found an old vid we did >10y ago.

we manipulated a single 18650 cell to bypass various safety mechanisms and overcharged it in a safety cage.

this is about the same energy and and energy density your phone has.

the size of the cell is a bit larger than your thumb.

a samsung INR18650-29E

Wenn 1,95Ah drin sind schreibt man 2,4Ah drauf.

Steht schon so in der Mao-Bibel.

Got a new toy - 18650 battery tester, so checking if my spare batteries are up to specs.

Also testing 3 Samsung cells that I found inside of my accidentally burned Goal Zero Venture 30 power bank - while I’m waiting for a replacement IC to arrive why not check if the batteries should be replaced as well 🤷🏻‍♂️.

Love the fact that I can just plug in any 4 batteries into this tester and see what they’re capable of 👌🏻.

#Batteries question:

18650 #Lithium batteries are often described with the chemistry type as e.g. ICR, IMR, IFR where the cathode is generally the middle of the three letters.

I have some *ISR* #18650s which I may have to replace.  I haven’t found a detailed reference.

(The cells are available internationally but possibly not inUK and there may be a reason?)

I know there’s a Lithium/Sulphur battery type but it’s new; these are 5+ years old.

Any ideas what the S could be?

I finally bought an 18650 charger, something I've been planning for a long time
