Old laptop dead batteries making alive with simple techniques don't throw away your dead batteries
Old dead batteries can be repaired don't throw it away!! Just watch the video till the end and repair your 18650 dead cells.
This is the video about to repair the batteries those batteries don't have any voltages try it out with full precautions and safety measurements in the first hand. I'm not saying that in the video you have to do nailing in the healthy batteries, if the voltage is full you should care about it, lithium batteries are dangerous everybody know that, if you you are in field doing diy and batteries things, so make sure to do it in safe environment, do not try it with if you haven't any experience about the lithium batteries, and remember that in the video I showed the nailing the batteries but that's not the that just replica of the doing things easier than we thought, it can be repaired with the using others simple tools. So make sure it's not for immatures. Do it with full safety.
