I. Core Product Parameters

• Product Model: 156825 16mAh (The model code corresponds to the battery size, facilitating product adaptation and inventory management)
• Nominal Voltage: 3.7V (Standard lithium battery operating voltage, suitable for the power supply needs of most smart wearable devices, with stable voltage output and no obvious fluctuations to ensure the normal operation of the device)
• Nominal Capacity: 16mAh (Accurately matches the power consumption needs of micro devices such as smart rings, enabling long-term battery life in low-power mode, balancing volume and battery life capacity, and avoiding excessive battery volume caused by too large capacity)
• Battery Size: 1.5×6.8×25mm (Curved design, 1.5mm in thickness, 6.8mm in width, 25mm in length, which can be perfectly embedded in the narrow space of smart rings without affecting the overall appearance and wearing comfort of the device)
• Charging Temperature Range: 0～45℃ (It is recommended to charge at room temperature, avoid charging in high or low temperature environments to prevent battery bulging, leakage and extend battery service life)
• Discharging Temperature Range: -20～60℃ (It has excellent high and low temperature discharge performance, can adapt to different environmental scenarios, and can discharge stably even in low temperature environments, ensuring the normal operation of the device in harsh environments)
• Battery Type: Polymer curved lithium battery (Adopting high-quality lithium polymer materials, it has high energy density and strong safety, no memory effect, can be charged at any time, no need to fully discharge before charging)
• Cycle Life: ≥300 times (Under normal charge-discharge cycles, the capacity can still maintain more than 80% of the initial capacity after 300 uses, meeting the long-term use needs of smart devices)

II. Core Product Features

1. Curved Custom Design: Tailor-made for devices with curved bodies such as smart rings, it fits the internal structure of the device, is easy to install, does not take up extra space, and avoids installation looseness, poor contact and other problems caused by inconsistent battery shape.
2. High Safety Guarantee: Built-in four-fold protection mechanisms of overcharge, over-discharge, over-current and short circuit, which effectively prevent safety hazards such as battery bulging, leakage and fire caused by abnormal charging and discharging, and meet the safety use standards of small smart devices.
3. Stable Battery Life Performance: Stable voltage output and gentle discharge curve can provide continuous and stable power supply for devices such as smart rings, avoiding device freezes, shutdowns and other situations caused by voltage fluctuations, and adapting to the low-power operation mode of the device.
4. Small, Thin and Easy to Adapt: Small in size and light in weight, it will not increase the wearing burden of the smart ring. At the same time, it is compatible with the installation sizes of various small smart wearable devices, with strong versatility, and can flexibly adapt to smart rings and micro devices of different brands and models.
5. Wide Temperature Adaptability: The discharge temperature covers -20～60℃, which can adapt to different ambient temperatures such as indoor and outdoor. Whether in cold areas or high-temperature environments, it can stably play a power supply role, adapting to scenarios with high environmental adaptability requirements such as medical equipment.
6. No Memory Effect: Supports charging at any time, no need to deliberately discharge before charging, which is convenient for daily use, and at the same time reduces battery loss and extends the overall service life of the battery.
