Is 14500 the same size as an AA battery?

Introduction Are 14500 and AA batteries the same size? Although 14500 batteries and AA batteries are both common dry cell batteries, their sizes are different. The 14500 battery is a

Is 14500 the same size as an AA battery?

Not the same.

Although 14500 batteries and AA batteries are common dry cell batteries, their sizes are different. The 14500 battery is a lithium-ion battery with a diameter of 14 mm and a length of approximately 50 mm, hence the name "14500". AA battery is an alkaline battery with a diameter of 11.6mm close to the electrode and a length of 42.5mm, which means its size is smaller than the 14500 battery.

The battery is one of the essential energy sources in modern electronic equipment. There are many types of batteries, and the most common include alkaline batteries, nickel-metal hydride batteries, lithium-ion batteries, etc.

Standard lithium battery specifications and sizes 0440 battery, battery 14500, 16340 battery, 18650 battery, 21700 battery, 26650 battery, etc. The parameters are detailed as follows:

1. 10440 Battery: The 10440 battery is a lithium battery with a diameter of 10mm and a height of 44mm.

2. 14500 battery: The 14500 battery is a lithium battery with a diameter of 14mm and a height50mm.

3. 16340 Battery: The 16340 battery is a lithium battery with a diameter of 16mm and a height of 34mm.

4. 18650 battery: The 18650 battery is a lithium battery with a diameter of 18 mm and a height of 65 mm.

5. 21700 Battery: The 21700 battery is a lithium battery with a diameter of 21mm and a height of 70mm.

6. 26650 Battery: The 26650 battery is a lithium battery with a diameter of 26mm and a height of 65mm, with a rated voltage of 3.2 volts and a rated capacity of 3200 mAh.

7. The capacity of 18650 lithium-ion battery ranges from 1000 mAh to 3000 mAh, but the technology is generally 1800 mAh to 2600 mA. If the capacity of the 18650 lithium-ion battery is too high, the cost will increase significantly. In addition, the 18650 lithium-ion battery with too high capacity in non-special areas is not of great importance.
