Repair/Revive/Recondition cordless tool batteries






How to recondition your cordless tool battery yourself.

20 comments:

  1. can I offer a suggestion? Invest in a digital charger for lithium R/C
    batteries, they can charge ANYTHING, and they will recondition nicad packs
    by pulse charging them, and they can be programmed to discharge/charge
    cycle multiple times. My first one was less than $30 and could do up to 6S
    lithium, or 24v nickel or lead batteries, and from 12vdc input- it was
    meant to be run from a car's battery in the field.

  5. Hey love your videos but I found a better way just plug and unplug you
    charger until the light trips into the red to zap the charge.

  6. Ok Paul I have two 18 volt craftsman this appears to be notorious after
    sitting for a time.My question is I have a good 15 Nicad and a new 22 volt
    Nicad is this enough to jump these . If it isn't can I use mixed volt sizes
    to equal 30 volts?

  9. Hi Paul, what would I use to revive a 14.4v battery? How many volts do I
    need? I have 2 of these and they both don't hold charge.

  10. If you need to totally rebuild your batteries, I saw a video by
    sixtyfiveford and he shows how to do it yourself. he explains it very well.

  11. Hey Al, Thanks for the comment! I hope you are doing well with your Vline
    clamp, it is an Awesome Tool and I am hoping to see it in the major stores.

  12. hi paul, I was able to revive 4 of 6 old 18V Ryobi batteries with this
    method. very happy. my question is when I put my tester on them to check
    the full charge voltage 2 of them test at 19.something and stays there (the
    reading on the tester) but on the other 2 when I test them they jump up to
    19v but then reverts back to 1. what does that mean for those 2? why wont
    the voltage hold (on tester)? also what make is that tool, angle impact,
    never seen one? thx keith

  13. Keith Davison (continued) The angle impact is made by Ridgid, (Home Depot
    Brand). Although the tool is great, the nicad batteries are JUNK! When I
    bought this impact drill, the original battery provided very little usage.
    I then bought a their heavy duty battery as a back up. Both batteries
    developed a memory after sitting on my shelf for a couple of months. They
    still will not hold a good charge and Ridgid no longer sells the nicad
    replacements. I guess I will rebuild the batteries!

  14. Hi astrodog, I would not recommend using lithium ion batteries in any way
    with this procedure. I was told that it can be dangerous. Besides it is not
    worth taking the chance. Sorry! Paul

  15. thx paul, ya I seen a couple videos, I guess I will start by taking them
    apart and test each cell. keith

  16. can you use lithium batteries as the power source to zap a Ni Cad?

    ReplyDelete
  17. Hey Keith, It looks as though 2 of your batteries have bad cells. Your
    Nicad batteries have multiple small batteries that are hooked to each other
    in order to provide a higher voltage. If one of those batteries goes
    completely bad, it will not hold a charge. This only works when the
    batteries have developed a bad memory. Usually from sitting up without
    using them often enough. They have a couple of sites on youtube that fully
    explain how to replace a bad cell. Continue--------------------------

  18. Hi CDNE, NO!!! You cannot zap lithium ion batteries at all, they can
    explode. Sorry! Paul
