Car Battery Danger - But It’s Not What You Think!

[@meowstre]

The car battery was my biggest fear working on a car. But this put my fears at ease. Thanks so much man.

[@ngalam4756]

My man really touched both terminals with a wrench to prove a point. Thanks for dispelling all my fears when it comes to battery replacement!!!

[@BudgetMechanicHawaii]

Haha happy to help 🤙🏽

[@saysomethincute]

Great video, really put my irrational car battery fears at ease.

[@a.i.dimmer4616]

same here,my car's tail light wont turn off so i have to disconnect the battery or its gonna drain it overnight till i can take it to proper mechanic next day..this helps me with ease.

[@Adrian2140]

Same here. Saw some videos of batteries exploding and I always treat them like butane gas containers. I know they are probably safe and built to last but I can't shake that fear.

[@dantindell336]

me too

[@reverendbluejeans1748]

I thought it would not hurt me because I got rubber sole shoes on.

[@rubydreams6345]

Thanks! I got sparks from my battery years ago and have been terrified of them since. I jumped when you touched both terminals at the same time. I feel a lot more confident now!

[@dekas5357]

Same

[@alexanderlittle358]

Finally a good explanation as to why the negative is removed first, thankyou!

[@foxtrot.tango.whisky]

Man, thank you! This is damn well the most clear, concise and informative video regarding the straight forward instructions on the disconnect / reconnect procedure surrounding vehicle 12v batteries. So many others have tried to do the same and they confuse the topic, they leave out vital information such as the way you demonstrated a 12v battery's potential (or lack thereof) to pass current through a human body. Great video dude. Haven't seen any other vids of yours but I've subscribed, liked & I'll be sure to check out some more of your channel's catalogue of videos.

[@minakoto00]

Seen couple of videos but either they disconnected the positive first or they didn't explain why. This is the best video on youtube yet to explain this, thanks a lot!

[@BudgetMechanicHawaii]

It’s a common misconception for sure!

[@PrideSage99]

I wish I could like this video twice, thank you for being so concise about people's main concerns. I am a techie and even I was afraid of these things. You made me feel a lot more confident about fixing this battery terminal for my UPS!

[@BudgetMechanicHawaii]

Thanks man 🤙🏽

[@jeremiahalvarez1500]

Bro I jumped when you touched the battery with the wrench , caught me off guard

[@LORDRA1DEN]

Thanks! I've always wondered, but never been brash enough to go poking around the car battery. At least now I know what won't hurt. And a good way to remember the order is when you're disconnecting, you're "taking away", or subtracting, which is a negative sign, and when you're connecting, you're adding, so positive first.

[@viktorpavlovych]

Wow this is super useful way of remembering this, thank you!

[@LORDRA1DEN]

@@viktorpavlovych Yeah, I was actually sitting there thinking, "How am I going to remember the order," then it dawned on me. lol

[@issachra2925]

I thought the sparks had to be click bait as far as I'm concerned this man is magic

[@almarma]

Amazing video. I bought a used car last week and the seller did a last minute battery change to deliver it to me and I saw that a cable is pinched underneath it so I tried to unscrew the positive terminal first and the wrench touched a metal part and a big spark came. I freaked out so much I bolted it back and decided to never ever touch a battery again. But after watching your video I think I'll try again tomorrow. THANK YOU!!

[@Xshadowangel6661]

I don’t know anything about cars but I’ve always wanted to learn. Thanks for making my first battery change a breeze! Will be sure to watch more videos :)

[@AndyYoung-od9ou]

He missed step 0, remove all rings and jewelry. I still have the scars when my wedding band melted.

[@gregorybown]

This is an excellent description of all the potential risks. Thank you. I would only add that reversing jumper cables or connecting a battery charger up with the cords reversed can potentially blow out part of your cars alternator, specifically the internal switching part, but effectively turning a simple battery replacement into a very expensive repair as alternators are quite expensive in most cars and labour can be equally expensive depending on the location of the component

[@CrashCarson14]

Thanks for explaining the fundamentals on why some ways it’s not dangerous. The hand thing did help

[@s.f.9208]

Thank you!! I was literally picturing the thing zapping me until I saw this

[@atabhatti]

Great video! Thanks for all the details and for removing fear.

[@kansas4451]

Best video explaining the battery. Thank you.

