- So I've used this method a few times probably 25 times actually to jump start my truck which is a V8 with a completely dead battery and also my wife's car who has a bad battery so her battery is always dead just a nice little trick to get you out of a pinch
Hi, this video could have possibly saved my life. This might be a bit of an exaggeration as I would have survived 1 way or another but I was in a remote part of Australia with no phone reception for 100kms, to get out of this nature reserve for help would have been a 11hr walk (all flat ground). I brought by DeWalt torch & 5AH battery with me for the camp and just before I left, subconsciously I grabbed a bundle of thin cable, didn't know why I just grabbed it. Anyway, got back to my car and I accidentally left my lights for half the day, my battery was FLAT. Anyway used the thin cable, jammed it into the battery terminal, stripped a large amount and bolted onto terminals burning my hand in the process, started the car and it started instantly! If it wasn't for this video I would of had to do the huge walk to the main road in 35 degree C weather.
Excellent!
Well that's on you for being a dumbass going an 11-hour walk away without (consciously) taking any precautions.
O.M.G. I have been stranded in the woods for 4 hours with a dead jump box . So I googled why my jump box is dead. I found this video. I used the smallest battery dewalt makes and as soon as I hooked it up I could tell it would work . And first try started right up. V8 and its 33 degree . THANK YOU BRO VERY COOL TRICK
Amazing how resourceful we become. Awesome!👍👍👍
Great I'm glad it helped you out. Best of luck in your future travels...

power of phones RUclips and dewalt
I’m going to use this for sure thanks for the video
It was about 3am. I was in my car listening to music. I suddenly remembered that I hadn't started my car in awhile, turned the key and all I got was a few clicks.. I didn't know what I was going to do. I don't know what I expected to find on RUclips but I didn't have any other options. I drive with a decent tool collection that includes a DeWalt drill, yes with the smallest battery. I had speaker wire. Armed with that and this video I felt... Hopeless, and swore I'd never tell anyone that I fell for this lol.. I connected it, got in my car and turned the key.. I couldn't stop laughing it was AWESOME! It worked and there is no way it was going to start without a jump. I didn't know what to say. But I do now.. THANK YOU
Pppp

Dude! I almost bought one of those boxes that jump start your car the other day, glad I didn't because I almost always have 5 milwaukee batteries with me. Thanks for the tip.
Have you tried it with your milwaukee battery yet ? I have milwaukee tools and no dewalt.
@@ernestwalden3894 I did and it worked, although I think it's bad for the milwaukee battery to drain that fast and I've read that it's risky to use 18v to jump your car, but I didn't have any problems. It's definitely a good trick to use if there's no other option. I bought a halo thing now though.
@@ernestwalden3894 i did it with a Milwaukee battery today that was only half charged worked sweet saved my ass
@@colepeterson9961 your batteries should have circuitry that should protect them for draining to fast or.too low. Plus likely no more drain than when you get a large drill bit stuck and stall your drill
@@grisby6484 It does but it only tells the drill to switch off, it can't tell the car battery to switch off so can still over drain the drill battery in this scenario.
LOVE IT! Great tip! Way to think outside the box! Thanks bud.
I had to setup my nimh dewalt battery to jumpstart my Toyota hilux 3.4 litre v6 . Works like a charm but draws 30 amp. Set it up about 6 years ago and couple years later those jumpstarter units were everywhere. Nice job.😊
Genius! Jump cables and 2 metal forks and worked brilliantly lol
Great video. Can't stand premade videos. People need to see the real issues when fixing things.love your video good trick
Dude, you literally saved my ass. Thank you so much! I had no idea! Bloody brilliant!
Thank you for not cutting/splicing the video. When I first clicked to watch this I rolled my eyes to myself because I figure most people would cut the video and charge the battery to make it look like it worked. I have to try this tonight. The largest battery I have is 4AH, but if the battery's discharge rating is the same it should work quickly for me like it did for you.
My educated guess why it didnt work the first 2 times was because it wasnt a good connection(battery level meter 3 bars). As soon as a good connection was made, the voltage of the 20v and the dead car battery(guessing maybe 10 volts+/-) was reliably combined in parallel thus giving the battery level indicator a reading in the low to mid teens(+/-) which is why it suddenly read 1 bar. Thats why it finally started. The 3rd attempt was a more reliable connection.

Thanx for the cool video!
Totally correct. Many times the connections on the terminals don't make complete contact resulting in zero charge.
Dude this just started my van in below zero temperatures, thanks so much
thanks for the help! Great video and something really good to know. Good work, son!
