Exclamation LiPo deactivation process

I would add, that before disposing the batteries, you should deactivate them.
Usually it is done with a can of salty water.
  1. Prepare the glass jar or plastic container that you can submerge the whole battery inside.
  2. Fill it with water and solve a lot of salt (like 1 tea spoon on 1 liter of water).
  3. Carefully cut or unsolder the wires of the battery - one by one. Only the battery electrodes should stay. Don't forget to isolate them with the tape to prevent accidental short.
  4. Submerge the battery into the prepared salty water and keep it outside of the house (as it will produce gases) for 24 hours. Make sure it stays on inflammable surface and can't short circuit with the walls of the container (can)
  5. When there is no more reaction (bubbles coming from the battery) the battery (with the water and most likely the the container) can be disposed.
This is done to prevent accidental fire. The electricity left in the battery will cause electrolyze process in the salty water and will dissolve one of the electrodes (so there will be nothing to short circuit) also it will completely drain the battery to zero and probably (not sure) salty water will react with lithium deactivating it.
