3.7V 300mAh 602030 Lithium Battery

The 3.7V 300mAh 602030 Lithium Battery is a compact, rechargeable lithium-ion cell designed for small electronic devices that require reliable, long-lasting power in a miniature package. This battery offers a nominal voltage of 3.7V and a rated capacity of 300mAh, making it suitable for low- to moderate-drain applications where space is limited.

Constructed using standard lithium-ion chemistry, the cell provides consistent discharge characteristics and efficient charge acceptance when used with an appropriate charger. It is designed to deliver stable performance across a typical operating range and benefits from the inherent advantages of lithium-ion technology, including a high energy-to-weight ratio and relatively low self-discharge compared with many other rechargeable chemistries.

This battery is commonly used in portable electronics such as compact sensors, wearable devices, backup power modules, small IoT nodes, and other applications that prioritize size and weight. When integrating the battery, follow manufacturer guidelines for charging currents, temperature limits, and safety measures. Use proper charging circuitry and, where required by the application, include protective components or battery management to prevent overcharge, overdischarge, and short circuits.

Handle and store the cell according to recommended safety practices: avoid mechanical damage, extreme temperatures, and exposure to liquids. Dispose of or recycle the battery in accordance with local regulations and electronic waste guidelines.
