FAQs
What devices are 500mAh–1000mAh lithium-ion batteries mainly used for?
This capacity range is widely used in wireless earphone charging cases, smartwatches, portable medical monitoring devices, smart remote controls, electronic pens, GPS trackers, mini game consoles, pocket translators, mini cameras, and other portable products that require extended runtime.
What is the nominal voltage and full-charge voltage of these batteries?
The nominal voltage is 3.7V, the full-charge voltage is 4.2V, and the cut-off discharge voltage is typically 2.75V–3.0V. These values can be adjusted based on the protection circuit design for different applications.
Do these batteries have a high self-discharge rate? Will they lose power if not used for a long time?
High-quality lithium-ion batteries have a monthly self-discharge rate of less than 3%, meaning they can retain most of their charge even after long periods of non-use. For long-term storage, it is recommended to keep them charged at 40%–60% and stored in a cool, dry place.
Can the batteries be connected in parallel or series?
Yes. Parallel connections can increase capacity, while series connections can increase voltage. However, cells with good consistency must be used, along with a proper BMS (Battery Management System), to avoid imbalance and safety risks.
What is the approximate weight and size of these batteries?
A 500mAh battery typically weighs around 8–12g, while a 1000mAh battery weighs about 15–20g. The exact weight depends on the shape and packaging design. Their compact size makes them suitable for lightweight electronic devices.
