A trick to rejuvenate a car battery

In this video I show how I get some extra life out of an old car battery. This trick only works about half the time. This video is not about a load test. This video is just to show the rejuvenate trick.
1- The waste from this project went to the local recycling center.
2- I am wearing glasses in this video but most of the time I also have an extra set of goggles on ( that,s why I asked where are my glasses in one part of the video )
3- It is better to purchase a new battery. This video is only to show what can be done, it is not saying you should do this.
4- I never intended to use this battery after making this video, but I left it in the truck for about a half year before purchasing a new one, but I had planned to buy a new one from the start.
