- A way to re purpose your old bad 12v battery pack.
This really is not a complicated idea. Most newer cordless tools use lithium ion batteries. I now have the newer versions of this tool. The idea of buying more of the old type ni-cad batteries for some of my old tools seemed foolish so instead of trashing it I decided to try and recycle it. I use this one only when I do some work on my truck. I also converted one of my older drills to a solar tracker actuator. If you think its stupid or a waste do not do it. Simple.
I actually gave my cordless drill away to someone who was going to do this very same thing to it except with a cigarette lighter adapter for use with a jump pack,really a great idea.
This may work off a good 12V car battery charger. I think they put out enough amps to work without being overloaded. Also, the drill useage is not continuous which should keep the charger from over heating. This gives you a portable indoor power source from a source many fixit guys already have.Great idea even if you use batteries most of the time for when all your batteries run down on a job.
Enjoyed watching how neat and efficient your soldering technique is.
i legit thought you had an outlet cable soldiered up and were about to plug that into the wall for a moment.
sent ni-cad pack to get rebuilt last yr. cost 65$. Drill having battery issues again. will be doing this next. thanks, great job
Bugger, I new I was keeping 3 good 12v drills for a reason,I think I binned them. I was just waiting for a heavy 12v supply. And I found a 40A 13.8v PSU on an old car stereo display.
I have done this twice before, you do need a thick cable for this.I'm having a hard time finding anything on the net right now,but NiCad discharge current is about 6C,6 X Ah Capacity, so for a 3Ah thats around 18A,so a small cable will have loads of voltage drop.Hope that helps someone and not blow a fuse :D
Amazing.. batter of two worlds.
I dont undestand why industry don’t do it this.
it's all about squeezing out our wallets. we must agree he Macguyver'd it
Excelente vídeo thanks .I have a question.I got a black and decker drill 7.2 v that I had it running with my 12 v car battery ( for about 30 seconds) do you think 12 v would be too much power or it’s gonna be fine.I don’t wanna damage the battery or the drill.thanks
Very cool idea, you should put two dowels sticking out of the battery case so the alligator clips can have a place to stay put when not in use.
Cool! I've got a bunch of cordless tool missing batteries. Your approach is slick with the alligator clips. Thanks!
Better to make a low voltage extension cord that comes from a low voltage sorce to plug the drill into. But you may have to calculate voltage loss over distance.
Maybe your right. I changed the description from recycle to repurpose maybe folks felt mislead by the description. Thanks for commenting.
To plus it in to a wall socket you'd need a rectifier and step-down transformer. You could possibly use an Apple macbook charger although the amp draw might be too much. You would of course need a power supply to match the voltage of the tool.
Why not simply drill a little hole in the black half and just run the cable through with a knot tied on the inside ? That way you would never pull the solderings.
Koen Brouns I suggest about how to rebuilding batteries for cordless drills . I serach alot and i found a product I also found helpfull for used or reconditioned auto batteries is "Corbandy Battery Blueprint Crusher" - it will be on google if you need it
"cuz ur drill no work yet. ;)
A knot is kind of crude, they make nylon strain reliefs that install into standard sized holes, like you find on many consumer appliance housings. Grab them off of dead equipment before you throw it away, so you have some spares.
Nice job! Looks like a good idea to maybe make one of these with a longer cord for permanent use. Find a reasonable 12 volt smaller battery, like a lawnmower with the carry handle for convenience and just carry it around. It has to last sooooo much longer with a small battery. Only thing is you have to have a charger and you would be set with an awesome tool that you dont have to pay up to $40+ for all the time. A real battery should last for years, just like a car does. :) Peace
The persons leaving thumbs down are angry because they throw away their cordless tools!
Be Safe, Be Well,

wow i wish i had your soldering touch cool video
What would you use for the 18volt cordless tools?
You can actually use an old PSU to power drill with +12v line. So that you don't have to use any battery.
Your new, corded cordless drill, all your bits... And a riding lawnmower battery. Will all fit inside a cat litter bucket. Making your corded cordless, portable, again. The bonus here... Yes, even an 18v drill will work on the 12v battery. Maybe a bit slower. But with a LOT more torque and longevity. The riding mower battery has a ton more amperage than the cordless battery. So your drill will power through where it wouldn't before. Plus, it lasts a long long time. You can build a complete shed, with one of these, without ever having to recharge the battery. I know, because I did.
