Nitecore NL18650A2000mAh High Discharge IMR BatterySecure, Reliable IMR Power for Heavy Duty ElectronicsWhen it comes to powering demanding electronic devices, the Nitecore NL18650A is the perfect choice for a reliable high-drain energy source. Users of LED flashlights, and power tools will enjoy the 30A Discharge Current that keeps a steady stream of power for their devices. Featuring IMR chemistry, this battery is incredibly consistent and can be safely used without the inclusion of a PCB protection circuit. The NL18650A is an 18650 sized battery that produces 3.6 Volts of power and can store up to 2000mAh of energy, a great battery for lights, medical devices and related electronics. The NL18650A contains IMR Lithium-ion Manganese Oxide (LiMn204) chemistry, which is favored in applications and devices that require high-discharge currents. IMR batteries use a cathode made from Lithium Manganese Oxide formed in a three-dimensional spinel structure which improves ion flow. This structure provides lower internal cell resistance, which speeds up charging and expedites high-current discharging, making these batteries perfect for high-drain electronics, power tools, lights, and medical devices. Furthermore, these batteries are rechargeable which help you save money and do the environment a favor by reusing your drained cells. If you do not have a charger for your specific battery type, we have the power! The Nitecore Intellicharge F1 Smart Battery Charger is our newest and most convenient charger for IMR batteries.Specifications: Typical Capacity: 2000mAh Nominal Voltage: 3.6V Discharge Voltage: 2.8V Charging Voltage: 4.20+-0.05V Max Continuous Discharging Current: 30A Dimensions: Length: 66.9mm Diameter: 18.30 Weight: 46g
