FAQs
What devices are 2000mAh~12000mAh Li-ion batteries mainly used in?
Common applications include tablets, laptops, drones, smart robots, power banks, handheld medical devices, industrial terminals, VR devices, portable projectors, outdoor lighting, and small energy storage systems.
What is the biggest difference between these batteries and smaller capacity batteries?
The main differences are higher energy storage capacity, longer runtime, and stronger discharge current support. Additionally, larger batteries require stricter thermal management and protection circuits to ensure safety.
Can a single 2000mAh~10000mAh cell directly replace multiple smaller cells?
In some devices, yes. It depends on voltage requirements and structural design. A larger single cell can reduce the number of parallel connections and simplify management, but higher voltage applications still require series connections.
What is the typical cycle life of these batteries?
Under standard usage conditions, the cycle life is typically 500–800 cycles with ≥80% capacity retention. With long-life cell formulations, this can be extended to over 1000 cycles, suitable for long-term use.
What should be noted when charging these batteries?
Large-capacity batteries require higher charging currents, so it is recommended to use a dedicated charger with constant current/constant voltage (CC/CV) control. Avoid low-quality adapters or exceeding the rated current, as this may cause overheating or shorten lifespan.
Are there special requirements for transporting these batteries?
Yes. Batteries over 100Wh must comply with UN38.3 testing and certification, and follow IATA DGR dangerous goods regulations for air transport. Single 2000mAh–10000mAh cells are usually under 100Wh, but battery packs may exceed this limit.
What safety certifications do these batteries have?
Common certifications include CE, RoHS, UN38.3, MSDS, and IEC62133. Some industries may also require UL1642 or UL2054. For exports to Europe and the U.S., these certifications are essential to ensure compliance and safety.
Can manufacturers provide customized battery solutions?
Yes. Customization is available for capacity, size, discharge rate, operating temperature range, protection circuits, and connector design. Complete solutions including battery pack + BMS + casing can also be provided.