By the way, I didn't use alligator clips. I used a two prong trailer wiring connector. Connect one half to the battery, and leave it there. Connect the other half to the end of your cord. You can disconnect any time, and put the battery on a charger.
Good idea. Thanks for watching.

Yes this is the cheapest idea. I find another idea: replace the battery with cheap R/C LiPo battery. I bought 2200 mAh 2s 7,2V Lipo for my old Makita cordless drill. It cost me 9$ and i buy low voltage alarm for 2,5$ (to incrase the life of the LiPo). Maybe you need a charger if you havn't. Its cost about 20$. But it is cost with the charger less than the new battery. The other reason to buy R/C charger, it is balanced charger and the cordless LiPo drill chargers are not balanced. Which means the rc battery last longer than the original one.
Aceman307 great for off grid
Aceman307 They make attachments that let you use the new DeWalt batteries on the older tools don't trash everything
it worked for 18v dewalt but it doesn’t work for newer 20v. Any ideeas ?!
beautiful! but what if I want to use it inside my house? the wires won't reach the car.. can you help?
Great video..how about a dewalt corded cordless vacuum not working how to convert to home depot portable vacuum thank you have a blessed day and be blessed
Great idea for cordless grinders.They kill the batteries in minutes but if you hook them to a car battery with the engine running you can use them all day.
There are many ways you could do an 18 volt drill one way would be If you had a solar battery bank using 6 volt golf cart batteries you could tap off of three to get the 18 volts. The other ways would be more complicated but could be done. For me I never used the 18volt tools I figured if the work requires that much power I would use an a/c electric drill or tool. 12volt cordless tools work just fine for most work smaller and lighter weight. Thanks for the comment :)
Good practical application! Thanks for posting.
GOOD WORK. BUT - another challenge - how to plug into a socket and make it work?
good idea, saves binning an otherwise workable tool...thanks!
Thanks for watching.
Thats a good idea using a battery jump start pack.
Love this idea
Will do it
That's why I don't like battery operated tools inspite of it being handy to use, but once the battery is no longer produced, you'll be stuck with all useless tools!
Great idea, well explained, thanks
The drill will make a good backup tool when others fail. It's a shame to throw it out because of the dead battery.
fantastic idea time for lunch
You are better off using 12ga. instead of 14ga. not moving to even thinner 16 ga. wire. Remember that it may only be 12V but that works against you, means it needs that many MORE amps, and every volt you drop across the cord is far more of a reduction in power than with higher voltage equipment. Granted you started out with 12.6V if the battery is fully charged, but your original "12V" batteries started out at closer to 14V fully charged, even though they quickly droop to near 12V under load.
My good man, excellent video!
nice trick. ..thanks for uploading the video
What about differences in voltage and amps from stock battery to car or other batterys?? is that going to mess somthing up? i would be afraid to hook it up to my truck battery especially if still connected to the vehicles terminals as well, but im no electrician.
you could plug it into a battery from a freight train, as long as it's around 12V it will work fine. The drill motor only pulls as many amps as it needs regardless of the battery capacity.
what if you connect directly to charger without battery?no need for car battery
ProLife Infinity wow I think that's a good idea does that work make it look like an extension cord or something
That's an idea they're hook it straight to the charger
dougjstl1 amps will be a big problem,does a charger have enough amps to run a drill?
From one battery to another battery?
Wow that's kind of a neat idea that's kind of cool I idea i think
I like this idea I think that it would be cool to be able to use to alligator clips wall power and use a battery it would make all battery powered tool way more versatile.
I cant believe the drill companies have not made a corded 120 volt adapter for there drills.They could sell it for half the price of a new battery and people would still buy batteries. I don't think they would loss money.I cant tell you how many times I have used up all my batteries before the next one is charged.
yeah I would agree am going to gather up a set of 12 battery powered tools and build every thing I need
Aceman307 they do, you know all of them black boxes that you cordless phone and other things have, they plug in to 120 volt wall outlets and out put dc voltage, what you do is find one that is rated for your drill and connect it pretty much the same way but instead of hooking it up to a car battery you plug it in
Does it matter how big (amp hour) the external battery is? Should I put something on cable it to taper down the power? Thanks
As long as the battery is the rated voltage of the drill or a combination of batteries to get the correct voltage for your drill for example a 18volt drill you could use 3 6volt batteries or a 12 volt and a 6volt. As long as the voltage is correct it does not matter about the size. Thanks for the comment.
