to operate reliably in environments reaching 85°C and above, a requirement commonly seen in automotive sensors and industrial telemetry. Each product family is accompanied by detailed specification sheets covering nominal voltage, discharge rate, operating temperature range, and dimensional tolerances, allowing engineers to validate compatibility before ordering. Whether you need a simple 3V coin cell or a multi-cell pack with sophisticated protection circuitry, our Products catalog can be filtered by category to help you locate the exact match. Furthermore, we can produce lithium iron phosphate variants for customers who prioritize exceptionally long cycle life and intrinsic chemical stability in stationary or heavy-duty applications.

We also monitor emerging chemistries closely, including the growing interest around the catl sodium ion battery technology that has captured headlines in recent years. While sodium-based systems hold promise for large-scale energy storage due to their lower material costs, our current li-ion portfolio remains the superior choice for portable devices where volumetric energy density and weight are primary constraints. The breadth of our catalog means that a single conversation with our engineers can resolve questions about voltage platforms, discharge characteristics, and physical mounting requirements. No matter which cell type you select, every product is traceable back to a defined quality standard and documented production history. This level of transparency gives our clients complete confidence that the components they integrate into their systems will perform exactly as specified.

Quality in the battery industry is not an abstract concept; it is a measurable outcome of disciplined engineering, precise manufacturing, and relentless verification. Shenzhen Huagreen Technology holds ISO9001 for its quality management system and ISO14001 for environmental stewardship, while our hazardous goods handling procedures comply with UN38.3 transport requirements. Every batch of li-ion battery cells undergoes formation, aging, and capacity grading before it is approved for shipment, ensuring that weak cells are systematically eliminated. Our in-house laboratory performs accelerated cycle testing, high-low temperature exposure, and short-circuit analysis on representative samples from each production lot. By combining these certifications with a strict incoming-material inspection program, we deliver a defect rate that consistently meets the expectations of discerning global buyers.

Behind our quality assurance lies an R&D department staffed by electrochemical engineers who have decades of combined experience in cell design and failure analysis. We operate fully automated assembly lines equipped with precision winding, laser welding, and electrolyte filling stations that reduce human error and improve batch-to-batch consistency. The synergy between our engineering team and automated equipment enables us to fine-tune electrode formulations and separator thickness for specific customer applications. Long cycle life is a particular point of pride: many of our rechargeable li-ion products exceed 1,000 charge-discharge cycles at 80% capacity retention under laboratory conditions. These technical strengths, fully documented in our performance reports, are the reason why clients repeatedly return to us for their most demanding energy storage projects.

Off-the-shelf cells can only go so far; truly successful product designs often demand a li-ion battery pack that is customized to meet unique mechanical and electrical constraints. Our OEM and ODM services begin with a detailed consultation where our engineers evaluate your required capacity, nominal voltage, peak discharge current, and physical envelope. From there, we design the cell arrangement, select the appropriate protection circuit module, and specify connectors and wiring harnesses that align with your existing assembly process. We also offer a range of PCB options, including overcharge, over-discharge, and short-circuit protection features, as well as smart battery management functionality for advanced applications. This collaborative approach ensures that the final power source integrates seamlessly rather than requiring your team to redesign around a standard catalog cell.

The flexibility of our manufacturing platform allows us to accommodate small pilot runs as well as high-volume mass production without sacrificing lead time or quality. For clients developing a lithium polymer battery with an unusual footprint, we can adjust cell thickness, width, and tab locations to fit within the tightest product enclosures. Likewise, customers requiring high-rate discharge for power tools or drones benefit from customized electrode designs that lower internal resistance and minimize heat generation. We treat every customization project as a genuine partnership, providing DFM feedback early in the process so that potential manufacturability issues are resolved before tooling begins. Throughout development, we share progress updates and technical documentation that keeps your procurement and engineering teams fully informed at every milestone.

The true measure of a battery's worth is how reliably it performs in the real-world devices that depend on it. In the medical field, our li-ion battery cells power infusion pumps, portable patient monitors, and diagnostic instruments where power failure is simply not an option. For the Internet of Things, we supply low-self-discharge coin cells and compact rechargeable packs that keep sensors, trackers, and smart home hubs operating for years without maintenance. The security industry relies on our batteries for wireless alarm panels, surveillance cameras, and electronic locks, all of which require stable voltage delivery even during brief power interruptions. Our portable consumer electronics customers range from audio equipment makers to handheld gaming manufacturers, each benefiting from our ability to match chemistry and form factor to their device architecture.
