14500 battery AA rechargeable 3.7V 800mAH lithium-ion battery

The 14500 cylindrical lithium battery is a lithium-ion battery with a diameter of 14mm and a height of 50mm, with the "0" indicating that it is cylindrical in shape. Its size is similar to that of an AA battery. Compared to nickel-metal hydride (NiMH) batteries, the 14500 cylindrical lithium battery offers several advantages, including lighter weight, lower self-discharge, and superior discharge performance.

Description


The 14500 battery, also known as the AA lithium-ion battery, is a rechargeable power source designed to fit the size of a 

traditional AA battery.


 Unlike standard AA batteries, which typically use alkaline or nickel-based chemistries, the 14500 battery utilizes lithium-ion technology, 

offering a significantly higher voltage output. With a nominal voltage of 3.7V and a capacity of up to 800mAh,

 it is a popular choice for high-performance applications such as flashlights, remote controls, and various electronic devices.


Thanks to its high energy density and longer cycle life, the 14500 battery is commonly used in powerful LED flashlights, portable power banks,

 and other gadgets requiring reliable, long-lasting power. 

Moreover, because these batteries are rechargeable up to thousands of times, they provide an eco-friendly alternative to disposable batteries, 

helping to reduce waste and lower the environmental impact.
