Free "Dead" 18650 rechargeable batteries. Pls read description

fairly new (about 6 months) but i completely drained it and not charging anymore. i used a voltmeter and it shows less than 1 V. it could very well be dead. it's nameplate is 3.7 V and usually is 4 V full charge. lots of youtube videos showing instructions on how to revive these batteries but i wouldnt try it myself. if someone knows how it's safey done and bring these back to life, it's yours. posting this before i dispose. these are quite pricey batteries compared to the usual household batteries. disclaimer: do it at your own risk. and dont try it if you dont know how to do it safely. and i cant guarantee that these can be revived. i assume no responsibilities for any hazard it may pose.
