Focus on the research & development, production, sales & service of smart chargers & other charging devices
Dlyfull is a professional manufacturer of high-quality micro lithium pin type batteries. Our lithium pin type batteries mainly fall into two categories: rechargeable and non-rechargeable. Among them, rechargeable batteries are mainly used in various micro intelligent terminal products such as the Internet of Things (IoT), smart wearables, hearing aids, and smart pens. Non-rechargeable batteries are mainly applied to outdoor fishing tackle (such as electronic fishing floats, rod tip lights, fish luring lights, etc.), outdoor illuminated nocks, as well as luminous toys (including luminous badminton, luminous pickleball, etc.).
Dlyfull offers a full line of battery chargers and battery testers, from basic to intelligent models. Our chargers safely and efficiently charge all mainstream rechargeable batteries. The testers analyze battery health for both rechargeable and non‑rechargeable consumer batteries, helping users manage home battery life, improve efficiency, and reduce waste. All products meet strict global safety and compliance standards. Dlyfull delivers innovative, reliable charging and battery testing solutions trusted by discerning consumers worldwide.
Leveraging our small lithium pin battery’s unique design, we developed innovative night fishing and archery electronics. Rechargeable and reusable, they replace disposable chemical glow products, reduce waste, and make outdoor sports more enjoyable—eco‑friendly and sustainable