[@Teshelle18]

This is the most clear, concise and explanatory video on this subject on KZbin. You’re a baddass...now can you come Car Whisper my Jeep?! 🙏🏼

[@random-iy2xm]

It is widely understood within mechanic and technical trades that wearing jewelry, especially rings, poses significant risks when working with mechanical systems and electricity. These dangers are extensively highlighted in training programs within these fields. Jewelry presents multiple hazards. Firstly, it can become entangled in machinery, leading to severe injuries such as amputation. Secondly, jewelry, including rings, can conduct electricity and increase the risk of electrocution when in contact with live circuits. Gold rings, in particular, make excellent electrical conductors, potentially exacerbating the severity of electrocution compared to bare skin. Thirdly, in a scenario depicted in this video, a gold ring could become fused between a battery terminal and the wrench, resulting in severe burns and potentially the loss of a finger. Additionally, sparks generated around batteries pose a risk of igniting hydrogen gas explosions.

[@bradh1870]

Back when I was a kid my uncle used to replace batteries (car, mower, 4-wheeler you name it) like he was handling nuclear waste, so I grew up terrified of the things. Thanks for this one.

[@jacob2483]

After creating a burn on a ratchet and wrench, I finally watched this lol. I usually do not do stupid things, but this is one of them that I should have looked into sooner.

[@Mr_Gran]

I've watched this like 6 times as I always forget the colours -/+ and order for connection. Thanks, it's been super helpful

[@yubi4291]

Amazing video. Thank you very much for uploading this. Much appreciated.

[@thcall6441]

Thanks. I always have to figure out by using the reasoning-Neg first. But you triggered a an easy way to remember: “The car’s frame acts like the negative terminal “ until you disconnect the neg terminal.

[@drewpyper]

Thank you so much - this is exactly the video I needed to see. Thank you!

[@likeasir007]

Awesome video! Thank you! I got a bit scared when the terminal sparks when I jumped a dead battery in my scooter. Now I know why and how to handle it. Thank you again!

[@ciprianpavia]

How much is affecting the battery internaly connecting the plus terminal with the negative terminal together for few seconds?

[@christinedeegan7602]

Thank you so much for this video. I really appreciate the Proper way to disconnect and reconnect a battery.

[@DroidMastertaylor-gang-or-die]

Thank you very much for this video. I learned alot about car batteries. I really tought they were way more dangerous then they actually are. I can now go confidently finish replacing my battery.

[@BudgetMechanicHawaii]

Glad it helped!!

[@luddel4747]

Thanx! What are the odds that you damage or shorten the battery’s lifespan if you do a quick short-circuit like the one you showed?

[@thecarman3693]

It's a bad thing to do regardless. All the power is then delivered to the battery's internal resistance, and since a dead short (wrench) will have essentially no resistance of its own the battery can quickly overheat and suffer permanent internal damage to one or more cells.

[@Goooooh]

SHEEEESHH 😮‍💨 I been scared of my car battery for 28 years thanks bro

[@Adventure_Always]

On a diesel truck with 2 batteries in parallel- should you disconnect both batteries to work on electrical? If so, could you explain what order this should be done safely. Thanks!

[@MakuLabs]

Thank you for making this video. Makes me much more comfortable approaching my dead battery replacement DIY. Fingers crossed (not the jumper) lol :)

[@p373r21]

Can u touch metal with your hands when removing the positive terminal when the negative terminal is off.

[@dekas5357]

The removal tool is metal, right?

[@Gelenvader3]

Thank you so much this removed my fair of car batteries

[@Liftingmycross]

If you remove the negative first should you still remove the ground ? Or are you safe with just negative

[@gillr9193]

Thanks for this. I've never taken out a car battery before and I was really uptight about it until I saw this clear explanation

[@rideresponsibly1163]

"Start with black, end with black" as others would say.

[@BudgetMechanicHawaii]

Charged statement there ;)

[@OthmanAlikhan]

A super thank you for making this video. I have always been concerned about safety when it comes to car batteries. It is great to see things put into perspective =)

[@A.AInc.]

I just accidently let a wire make contact from the positive to the negative terminal on one of my brand new leisure batteries.. Am hoping that a quick touch like that with the spanner hasn't affected my battery in any way ?

[@richiej5812]

Straight to the point useful information....good video thanks.

