What are the different lithium battery sizes?
What are the different lithium battery sizes?
For Li-ion rechargeable batteries, the most common sizes are the 18650 (18mm diameter, 65mm length), the 26650 (26mm diameter, 65mm length), and the 21700 (21mm diameter, 70mm length). Cylinders are symmetrical, have a robust mechanical form, and can be efficiently packed.
Are lithium batteries all the same size?
Lithium-ion cells have since become the standard in most tools and larger applications where their smaller size, lower weight and higher capacity greatly improve utility. Not all lithium-ion cells are the same, though; there exist different variations of anodes, cathodes, storage configurations, and chemistries.

What is the difference between 18650 and 21700?
21700 vs 18650: What do the Numbers Mean? 21700, 18650, 20700 and others simply refer to the physical size of the lithium-ion cell. For 18650, it’s an 18 mm diameter x 65 mm length. 21700 is 21 mm x 70 mm.
How do I know what size lithium ion battery I have?
Lithium-ion cell sizes The most common lithium-ion cell is the 18650 (the numbers define the physical dimensions and shape as follows: 18mm in diameter, 65mm long and the 0 means it has a round cross-section) which is due to its widespread use in laptop battery packs.
How do you measure a lithium battery?
• Multiply the Ah by 0.3 gm to determine the amount of Lithium in each cell:
- 2.5 x 0.3 gm = 0.75 grams of lithium in each cell. • Multiply the amount of lithium in each cell by the number of cells in each battery:
- 0.75 grams/cell x 6 = 4.5 grams of lithium in the battery.
- 11.1 V x 4.4 Ah = 48.8 Wh.
Are CR2032 and CR2025 batteries interchangeable?
For as long as either fits in the battery compartment, the CR2025 and CR2032 may be used interchangeably with minimal effect although the CR2032 would probably last slightly longer simply because it has a higher capacity (mAh).
What is the difference between a group 24 and a group 27 battery?
If you compare a group 24 battery and group 27 deep cycle battery together, you’ll notice that the mp hours are slightly higher on the group-27 product. This specification difference is made on purpose by the manufacturers. In general, a group size with a higher number has more amp hours than lower values.
Is C battery bigger than D?
C Batteries Size C-sized batteries are smaller than D batteries but larger than AA and AAA batteries. They are: 50mm or 1.97 inches in length. 26.2mm or 1.03 inches in diameter.