+The Cedar Workshop a load only draws the current it needs at its rated voltage. If that was not the case nothing electrical would work. A common wall outlet could potentially supply 20,000 amps of instantaneous current in some dead short circumstances. Before the wires in your wall exploded, or your circuit breaker tripped. But we can safely plug a nitelite into an outlet with nothing bad happening. Because it only draws the current it needs. Plug in a paperclip though and that will leave a black mark. While it draws the 1.21 GigaWatts it needs to transport back to the future.
I have that same problem for a number of tools, but the problem these days is that most tools are 18v, not 12v. Using a transformer is difficult, as these tools pull a *lot* of amps. Batteries are 12v, so some creativity is needed for the 18v tools.
me too, hope some genius make heck.;)
It's not that difficult. Car battery charger outputs 14.4V or so but more importantly can have enough current capacity to not droop under load. So much so that you might want to add a thermal sensor in the drill (if your model doens't have one), because using a battery pack the pack itself will limit the peak temperature the tool could reach, while with an infinite power source you increase the risk of damaging the motor.
However, if you treat your Dewalt well it should last for a very long time, is probably worth buying a new battery for unless you have plans to soon upgrade to a larger set of Li-Ion powered tools.
Just REpack them.
it's not that expensive.
18V NiMh REpack $15
18V Li ion REpack $25
Not everyone lives in places they can get replacements. Or the country they live in has very high taxes or import fees. These videos are not just for people that live in the U.S.
Usually a person who lives in a country where they can get a cordless drill, can also get batteries. Some people may think an old drill is not worth the expense of a battery pack, but if it was good enough to bother with the mod in the video, it was good enough for a new or rebuilt battery.
One thing I did when I rebuilt mine was take the drill cover off and scrub the grime away. It didn't look new afterwards but a lot better and I cleaned some dust and wood chips out of the air passages too which should help keep the motor cooler.
On the other hand, they look like they might have been NiCd battery packs and many people today opt to get a Li-Ion kit for higher capacity, capacity to weight ratio, and longer charge retention sitting on a shelf. I have to practically recharge my Dewalt NiCd drill before every use and that's with a rebuilt battery pack, though the rebuilt pack gained 800mAh capacity over the original.
That good idea, thank for sharing...
Thank you.
You should fix it to where you plug it into your cigarette lighter and have a lot longer cord for it
3.4 swapped 2nd gen!
subed!
wouldnt you techically be able to conect the clips to the charger?
The charger will not put out the amps to run the drill at full power.
Having said that, the voltage drop might be useful for a 10.8volt drill. I will let someone else do the ohms law ;P
Hello, i was at lowes yesterday and saw extension cables with a normal 3 prong plug in one end, and open wires on the other, i do believe it had a picture of tools... would this cable work to attach to my tool?
That sounds like a regular 110volt A/C plug that would work to fix a drill that already has that type of plug. In construction allot of times the cords get damaged and what you are describing is to replace a bad cord. This would not work for what I have done in this video because it works on 12 volts D/C like the battery in your car. I hope this helps.
No, buy a cheap set of jumper cables and cut the clamps off one end.
Thats a good idea fast and cheap.
GREAT IDEA
Reall cool solution!
OK.....
what would it take to add a regular plug that you can plug into any outlet in your home?
Thats harder to do you would need a transformer that could put out the amps needed to run this. Most of the transformers only put out 12volts at 1 amp or so.
The voltage at the wall outlet is 110 V AC. It needs to be converted down to 12 V DC. Otherwise, poof goes your drill and sparks will fly.
That's what I did. Use a laptop charger. They can provide 19.5v@3-5amps, which is perfect for a standard 18v drill. Fit the adapter inside the battery case, leave 1 foot of cable for hooking up to an extension.
trickle up that's only 100 watts. how's the power?
Connected it straight to the charger
find some old laptop battery, or buy new ones from old models, make some li-on packs. works great;
Bad idea. You still need a safe way to charge them, the original NiCd charger won't do it safely and the cells are different dimensions so you probably won't be able to fit the right # of cells in the pack plus the needed battery controller board.
Better to just buy a professionally designed and tested new Li-Ion drill with a battery and charger included if you want one Li-Ion powered, not risk a fire from some old laptop battery.
Additionally, laptop batteries are economized to provide Ah capacity at the expense of current, are not rated high enough for good power tool performance.
