When your car battery is weak and can not start the car. Remember this video of mine. Or you can listen to music for weak car battery and try to apply it to see if it works. I have done this in practice and it helped me not to have to call traffic rescue. Thank you

@@5-MinuteCreative-IQ Yeah, I'll remember it and think to myself "sure ain't doin' that". And then I'll grab my jump pack or jumper cables. Or if I'm home I'll throw the battery on a charger. All much safer options. Problem is, if I'm home I can use a charger. If I'm away from home, I don't carry all that stuff in my car. But I DO carry a jump pack.

Thanks for your feedback. What do you think about this video? My video is just to give viewers a tip when facing an emergency (I have applied this method and found it very useful). Of course when we spend 70USD to buy a professional tool kit, it will be better. Thanks for your feedback.

Thank you for your comment. In theory it seems correct, but in reality the charging voltage of cars (including motorbikes) always fluctuates from 15-18V when the machine is running, so you can rest assured that the electrical parts of the car will be fine. Regarding the battery block, when connected to a 12V battery, the battery block will lose voltage, but think about it (when the drill is overloaded, the battery block will also lose voltage) and moreover, there is a protection circuit inside the battery block, and when starting the car, it will not take more than 1 minute, so you can rest assured. Good luck to you. Thank you, please give your comments on other videos on my channel. Thank you

​@@5-MinuteCreative-IQ you forget that the NOMINAL voltage of the Makita pack is 18V. A fully charged one will probably be 21V, so way above the maximum range of the charging lead acid battery (which I don't think ever goes above 15V, actually, so I'm not buying that it can fluctuate to 18V). Connecting the Makita battery will "probably" cause a drop in voltage provided that the SLA battery is well connected, but that's not a given (and not the case even in your video). If by any chance the battery is disconnected, you'll be pushing up to 21V into a system designed for the range 10-15. Maybe an older car has a chance of surviving this. Modern cars are almost certanily more susceptible (and more expensive to fix), nevermind electric ones, so this is already bad advice and it will age even worse. An ICE car, to start, needs extremely high currents (above 100A, pretty sure), so if the battery has protection I'm sure it will kick in and prevent the car from starting altogether (but it might still damage the car's electronics). If it does make the attempt to start the car, I'm inclined to believe the Makita battery either has no Short-Circuit protection or has a current limiting protection that, if the SLA is well connected, results in an effectively much lower voltage for a while (while the 12V battery charges itself back). The car will start as a result of the 12V battery being charged up again by the Makita battery operating at is maximum rated current. That circuitry may be something specific of Makita or even a certain production year of the Makita battery and you should not take for granted that it will work with other brands or models of power tools batteries, so the use-case is too specific and should not be handed out so easily. So no, you most definitely CANNOT rest assured of anything here. There's too many variables at play. One or more of these could happen: - you get lucky and start the car without damaging anything - the car doesn't start but no damage is done (still count yourself lucky) - the car doesn't start and the Makita battery is damaged (could be worse) - the car doesn't start and the car electronics is damaged (you're royally screwed) So, once again, this is bad advice! Don't do it!

@@filippopossenti1791 Yes. Your analysis is very deep. Very good. If you analyze more carefully, when the battery voltage drops to 0V, connecting the battery block is no different from a short circuit and it will not work. Therefore, my advice is only for cars with battery voltage drops and cannot start as well as old models like mine (I have tried this many times, it is very effective, of course I do it quickly and remove the battery block immediately). New cars probably cannot run out of battery so I did not think about it. Thank you for your in-depth analysis. Wish you good health and luck.

Thank you for leaving a comment. What you said is very true. Little knowledge is very dangerous and viewers with little knowledge are even more dangerous. When the car starts, the charging voltage in the car fluctuates at 15-18v. And in the battery block there is always an overload protection circuit for the battery. Think if you are in a remote place and the battery runs out, in an emergency, can a battery block like this start the car? You need an understanding of electricity. And try it with your own car, you will see the result, using a 12v battery will not work, use an 18V battery. Thank you for leaving a comment, please watch my other videos.

@ , your car battery becomes the load of your hand tool. There is now a voltage difference between those two and that cause the problem. Before you connect two sources of power in parallel, you need to consider so many factors. The reason why I commented on your video is that some people might connect those batteries in series which is bery dangerous. What if your car protection fails?

@@brandonfrancis8696 when you’re putting the load of a car starter on a drill battery, it will drop the voltage to a relatively safe level. He shows decently well to connect negative to negative and positive to positive. If you do that, this works fine but as I explained in my reply to the first comment, i would only do this if you have no other option and try not to do it often as it may damage the drill battery, but it does work. He is right except for the 15-18v charging voltage, as that should be 13-15v but otherwise he is right.

