No. First of all, the vast majority of 18650 batteries for sale online are counterfeit. They are not interchangeable with anything, and are a major fire risk.
Are 18650 batteries used in laptops?
Now, before you start tearing things apart, note that the lithium cells in a laptop battery can contain a lot of power, and you can hurt yourself or set things on fire if you’re not careful. These are lithium cells which go by the part number “18650” (this is usually printed on the side of the cell, in fact).
Can I use a different battery for my laptop?
Laptops don’t share a common battery size and shape. So, although you cannot swap batteries with another laptop user (unless they have exactly the same kind of battery), you can buy your laptop a second battery and use the battery to prolong battery life.
Can battery brands be mixed?
A: As chemistries and voltage vary across both battery types and brands, we recommend that you do not mix batteries. Mixing of cells can result in battery leakage and sub-optimal device performance.
Why is it bad to leave your laptop plugged in?
While leaving your laptop plugged in constantly is not detrimental to its health, excess heat will definitely damage a battery over time. Higher levels of heat are most commonly produced when you are running processor-intensive applications like games or when you have many programs open simultaneously.
How many cells are in an 18650 laptop battery?

What happens if you over discharge an 18650 battery?
This is important, since the 18650 will be damaged if over-discharged, which is again a Bad Thing. It’s worth noting that there are “protected” lithium cells out there that include a small circuit on the top to do the same thing as the flashlight circuitry– i.e. to stop current flow if the battery voltage drops too low.
What to do with an old laptop battery?
At this point, your choices are to buy a new replacement pack, or put on your hardware hacking hat and safety glasses, and start taking things apart.

What should I do after replacing my battery pack?
Testing your cells first is a good way to weed out any duds. 5) Your battery pack may not work after you have replaced the cells. The cure is usually simple: apply a charge voltage to the end terminals on the pack connector.