@@stinkycheese804 Laptop batteries are 18650 Lithium, the exact same as most power tools. Ten 18650 cells in a parallel/series configuration are what most power tools use. The charger circuit board can be purchased online for less than $3 and charges all cells equally.
can you plug it in a wall socket?
Nope...that would burn the drill up. You would need a transformer to do that.
smart and cool
Dang! I've been thinking about just such a solution for my remote cabin. In your video you attached to a car battery, so I assume your drill must be a 12 Volt type. What would you suggest for an 18 Volt system?
Yes my drill is a 12 volt type. You could use three 6 volt battery's in series and a 6 volt charger.
Thanks, much appreciated!
18v ok on 12v battery, you will get slight lower full opperation speed. You should also put a 30am blade fuse in as cloase as poiiable to the barrtery.
Thanks for the tip re: adding a fuse to the system. I'll give it a try.
18 volt batteries actually charge up to 19.5 volts, and the drills draw around 3 amps, which just so happens to match most HP laptop chargers.
why not connect directly to charger?
ProLife Infinity Your drill needs more amps to run strong. The charger does not put out that much power.
Then you might think about getting a beefier charger, because the gauge of wire itself that you used would be the bottleneck for a good charger.
@@Aceman307 why?!
The 12v charger can give a current up to 1.5A which is good and normal for the 12v drill/impact
Would I be able to wire it to a regular plug in 120
not directly, you will need a power supply of sufficient voltage and amperage so the 120AC is rectified and transformed to a dc voltage that works for your drill.
@@brentsido8822 so basically the original dc charger?
@@chrisrosenkreuz23 I guess that's possible if the original charger puts out enough current but as it chargers that battery overtime unlikely the output is enough to drive the drill under heavy load.
@@brentsido8822 thank you for the reply, that makes sense!
@@chrisrosenkreuz23 sure, welcome
Use a longer cord and connect directly to a 12 volt 25+ watt solar panel and use your drill (or whatever) anywhere as long as the panel can be placed in direct sunlight.
Dave Bainard the output would very a lot based on clouds and shade so you wouldn't get a consistent power output out of the tool
Now make it plug into the wall
You could stick a trafo in the pack, and run it on main power.
John Obmar ....you could stick a transformer in the pack , but then you would have to get 4 diodes and and build a full wave bridge rectifier (or get a silicon controlled rectifier) to convert the alternating current to direct !!!!!
Erik Vonderlieth
erik vonderlieth
There are transformers with enough capacity you can put in directly.
I would use an old adaptor for this.
John Obmar look to see its a "DC" direct current adaptor ....check the writing on it , look at output voltage , should say "DC" or "VDC"
(Erik)
@@BluesBoy-ij2rb bro the transformer already gives DC because it has rectifier
sweet
Do you use your Drill as a Sledge Hammer? You wouldn't be borrowing my shit, that's for sure mate.
How much volt the drull
12volts
Thanks
genius
Thanks for watching
well its not cordless, but good job!!!
Makes sense, I'm surprised you cannot buy a commercial product that allows you to run your power tools off the car battery in emergencies.
+tuffduty along with the fact every brand uses a different connecter, it would probably infringe on patents the companies have on those connecters.
+Andrew B (IrishRebel92) but I bet the company do not own right the the plug am sure that is all out sourced would you not think so?
iwantosavemoney apple outsources the production of the iphone, but they still own it. Now if a company were to claim they have made an improvement on the connector, then they might avoid a lawsuit, but no one is going to risk it.
+Andrew B (IrishRebel92) that makes perfect since
Outsourcing production of components does not remove your rights to hold patents, BUT on the other hand it's hard to stop infringement when dozens of fake straw man chinese merchants sell infringing products. Bring a law suit against one and it just disappears to be replaced by another.
NICE
+George Fenrich thanks

going to do this this weekend!
👍👍👍👍👍👍👍👍👍👍👍👍
in can only imagine how many millions of NiCad power tools are thrown into landfills. what these powertool makers have done is an environmental disaster. shame on them. they take no responsibility. the one exception is hitachi. they included a fake battery pack that is actually corded so you can plug it in.

What is the reasoning here. Is it because you're DIYer and also broke? If you're using that tool to make a living and the tool isn't paying for itself, get a different living.
You are kidding right. That is a very ignorant comment.
I share your opinion. Sadly, ignorance happens ; -(
