    Default Tool Battery Rebuilding

    I am going to try to rebuild some of my tool batteries.

    Anyone have any first hand experience with doing
    this???

    The savings aren't huge but you can bump up the
    amp hours as well as insure quality cells.

    Never done it, have considered it, my nature is to fix stuff instead of investing in new. Do you have a good (quality and cheap) source of Sub -Cs? Also, are you going to get Sub-Cs with solder tabs?

    I have a bunch of old/dying power packs - like to get them running again.

    After digging a lot I found the guy on ebay to be
    the best source for Sub C batteries for price and
    quality. He has a web site as well but they sell for
    more money there than on ebay (go figure).

    Rechargeable batteries are only made by 2 companies
    in the world. Panasonic and Sanyo. So no matter what
    the label says, they are one of those.

    I am leaning toward the 3800 mAH instead of 4500 mAH
    because they are a better value and will blow stock
    batteries out of the water, even my new 3.5 packs.

    And yes to tabs. This guy will not combine shipping so
    even if he ships them together you pay full load. But
    I can't find a better source even with that..

    Not super cheap........... but a 20 pack of matched cells will
    rebuilt 2 of my 12V packs ($30 a piece w/S&H).

    All you need is a good soldering iron (500W), some rosiin core
    solder, and a scuff pad to clean the tops before soldering.

    Use the old battery case to hold the batteries in position while
    soldering.

    There was a guy selling instruction son how to rejuvenate your old tool batteries by zappingthem with a power source using jumpers. He claims it works.

    ....sounds like my father's friend who was always mentioned when using heavy tools named "four finger harry" (he was imaginary). i assume the person you are talking about has a similar name, but referencing his acid burned face

    NiCad's can be rehabilitated due to "memory". Not sure
    if I'd try that method

    I have switched over to NiMH over the years and if I was
    rich and famous I'd do lithium ion's. But NiMH is so very
    much better than NiCad's

    How are you disposing of your spent power cells?

    I just throw them in the trash, along with the burned-out fluorescent tubes and old, half-full pesticide spray bottles. Just kidding, no I don't.

    The big box home improvement stores have bins for just that purpose - disposing of used dry cells. I have to pay a buck to dispose of the fluorescent tubes, but it is worth it - mercury is a nasty poison, especially when it ends up in groundwater and my can of tuna. We have a couple days set aside in the spring when you can bring in old paint cans, pesticides, lead batteries, etc. for proper disposal by the county.

    Same as you........... I hope.

    No batteries should go in the trash, especially Ni Cad.
    Nowadays there are battery disposal stations within
    easy reach and there is no excuse for tossing even
    alkaline batteries.

    I have rebuilt batteries for power tools and such. Not to hard unless the batteries are tacked welded together. Then it is best to get batteries with tabs. Check to see if there is a BatteriesPlus where you live. The will rebuild for a nominal fee and their batteries are affordable.

    I have rebuilt lithion notebook batteries before and have a few links for batteries.

    If you want to change your tool over to lithium you need to get the controller board also. That in my opion is too much trouble.

    I am perfectly happy with NiMH batteries and their
    performance.

    Picked up 4 "dead" battery packs last week on ebay.
    One turned out to be a newer on and in great shape!!
    I have to order the sub-c cells next week and run
    down a decent soldering iron. I only have a pistol
    type and a 25W pencil style. I have read a 60W pencil
    style is best for batteries???

    I have a heavy duty pencil tip that with digital heat control (I used to do some SMT soldering before I discovered the "bake in the oven approach") and I've used it to put together many battery packs. Most of mine have scars where I've opened sealed plastic housing but they still work fine. It's a great way to avoid the high price of new battery packs.

    I'm sure it's still used for something somewhere, but most of the time someone is paying abatement fees for it.

    Keep it sealed if you don't know what it's capable of. The term "Mad Hatter" came from it's use in the tanning industry in England way back when. The vapor it releases is as bad as contact with it.

    Agreed. It is bad stuff. I had to find a home for a whole bunch of mercury once and was lucky to find a university that took it.

    I need it. I have been working on building a mercury vacuum pump for some time. I only have a quarter of the amount I need.

    Yes, yes I know the hazards.

    OK OK, I give up! What do you need to pull a vacuum like that for

    Well my son and I are going to experiment with making light bulbs, geisler tubes, and early tube diodes.