Thanks for watching and leaving a comment. You are very right, but in urgent situations you can do as in the video it will help you quickly in your work. Thank you very much.

I’d be more worried about getting the polarity and voltage right.

@@billpetersen298 the voltage is 18V, and there are internals in the battery such as a voltage cutoff, but yeah switching the poles would be bad, especially with all the electronics in a modern car.

Thank you for watching and commenting. I want to ask you, is it really that difficult to be a good person? When watching on TH-cam, you don't know what is useful and what is not. Watch the videos on my channel, especially this one, remember (when your car battery is weak, try this method) will it help you avoid having to call for help? Thank you very much for your comments.

@@ericleanne1628 here’s an idea… his battery cables probably are tight, and you must not have much experience with cars or drive a lot if you’ve never had a battery go dead, because it happens. Especially if your car has been sitting for a while. Even if they aren’t, this does work in general. As I’ve explained in my reply to the first comment, this does work, but I suggest only doing it if you have no other option and try not to do this often as it may damage the drill battery. Also, yeah, you don’t need to be a jerk about it.

That cable was so loose that when the alligator clip went in it, in some scenarios, would have been enough to make connection and start the car if there was juice in the car battery. Most issues I ever had were connections, most often from corrosion built up, or something loose connection, either than that, it was an expired battery - the odd time the accessory position was left on, and in that case a boost would work just fine.

@@Wookiemonsterfreak Thank you for watching the video and leaving your comments. When you have the opportunity, you can try this method, it will give you unexpected results. Remember to take an 18V battery. A 12V battery will not be able to start the car. An 18V battery when connected to a car battery will cause a voltage drop to an acceptable level. Remember to start the car immediately after connecting the battery to avoid overloading the battery. This method is used in emergency situations, it will help you when needed. Thank you very much.

@TommyBoyce11 Yes. You are very smart. You understand the electrical system very well. And this is just a small tip when necessary. In fact, our cars do not run out of battery often, only when we leave it for too long or in some special cases that cannot be started, this is a quick way to help us avoid having to call for help. The car's generator system when operating, the charging voltage for the battery fluctuates from 15-18v, so the car's electrical system will be fine. And in the battery block there is an overload protection circuit, so if we use it quickly, it will not harm the battery. Thank you for understanding people like you. Please give your comments on my other videos. Thank you.

I have done this often when other cars run out of power, the 18v battery when plugged into the battery will have a voltage drop (not harmful to the car's electrical system) and the drill battery has a high discharge current (the drill can work when under load, sometimes the motor does not rotate, the battery can still withstand it for a short time) and the battery has a self-disconnecting circuit. Therefore, clamping it together into the battery system for only 1 minute to start the car is not harmful.

⁠@@5-MinuteCreative-IQ you’re right about the voltage drop part (to a point), but either way it’s still not very good for the drill battery. In a pinch, and if you have no other option, it will technically work, but I still wouldn’t do this regularly.

@TommyBoyce11 Thank you. Everything is fine if we apply the right devices to their main purpose. In some necessary cases like this we can apply it. In each battery block there is a battery protection circuit so we can apply it when necessary, and I believe our car cannot damage the battery often. The video I show you can start the car when necessary without specialized equipment. Hope my videos will be useful to you. Wish you good luck. Thank you very much. I look forward to many comments from you. God bless you

@@5-MinuteCreative-IQ I get that the battery has circuit protection, but drawing so much current that it gets activated and making the voltage drop that much isn’t great for the battery. Car starters usually draw anywhere from 200-500 amps, yours probably draws 200-250 since you have a four- cylinder engine. Yes, drill batteries usually have high discharge cells, but usually not to the extent of starting a car unless maybe it’s a large battery meant for very high power and/or big power tools. Your Makita or similar drill battery maxes out at about 30 amps on average, according to multiple sources. Normally I would link them, but they don’t work in comments anyway. The circuit protection is mostly just for keeping the cells from overheating or extensive damage, so its current limit will be relatively high. Again, if you’re in a pinch and have no other option, it will work, but I wouldn’t suggest doing it often unless you don’t need that battery much or don’t plan on the battery lasting for a long time. I wasn’t necessarily trying to prove you wrong so much as I was trying to say that this is really only a one time or emergency thing, but it will work. God bless you too, and have a great day.

If you run the cxt makita or the m12 Milwaukee it would be fine though but yeah m18 and lxt is actually more like 20 volts when fully charged.. There is a way to reduce the voltage down to 12 - 14 volts

Nice 👍
