I know you made this two years ago, but I kept searching videos to jump my battery and yours was the only video I seen how to hook the cables. Grabbed me two pennies and my hyper tough drill battery ran outside and did exactly what you did only I waited about 2 minutes before trying to start and I be damned if it didn't start. Thank you so much. Forever grateful for your expertise sir
Left the lights on my van today. All day. No lights on dashboard it was that flat. Used 18V drill batteries to charge the van battery. Only had some thin gauge wire on hand though so had to pulse charge it to prevent burning the wire up. About 20 minutes and I was up and running. Took 2 drill batteries to charge the van bettery though. And it flattened them completely. But it got me home!
It works because the 18v battery has a higher voltage potential than the dead 12v car battery. The little battery begins to charge the big one as soon as they’re connected to each other, bringing them slowly closer to equilibrium with each other. Once the big battery has had even 10-20 seconds to absorb this surface charge, the starter can then draw enough combined amperage back out of both batteries at once to turn the motor over for a few seconds (only need a few seconds to start!) If the big battery were missing or disconnected, it would not work as the 18v battery can’t provide enough instant amperage all on its own. So basically the car’s battery is used like a large capacitor for a moment until the engine starts and it can get a “real” charge from the alternator.
Awsome survival hack. I'll try to remember that if ever need a jump or someone else needs a jump. I allways have my cordless tools wilth me going and comen home from work 👍
I'll try and use my Loftek portable battery jump starter if I or someone else needs a jump, but it's nice to know my 18v battery can jump start a car as well!
@@jesusmariarodriguezolivarr2477 Thanks for that info Jesus. I have a video coming up shortly on one of those jump start devices. I'm reviewing it now.
Yep, that's why I had a dead battery to begin with. My old alternator went out while coming home the previous night and the headlights ran the battery down. I got a lift into town to get a new alternator and once I installed it, the battery wouldn't turn the pickup over.
By the way.... Had a dead battery on my truck the other day. Had a 28 volt 2ah porter cable battery in the truck with some jumper cables (and two pinneys). Worked like a friggin charm brother!!! Just wait a minute or two and TURN DAT KEY!
@@BlueCollarDIY I got stranded off grid during a black out yesterday evening. Boost from a Tow truck isn’t even an option here. Thank God for my fully charged power tools in my truck. I rigged my Milwaukee drill battery with some 14/2 and a booster cable. Didn’t even have to wait, she kicked over on first try. Amazing 🤩 🙏
Probably start LOW energy PETROL [GAS] Engines BUT i just tried an Bosch 18V fully charged on a UK VW Polo 1.6 TDI and NOPE just will not Turn over [Yes i checked everything] Ended up using a JUMPERBOX for UPWARD of 2.0 Diesel engines [BOOSTED right up].

Thank you Allen for explaining how a 18v drill battery can jump start a car. I appreciate the explanation.

Love it- the penny trick is awesome-just 18 volts?
Wow! didn't think there would be enough amps
Me neither. I thought it was just a hoax, but I'm glad to know I can use a cordless drill battery to jump my pickup if I ever need to in an emergency!
@@BlueCollarDIY I did it with my friends car the other day.
@@johnrhodes3350 That's awesome! I bet he/she was surprised you could jump start their car with a 18v cordless drill battery!
Good vídeo. Only 80 to 120 Ampers are nessesary to jumpstart a car with low battery in warm weather
@@jesusmariarodriguezolivarr2477 Thanks for that info Jesus. I have a video coming up shortly on one of those jump start devices. I'm reviewing it now.
That is the sound of a GM. I’d know it anywhere
Yesssiree!
Amazing mate I even see you even got a new alternator on there
Yep, that's why I had a dead battery to begin with. My old alternator went out while coming home the previous night and the headlights ran the battery down. I got a lift into town to get a new alternator and once I installed it, the battery wouldn't turn the pickup over.
I made little jumper cables for a drill battery use it as a jump box
Yup this just got me out of a tough spot. Thanks
Any concept that could really help I do adore.
Thanks Charlie. I feel better knowing that having my cordless tool batteries with me now gives me another option should I have a dead battery!
Blue Collar DIY Keep it near you in cold weather (like in a chest pocket) so it stays warm.
Ima just go head and use a pinney on this here battry.

Wanted to try this. My only issue is I can't identify positive and negative terminals on my 18v drill battery.
Is it a Bosch? If so, there should be a tiny + and - next to the terminals.
You can use a simple multimetre to know which site is pozitive or negative
..by the way thank you for this survival hack 👍
Watch how it goes into it's charger
Did not work for me. Very frustrating!
Awe man, I'm sorry to hear that. Was your cordless battery fully charged?
@@BlueCollarDIY I am not sure. Has been sitting in the garage, but had some charge.
@@nashsimcov4091 Yeah, I had to make sure my cordless drill battery was fully charged before it would jump my pickup.
Didn't believe it at first but having no other choice i had to try, OMG IT WORKED!!! 😁🙏
That's the way I was. Didn't have anything to jump my pickup off of, so I decided, what the heck, might as well try it!

Truck sounds rough...
382k miles with an exhaust leak. But she keeps on keeping on! I just hope I never have to jump start a car with an 18v drill battery again!
👏 it worked you saved my ass thanks for sharing 👍
You're welcome Cooper Bee. I still find it amazing that you can jump start a car with a cordless drill battery!
-15 today here too my battery was an ice cube too
@@cooperbee408 WoW!
Just worked with a M18 12amp!
That's great to hear Scott! Crazy stuff isn't it? Starting a car with a cordless drill battery, who would have thought that?
buen video. gracias.
You're welcome!
Are u sure nobody is in the front of the car? With some cables or a jump starter maybe?😁
Cause u need amps to start, not voltage
That is Awesome.
Desperate times call for desperate actions...lol I was just as surprised as anyone! :)
