I am seeking for a software that will allow me to determine the qualities of lithium ion batteries connected to a USB port of my computer, such as mobile battery banks, vape-mod batteries, rechargeable flashlights, cell phones and mp3 players etc.
The idea is to see if an ipod battery is able to retain a useful charge or if a vape pen battery is dead for good etc.

  • Most devices will not communicate their charge over USB. And if they do they will do so within their own custom software. So short answer: there will be no general software for this. – Thomas May 11 '19 at 22:53
