    What is 14500 Battery?

    What is 14500 Battery

    Generally, the 14500 is a lithium-ion cell battery with a cylindrical dimension of roughly 49.2mm in length and 13.5mm in diameter. In a word, 14500 is known as the AA rechargeable battery.

    Though the overall dimension of the 14500 is similar to the AA batteries, there is a clear distinction between them in terms of voltage, chemistry, and lifespan.

    AA has both rechargeable and Non-rechargeable batteries. But 14500 is a button-top terminal rechargeable battery with a usual voltage of 3.6V or 3.7V. In contrast, other AA rechargeable batteries have a nominal voltage is 1.2v.
