18650 batteries have gone absolute dead short
I have 2 18650 batteries for a vacuum cleaner, and they wouldn't charge. I took it apart and tested the cells, and 2 of them were completely dead, not even microvolts. I tested their resistance, it was 2Ω for one and 3Ω for the other. Idk what happened, if they over discharged or what, but not good.
Good side is: Yay! 4 more 18650 batteries for my collection!
P.S. Is there really a nothing phone???
