lithium cell model

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.