This is great I already have to make this. I think I'm going to use a little beefier wire just to deliver the goods a little better. One thing I would suggest is if your cables are long enough set the DeWalt battery on the ground so that if it goes up in flames, your car doesn't get torched. If the cables are too short it would still help to set the DeWalt battery on the fender so that if it goes up in flames you can at least knock it off onto the ground. I know the odds are against that happening but these are Lithium-ion batteries were talking about so it definitely can happen. And I'm not saying don't do it I'm just saying put the battery where you can knock it on to the ground if something happens.
Also as far as those little connectors I tested some of the round ones that have a hole in the middle and they fit in there and give a fantastic connection. So if you have those give them a try. It's the type of connectors that are made where you attach a wire to it and it allows you to bolt the connector onto something. I think those do give a little more of a contact point.
It works because it takes time for large 12v car battery cells to pass power from 20v small battery cells. Car battery simply gets charged and that is why it took him 3rd time to jump start. If you live them connected for longer time then it might damage electronics but less likely because difference in cell capacity is huge and probably car battery won’t reach over 15v which is ok because that is about what it gets from alternator. However one needs to be careful because damage can be really costly.
I did the same with an 18 volt. Shoved 2, 16 penny nails in the battery and hooked standard jumper cables. Mechanic said it was impossible. He was wrong
That's how I did it!
Wish me luck I'm gonna fo it now
Good thinking
Nice!
Wow !!!! Awesome tip, A million thanks from Long Island .
This is very good to know. I always have 2 DeWalt batteries and 12 gauge wire on my truck since I do a lot of electrical work.
Thank you for this video you don't know how useful this is amazing video helped so many people already with this great idea
I found this out years ago and Yes it works!! I was stranded middle of winter with no one around for a jump. I took my 18V Dewalt NiCd battery and found the positive and negative. I took some 10 gauge stranded house wire (I'm an electrician) to get plenty of cranking Amps. Made my connections - it started right up! I closed my car doors, turned everything off (AC, radio, interior lights, headlights/park lights...) so the battery/starter can get full power. It worked!! I've boosted off a few other people in a jamb without using cables and they were AMAZED at how it did it!
In Extremely cold temp. this may not work. In this case, I Double up on jumper cables and connected in parallel to Increase the Power, more Amps. 2 Pairs of jumper cables connected the same way (the positives connected to positive and with negatives connected to negative.
I'm Not endorsing Anyone or Advising anyone to try this. Using jumper cables is the best and safest way to boost off your car. And always look away (or wear safety glasses) when making the connection. GREAT VIDEO!!
I used 12ga and it started right up. Wires weren't hot but I didn't have to leave it connected for more than 30 sec.
Insane it really works saved me from being stranded. I used a Bauer battery
This is crazy, that is One of the smartest things I've seen in a long time... You sir are genius good job
Must be around a lot of dumb sheeit 😂
Thanks I used a razor blade and a furniture wrench as make shift posts for my jumper cables to attach to. It started my V6 engine.
Really with dewalt battery well ? Video myb future?
@@isaacserna7593 yea sure thing bro
Should i use pennies or quarters?
@@Marcoulloa123 quarter might be more useful....more surface area.
I used pennies and it worked! Quarter wouldn’t fit
Awesome 👍 thanks for your effort making this video. Something new I learned.
Dude it worked!! Your video totally saved my ass. I thought maybe someone's has a trick on RUclips, sure enough. BAM! THANKS 👍
That was awsome! Just used it and it worked like a charm, saved my day, thank you so much.
Stole my first car today
How did that go for ya?
🤣 made my day
Did they steal it back? Some people can be selfish dicks.
Awesome, jail is right around the corner, you could be the pass around
@@Magnum-bh5no well lucky for me I’m not right around the corner I actually left from the corner which is where the car was located
Did this with my boat while in the middle of the lake. Only battery I had on there was for my 20 volt drill thought fuck it. Worked mint
Yeah cause why would you have a drill on a boat lmao 🤣
@@cummins-kk8mf why wouldn’t you have one?
@@cummins-kk8mf my curiosity said the same ting.lolol... but sometimes one does need to repair and engine on the fly
It works..just did it with my 18v Milwaukee battery.. thanks man
Just jumped my car with Bosch 18V awesome! Thanks for the video!
I tried this trick today and worked great, thanks Robert
Good video! Loved the mud.
Thanks for the video, my situation was a reversal, I used a car battery to Jumpstart a dead 20v lithium battery,with the car not running,so that the lithium battery will recognize enough current to charge the battery ,and get out the ( stuck)testing mode.
A really good trick,I done this but just want to say it killed the cells in my 18volt 5 amp battery. Loved the video . Kind regards Colin from croydon surrey England 👍 👏 👏 👏
Better if you unplug the dewalt after 2 min just so the battery have enough to start itself up
Dude, this works! The truck battery was so dead, the charger didn't even recognize it. I took an old jumper cable, jerry rigged it to a Dewalt battery... left it on for 3 minutes... and the charger then recognized it. Yahoo!!!!
