    just because you can get a voltage doesn’t mean that there is any storage
    in the battery. Just replace it or study how batteries work. They can’t
    live forever.

    Buy NEW batteries.

    Do they get useful again? getting a Battery to have a certaing voltage
    again is just a little part of the game. Can they deliver a current at this
    voltage is the more interesting question!

    Thanks Charlie Aguilar for showing us the process of fixing cordless tool
    batteries. This is a resourceful video that helps everyone do things their
    own, if not with the help of the solar panel installers/experts.

    i’ve seen a similar process done on old triode and pentode tubes. there is
    some kind of build up that gets knocked off and revitalises them as well.

    Good video, align the crystals is what your doing. Another method that
    worked for my DEWALT was 5 or 8 hours in the freezer. Process base is soft
    freeze the crystals, tap with rubber hammer. Goal is moving the crystals
    back to the + / – position. Also use of car battery recharger on jump
    setting will work. Touch/release. Do not over heat. You can do this again
    if not 95-100% charge. FIBER0PTIC

    Before you try all of this for the Ryobi One batteries, try an easier
    process. Put the battery in its charger and plug it in, then quickly plug
    and unplug it multiple times. Vary the amount of time you have it plugged
    and unplugged. Sometimes plug it back in really quickly, sometimes wait for
    the lights to go completely out. It might take about 50 times, but
    eventually the red light may come on, showing it’s charging.

  18. Dave Burrows says:

    Wouldn’t you want to test something before you made a video to teach others
    how to do it?

  19. paul xmw says:

    Realy didnt think this would work but it did i used a 24 volt 3 amp drill
    battery to revive the 12 volt 1.3 amp. Tested the 12 v battery before the
    fix mesured 2.3 volts after the fix it instantly jumped to 12 volt. then
    recharged it Thanks

    I just threw out 2 Milwaukee and 2 Ryobi batteries! bummer

  21. Robert Fraser says:

    To avoid the possibility of a battery exploding in your face you can always
    run the wires across the room and tap them on the source battery(s) from
    there.

  22. Richie Rich says:

    lol holy crap dude I just fix 4 batteries that havent worked in years. I
    have an easier trick for you. Instead of using clips and shrink wrap and 2
    18v batteries just use a 12v car charger and put it on engine start mode.
    Mine put out 15v and worked like a charm! Cool video!

  23. PettyMower says:

    I’ve tried this with a dead 18v DeWalt. I wired (2) “good” 18v batteries in
    series to get a total of approx. 36v, and followed this video’s
    instructions. The battery now works fine! Thanks a bunch!!!

  24. sonny Godly says:

    reverse polerity will fix the bad one in pack,,,should take bad one or 2
    out and do the process.would work better

  25. sonny Godly says:

    Yes that process works but the batter will not hold load for long,what u do
    is take the bad ones out of pack shock them in reverse,then charge them.

  26. I take pleasure in, cause I discovered just what I used to be taking
    a look for. You’ve ended my 4 day long hunt! God
    Bless you man. Have a nice day. Bye

  29. The other day, while I was at work, my cousin stole my apple ipad and tested to see iif it can survive a
    twenty five foot drop, just so she can be a youtube sensation. My iPad is
    now broken and she has 83 views. I know this is completely off topic but
    I had to sgare it with someone!

    of dirt. For example, if your teen had plans to meet with friends afterwards,
    she can go out after the room is organized and clean. There is
    a wide choice of vacuum cleaners on the market
    today of varying styles and designs.
