More Details About 16340 Batteries
16340 batteries, also called CR123A rechargeable batteries, are lithium-ion rechargeable batteries commonly used in high-performance flashlights, digital cameras, and other electronic devices.
The name “16340” refers to the battery’s dimensions: it is cylindrical in shape with a diameter of approximately 16 mm and a length of about 34 mm. It has a nominal voltage of 3.7 volts and a capacity ranging from around 650 mAh to 1200 mAh, depending on the specific model.
16340 batteries are rechargeable, which makes them a popular alternative to non-rechargeable CR123A batteries. They are known for their high energy density, which means they can provide a lot of power in a small package. They are also generally safe and reliable, but like all lithium-ion batteries, they can be dangerous if improperly handled.
It’s important to note that 16340 batteries may not be interchangeable with other batteries, even if they are the same size and shape. Always check the manufacturer’s instructions or consult a professional before using these batteries in your electronic devices.
