CoinCell Battery (Shenzhen CoinCell Battery Co., Ltd.) is a lithium-ion battery solutions company founded in 2018. Its core focus is the R&D, production, and sales of micro lithium batteries. According to its website, it mainly serves small electronic product applications such as TWS earbuds, hearing aids, medical devices, smart wearables, and e-cigarettes. It is a hardware manufacturing and battery supply-chain website rather than a consumer e-commerce platform or online tool.
Its product lines include rechargeable coin-type lithium batteries, cylindrical lithium batteries, lithium manganese coin cells, lithium polymer batteries, battery packs, and smart battery packs. The website highlights automated production lines, X-Ray inspection, safety and reliability testing under UL/IEC standards, and a MES system that enables full-process traceability of quality data, materials, equipment, and key operators. Its standard models are claimed to have certifications such as UL1642, IEC62133, and UN38.3, along with export and transportation documents such as REACH and MSDS.
The official website does not provide unit prices, MOQ, sample policies, or lead-time information. The typical model is likely B2B inquiry-based quoting. Actual pricing will most likely depend on cell size, capacity, discharge rate, safety certifications, whether a custom protection board/battery pack is required, purchase volume, and project stage. Buyers need to contact the company’s sales or engineering team to obtain specifications and quotations.
The advantages are its clear focus on micro lithium batteries and well-defined niche positioning. With an annual production capacity of over 160 million units, its team and engineering background appear relatively industrialized. It also has systems such as ISO9001, ISO14001, and ISO13485, which may be attractive for medical and export-oriented projects. The drawbacks are that the website contains a fair amount of repetitive content and lacks hard selection materials such as downloadable datasheets, a complete model list, discharge curves, cycle-life data, certification numbers, and customer case studies, resulting in limited procurement transparency.
It is suitable for manufacturers of earbuds, hearing aids, wearables, small medical devices, e-cigarettes, and IoT hardware conducting preliminary supplier screening, especially R&D, procurement, and supply-chain teams that need micro high-energy-density cells or customized battery packs. It is not suitable for individual retail buyers or small-volume users who need online ordering.
The domain is .cn, and the company is located in China, so it should normally be directly accessible from mainland China. Overall, CoinCell looks more like an English-language showcase site for a traditional manufacturing company. Its technical and production-capacity selling points are clear, but offline due diligence, sample testing, and certification verification are still necessary before introducing it into a project.
