Battery Lithium Ion 18650 Rechargeable Battery 3600mAh 3.7v With Flat Top
The 18650 lithium-ion battery is a widely used cylindrical cell with a 3600mAh capacity and 3.7V nominal voltage. It measures 18mm in diameter and 65mm in length, making it slightly larger than a standard AA battery. Due to its high energy density and ability to deliver substantial discharge currents, it is found in various devices such as:
Flashlights: For high-performance lighting solutions requiring long runtimes.
Laptops: Powering portable computers due to its reliable energy storage and compact form.
Electric Vehicles: For electric car batteries, including Tesla, which uses 7180 of these cells in its vehicles to provide long driving ranges.
Key Features:
Energy Density: High energy density, allowing more energy to be stored in a smaller space, making it ideal for portable devices.
Discharge Capabilities: Can handle high discharge rates, which is critical for power-intensive applications.
Reliability: Known for its long lifespan, but requires proper handling to avoid safety issues.
Safety Considerations:
Fire Hazards: Like any lithium-ion battery, improper handling, overcharging, or discharging beyond recommended limits can result in overheating or fire. It's essential to choose batteries with built-in protections and use them in compatible circuits.
Correct Selection: Ensure the battery chosen matches the device’s power requirements and voltage needs to avoid risks.
