Lithium cells come in a wide variety of models, each with its own specific designation.
 Here are some common examples:

Common Shapes and Sizes

  • Cylindrical Cells (like AA or AAA batteries, but bigger):

    • 18650: 18mm in diameter, 65mm long. Common in laptops and flashlights.
    • 21700: 21mm in diameter, 70mm long. Used in electric cars and power tools.
    • 26650 & 32650: Even bigger cylinders, for things that need a lot of power.
  • Pouch Cells (flat and flexible):

    • Fit well in slim devices like smartphones and tablets.
  • Prismatic Cells (boxy):

    • Rectangular blocks are often used in electric cars and large battery packs.

What those extra numbers and letters mean

  • They give you more details about the cell's performance, like how much energy it can store and how quickly it can release. For example, in "18650-30Q", the "30Q" tells you about its discharge rate.

Finding the right battery

  • Always check the manufacturer's information for the most accurate details about a specific lithium cell model.
