A trick to rejuvenate a car battery

  • Loading...

  • 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.

    I've got a couple of batteries new I let go I shouldn't have and I really wanted to understand how to rejuvenate these batteries they're deep-cycle but I can't understand a damn word you're saying hardly you need to learn how to speak or something I know country accent is one thing but when you're making videos everybody needs to understand what you're saying

    OMG my friend i did it just like you taught us.I did twice as u did, such as i bought 3 gallon of distill water, i even use warm tap water to wash out most of the gunk.

    Basically i start by rinsing it out first with a gallon of distil water, then gallon hot tap water, then another. Gallon of distil water, then hot tap water.then i refilled it with new distill water when am satified that all of the gunk is out.

    I'd be more concerned about exposure to all that dissolved lead (lead poisoning is cumulative...) than the sulfuric acid.

    Dec 7, 1941 America was attacked by Japan and did lots of damage. Dec 7, 2019 the Democrats attacked America and the best President America ever had by trying to impeach him. We took care of Japan and now we must take care of the Democrats. We must turn every state RED by voting R on every thing. You must vote R if you have to craw to the polls to save America again. The Democrats have been trying to impeach Trump starting 19 minutes after he took office. They hate Trump and America and are using a pack of lies by the crooked left and the lying media to do it. Every one has benefited by Trump's policies,even those who hate him. Vote R no matter what. Thank you, Keep America Great.

    It will work for a while depending on how far gone the plates are. BTW: What you called grime when you poured the acid out of the battery is the used up plate material. So it is now 2019, how did the battery turn out over time?