Done This With My Dewalt 18v 2ah On Peugeot 1.6...Worked A Treat.....Great Post....Thanks.
Love these simple genius type tips. Thanks.
keep the top of your battery or in-between the terminals _clean!_ it's why the terminals are separated but when your battery is caked with dirt and oil those terminals are no longer separated and continue to short the battery - never would of thought of this *thank you*
that's cool. great idea in a pinch, I was just stuck for over two hours due to accidentally leaving my lights on. I do not think a drill battery would get my truck going just due to its size and the cranking amps required but I bet a couple of these in parallel would do the trick. a jumpstarter is like 80 bucks though and my drill batterys are over 100 each so id probably rather just get a jumpstarter to keep on hand just in case. I love the idea of something that can be used for multiple purposes though!!! I always have drill batterys around maybe ill build an apparatus that they can plug into and safely do this without risking the drill battery!!! million dollar idea!!
Hey thanks for checking out the video actually I drive a F250 Super Duty I have intentionally ran the battery dead all the way Dead with my headlights on just to see if I can get it started using this method and 1 20 volt battery will actually do it ..good stuff....
👍 I had the same idea
please consider this: a jumpstarter has a cable with protections, like a relay and 30sec timer included, or some large diodes. The diodes protect it if user connect battery leads the wrong way. With a drill battery you lack these safety features. If a drill battery catches fire on top of your car, how do you estinguish fire? Liion burns at very high temps, you need sand to stop the fire. It's very risky and easy to make mistake of connecting wrong way the wires. Even a short between leads can damage drill battery. Your bet is on internal protection in each battery cell, assuming there is any.
A jumpstarter does not charge car battery, it just sustains the initial high current draw while keeping voltage from dropping too low. Thus, the jumpstarter needs the car battery to have some juice left, they work together. I assume that if you start car with jumpstarter a few times, car battery level will drop lower, to a point where it won't start at all, even with jumpstarter attached.
The drill battery actually charges the car battery, getting the voltage a little higher, to a point where it can start the car. This should work if the car battery is not very deply discharged.
This is why you need to wait some time, to get it charged a bit. A car battery has high capacity, e.g. 70Ah at 12V, but it may no longer start car if it's at 65% charge. If you can get it to 75% charge, it starts car.
Success jump starting my volvo 940 turbo 2.3 , with my 4 Ah Dewalt battery took me 5 minutes .Thank You Very Much Friend God Bless You 🙏🙂
This saved me tonight. Worked with 18gage low voltage wire.
I have a 12 v
Will it jump start my car its fairly small
I love that you didn’t cut and paste the video thank you
I was stuck with a dead battery and was able to use my power tool battery (20 volt, 5ah), 2 pennies slid into the small battery and jumper cables hooked to them and the car. Worked instantly!
Holy sheep 💩! It worked?? What a trip. I never would have thought. That's why I miss manual transmissions "sometimes"
Dead battery, no problem.
Thank you great to know
Worked thanks brother for getting me home from work
Totally freakin work man and my friend brought me a jumper booster and that she didn't work literally took under 5 minutes it was completely dead to give an almost a full Boost of energy trying to crank on
New jumpbox from last Xmas a dud..used Dewalt 20v 3amp hr start first 09 silverado too..first try..thanks friend happy Thanksgiving
Good stuff man, it worked so good for me thank you
I'd smoke a Dewalt battery if I was stuck in the bush with a dead battery. Thanks!
Tank for this trick Man. I just jump start my 2012 hyunday accent my using the same method. In my case using a 20v lithium battery that is made to go on a mastercraft impact drill.
I found that to work for me when i was in a pinch. I never had to wait for it. it always worked right away for my chevy tahoe. I use romex because I usually have it laying around. Maybe that's why? Thank you for sharing
I've used a 4cell lipo that I have for an rc car. Worked great 👍
Damn didn’t even think of that, I got a 3S and going to try it rn
Just did this right now . Worked . Thank you
at 2:15 when you HEARD that spark, that tells you the dewalt battery and the car battery are now physically connected ... NO need to keep messing with the wires, let it sit for like 2-3 min ...
Rite on .....
Shut up
@@dchromej iili
I used to have my cable jumpers ,,but you know what one day l had a low power in my battery,and l was struggling because l forgot my cables in another car, but some how l remembered that l saw a video like this one and you know what l try with my maquita drill battery full charge,and it did work,thanks you save me,
LOL, I had those exact wires in my tool box
I’ve never jumped a car this way but I use a similar setup when going to the junk yard to test window motors and check mileage on the dash.
i gotta remember this
Hahahhaa me too...I repair car electric motors and sell on eBay and I use an old black and decker batter to test when I'm finished and I've used to diagnose motors in the car with it too... it's handy as heck 🙋
@@bilbobaggins4710
At my work, a few of the guys and me have little 12v UPS batteries. Work great and we recharge them with a regular NAPA battery charger.
