All things you need know about 16650 battery

All things you need know about 16650 battery – Li-ion battery technology has evolved so rapidly that it can sometimes be difficult to keep track of all the different sizes. Well, if you look closely at the list, you’ll be surprised to know how many types of lithium-ion batteries there are. Battery types fall into a variety of different categories, ranging from shapes and sizes to purpose of use.

This article details the 16650 battery and its corresponding features. So, let’s get started.


What is 16650 battery?

16650 battery is a lithium-ion battery of the cylindrical type. The 16650 batteries are best used for large power tools, electric vehicles, electric bikes, drones, power tools, LED lights, and other equipment that requires a high power output and heavy currents.

It can be recharged up to 800 times with proper use before its electrical capacity deteriorates enough to become unusable or unsafe for its intended application.


How does 16650 battery work?

Like other batteries, the 16650 battery consists of an anode, cathode, separator, electrolyte, and two current collectors (positive and negative). The anode and cathode store lithium. The electrolyte brings positively charged lithium ions from the anode to the cathode and vice versa, through the separator. The movement of lithium ions generates free electrons in the anode, which in turn generate an electric charge at the positive current collector. The current then flows from the current collector to the negative current collector through the device being powered (cell phone, computer, etc.). The separator blocks the flow of electrons inside the battery.


As the battery discharges and supplies current, the anode releases lithium ions to the cathode, creating a flow of electrons from side to side. When plugging in the device, the opposite happens: Lithium ions are released by the cathode and received by the anode.

How long does 16650 battery last?

Usually the cycle times of 16650 batteries is 800~1000 times, which means that if you charge and discharge once a day, then the lifespan is 1000/365*2=2.74 years. If it is charged and discharged every two days, then the lifespan is 1000/365*2=5.58 years.

What is the difference between 16650 battery and 18650 battery?

16650 batteries are rechargeable, non-spillable, and have a same height with 18650 batteries. 16650 batteries are most often used in digital cameras, but they can also be used in video cameras and other devices. What is the difference between both?

Actualy the 18650 battery and the 16650 battery use the same chemical materials, both belong to lithium-ion batteries. . The same goes for battery voltage, the only difference is size and capacity. The naming of the battery is based on the size of the battery. So you can also intuitively understand the 18650 battery and the 16650 battery. When you see the number 18650, “18” is the diameter and “65” is the length. The 16650 designation of the battery type is 16 in diameter and 65 in length.

How to prolong the lifespan of 16650 batteries?

Using Tips

  • Avoid completely draining the battery
  • Charge the battery as soon as the battery indicator shows that the battery is low.
  • After the battery is used up, please charge the battery in time.

Maintenance Tips

The purpose of routine maintenance is to place the lithium battery in a suitable environment, thereby delaying the aging of the battery.

Here are two maintenance tips we need to follow.

  • Moisture proof.
  • And avoid direct sunlight.
