Buy an 18650 Tesla battery like in car?

Would like to buy a Tesla 18650 battery that is used in Model S.

Is this possible?

I could show people the batteries that power Model S.

Do these batteries fit an LED flashlight?

    Several of our EV Club members have these batteries for show. I went to Batteries Plus and bought one.

    You can get them on Amazon.
    Do a search and it will show some products they fit (like flashlights)

    Radio Shack has them.

    Good for show, the cells are a bit longer and wider than the common AA cell. The actual automotive battery cell Tesla uses is not for sale. Batteries that are the same cell size are available. A 18660 cell just describes the size (18 mm diameter, 65 mm long), but not the construction or chemical composition. Even Panasonic, the maker of the cells, does not sell Tesla's unique cell to anyone else.

    18660 -> 18650

    They are what Makita uses in all 18-volt packs for its rechargeable tools. I have a bunch of the Makits tools and batteries, some are aging, so opened one up and found they are the same Panasonic 18650 format in our cars. The packs open up using a torx screwdriver, but the cells, while visible, remain trapped in a glued-together internal plastic frame, which I opened with a Drexel cutting wheel. I keep a couple in the car to show curious people - one of 7,104 in every 85 or 90 pack.

    Why does tesla use so many tiny tiny batteries. It seems like the more individual batteries, the more weight is taken up by the batteries case.

    If they had half as many batteries that were twice as large, wouldn't you have less surface area taken by the battery case and thus the car batteries would take up less space and weigh less?

    codymail--there are advantages to having space around the batteries, to allow for coolant to circulate, and to mitigate failure if a cell goes bad. The Boeing 787 Dreamliner has a proprietary very densely packed Li battery pack which has catastrophically failed early on. No room for error, no space for cooling of containing a bad cell. Google it for more background...

    Their optimal size seems to be 20700 based on what the gigafactory is gearing up for.

    There is also a rechargeable flashlight that uses them.

    If you have a dead laptop battery, break the plastic case open - they are filled with 18650 batteries - anywhere from 4 to 12 batteries.

    They are very expensive at Batteries Plus. Cheapest is on Amazon or eBay (and you don't have to go someplace to buy them):

    Here a 2 pack for $6.34 with Prime shipping

    I think Tesla uses Panasonic batteries? Somebody can verify that - so if you want to be incredibly correct - here are two Panasonic cells:

    I have also seen 18650 batteries in big box home improvement stores for solar powered lights.

    They are the most common used battery in electric vapes as well

    I don't want to be too picky, but it would be nice to get one in bare metal without branding on it. On the Tesla factory tour they have an empty one they hand around that has "Tesla" laser-engraved on it. I can do that at the local hackerspace if I can find one that is just metal (I should be careful not to blow it up in the process <g>).

    Tesla was handing these out at their Detroit Auto Show booth:

    I drop the batteries around at singles bars...sophisticated women follow up. 'Nuf said.

    18650 is the same battery that my flashlight uses. VERY common.
    I took a pic, but I'm not sure how to embed it here.

    The same size, not the same internal formulation.

    I purchased one 18650 battery 3.5 years ago when my S arrived just so I could show the endless number of people that have asked me what powers my Tesla. They are always curious and amazed.