But.....Ive used the crap out of my dewault batteries for the sane thing. Especially if Im not close to my tool box and of course before I got the UPS battery.
🤘
Muy bien... Saludos desde Ensenada Baja California México
Had a test lead.. probably way to thin ..wire smoked a bit but it fired right up .. thank you bro this helped me out of a jam
when the car is started, the altenator only makes around 14.5v so it shouldnt send current to your battery. likely your drill battery would still be charging the car battery. good video. ill be keeping a set of those cables in my truck now lol
thanks for the video, may become handy someday !
That’s good to know! Thank you!
thanks for the info. one for the little guy what guage wire did you use ??
nice trick. thanks for sharing the idea
Definitely works.😊👍👍👍👍
I just started my car this way and I can say it worked..
Lol it werked!!! Thank you so much 😁
This is crazy, got stuck out in the bush dead battery nobody around so googled some ideas. I had a Milwaukee battery and car started first kik. Thank you
Omg this is amazing.
I didnt have connectors like that. So I just slid TWO LARGE washers between each positive and negative terminal on my Dewalt battey and connected by booster cables directy to the washers. Worked first turn 😂
Did u tape them?
Can i use pennies or a quarter?
@@Marcoulloa123dime
Just used this trick to jump my lawn mower thanks!!
Good info my friend, Thank you. My Cummins 12 valve diesel has two batteries so I reckon no go for me.
I always keep a charged portable dewalt air compressor with me so I stashed a wire in the compartment of the compressor and now I have a car survival kit
Can't believe it started most newer cars detect over voltage which 20 volts is and will not start
Thanks.Good demo video.
Buy yourself a diode to inline it into your wire so you won’t get the back feed from your alternator next time.
It is 5S2P very strong. Thanks.
Haha you saved my ass from having to get a tow truck thanks man 👍
I had this Idea today. walking a few blocks home. sure enough youtube. it’s been done. I’ve always hooked up negative positive bla bla. to battery. I’ve read manuals on this. I know what it says. I follow the order of connections but have never had good results going to frame. Is this simply mostly as a precaution. And is it the distance from the battery- that radiates the energy of the connection out instead of directly on the terminal?
Just like welding?
Great video. If you put the Dewalt - end on a ground source you wouldn't have to worry about back charing your battery at that insane amperage.
Not sure if you said it,. But you made that cable? Just wondering before I cut my spare jumpers up to test it
Wow lots of views! I love it. Found this video from a loosely based Google search. I'm making my "jumper box" right now!
Awesome trick. I think if Use smaller gauge wires and make them shorter . It will work a bit faster
I just had to do this, this morning. Felt like MacGyver 🤣
So with the engine on it will charge the dewalt battery?
Wow wonderful I tried toy battery 12V 7 ah Al so working well
Probably more safe to be honest! 20v is alot of power....
So can u instantly charge the dewalt off car battery?
I've done this with a 2ah dewalt wire and vice grips
I put wron polarity on car battery, did i just burn out my dewalt battery??
Attention, do not imitate !!!!!
Too high currents are flowing!
There is a risk of fire and / or explosion!
A 1 ohm 400 watt resistor limits the current to 20 amps.
protect your health and your life!

LIFE SAVER THANK YOU!!
so was skeptical about the cars elec considering its a rental (2021 toyota corr) lol so i disconnected the battery from the car then with romex wire and a fresh 20v 4ah battery i connected it to the battery for literally 2 mins took it off reconnected the car and started with no issue ....
Great video 👍
I think the cables are trash or the connection isn’t good mine always dropped down to one bar when I hook up to a battery so your reading full bars on a dead battery is the problem I’m thinking
Yes you can jump start your car with lithium batterys, I should know I've done this, I used a 18volt 5ah hitachi cordless battery and it spun it over with ease, but what no one tells you, it killed part of the battery and after trying to revive these battery cells I had to renew them, I'm lucky because I know how to do them and trust me I won't be doing this again thanks colin
Thanks for this video, it works🥹👍
good video. thanks
It works, I just tried it. My car battery got drained overnight, I’m using a power inverter for my laptop.
My question is can you charge the battery the same way
Absolutely 💯 brother.. patients.. sabali
Figured this out with a sears battery in 1998. I have to do this now my cr-v has a dead battery. I needed to see if a 20v lithium was safe. Thank you.
