18650 lithium ion rechargeable battery
The 18650 lithium ion rechargeable battery represents a breakthrough in portable power technology, featuring a cylindrical design measuring 18mm in diameter and 65mm in length. This standardized battery format has become the industry benchmark for high performance energy storage solutions. With typical capacities ranging from 2000mAh to 3500mAh, these batteries deliver consistent power output at 3.7V nominal voltage. The advanced lithium ion chemistry enables exceptional energy density, allowing for extended operation times while maintaining a compact form factor. These batteries incorporate sophisticated safety features, including built in protection circuits that prevent overcharging, over discharging, and short circuits. The 18650 battery's robust construction ensures reliable performance across thousands of charging cycles, making it ideal for demanding applications. Common uses include laptop computers, power tools, electric vehicles, and high powered LED flashlights. The cells feature low self discharge rates, typically losing only 2 to 3 percent of their charge per month when stored, and can operate effectively across a wide temperature range.