[@mrlwilliams9234]

Thank you this was helpful, I'm currently doing a vehicle maintenance course, but sadly I've just got this fear with electrics and it pisses me off. But this video has at least eased my fear. Thanks. 👍

[@utube5361]

Hi, if we connect the "Keep Alive Memory" on the OBD2 port (to avoid computer malfunction) when working on the alternator or something else with the car battery's negative terminal disconnected, is it safe from creating short or spark ?? Will the external power that feeds the computer through the OBD2 port run through the whole electrical system or just the ECU itself ?? Please advise

[@duaneplacek1716]

Great video brother I can never remember the proper order LOL but your video explains it very clear best battery video I've ever seen thank you so much

[@doormaat5033]

after the negative terminal is disconnected, is it still unsafe to accidentally make the wrench touch both the positive and the body of the car at the same time? im careful either way just in case, but id like to know for sure

[@Diverboy35]

I have a question..... once you disconnect the negative terminal (having light issues and have to cut power) can you just let the negative hang on the side of the battery? What if it touched metal?

[@duncanm5927]

Im 15 and started working at an autobody shop, held the battery by the wires, one came loose and smacked into some metal and sparked. I thought I almost got electricuted but I guess it wasnt that big of a deal

[@VFamilyJMJ]

I disconnected the black negative first and still got sparks. The negative is connected to the car like this video. Do you know what the problem is? I have a 98 4 Runner

[@BudgetMechanicHawaii]

If the negative terminal of the battery is completely bare (not connected to anything) there’s no way you’re shorting out the battery. So I’m not sure how you’re getting sparks!

[@VFamilyJMJ]

Budget Mechanic Hawaii I tried connecting the negative part of of the battery again. It worked. It did spark again for a second but went away. First time it smoked a little bit.

[@baileydustin2139]

This could be the most effective video on youtube.

[@Carrottopsarentred]

Why do you connect the positive back up first when replacing tho? Couldn't you bump the frame of the car and make sparks?

[@Goooooh]

With putting the battery back why do you have to put the positive first? what would happen if I connect the negative first

[@jstucks9928]

Love this. Just needed to see it! Is this the same for all types of 12v battery including lithium?

[@thecarman3693]

Yes ... but keep in mind that different battery types have different internal resistances. Both AGM and Lithium batteries have very low internal resistance compared to lead acid types. That display you saw where he jumped the terminals with a wrench done on an AGM or Lithium battery could have resulted in instantaneous welding of the metal to the terminals, so they must be handled with extreme care. Those batteries can deliver up to 5000 amps upon contact. The benefit of having such a low internal resistance means that almost all the power supplied by the battery is delivered to the load you are putting on the battery, such as the starter. The starter will then get all 12V applied to it, whereas the internal resistance of a lead acid battery's internal resistance can absorb as much as 2V of that 12V, meaning the starter only gets 10V.

[@thecoolnessification]

I got a big bass system installed in my car and I"m going to be trasnferring all that to another car soon. Question is since I've never done the whole 2nd battery for a bass system before once I remove the bass battery and amp thats in the trunk what do I do with the pos and neg battery wires that are in my trunk that hook up to the amp? It cant be good to have a live red wire with an open end on it and I want to leave the wires there in case I decide to buy another system for that older car so I'm assuming I can cap them somehow but I dont know with what or could I just cover them with electrical tape. If there is no amp pulling juice from them are the wires just dead wires and not dangerous ?

[@BudgetMechanicHawaii]

I’m assuming they are leads directly from your battery under the hood and no you shouldn’t leave them exposed. I would disconnect them at the battery or at least cap them very securely (not tape!)

[@YOQishere]

Seriously. thank you so much for this video. This put me more at ease, I thought I would electrocute my self and hated removing the connectors on my battery.

[@crazytech5755]

I just squeeze the terminal with my pliers using my body weight. Never had one come out. I know for sure it's not the best thing to do, but works ;) Just shrink wrap it really tight, and tape.

How easily can a battery explode? I am currently using an extra car battery inside an rv to power some music equipment. I also have a solar panel hooked to the same battery to keep it charged, so there is a drain on it and a charge into it (small 20 watt) at the same time Thanks!

[@BudgetMechanicHawaii]

I’m no battery scientist but lead acid batteries in car applications do not easily explode. The most dangerous is when sparks or flames ignite the battery offgas that are emitted when charging. So keep fire away from your battery and you’ll be fine

[@Hibachipower]

When car is running is it also safe like when car are off?

[@almarma]

driving without battery? No, it's not safe. I've read somewhere that because the car creates electricity while it's moving, that electricity has to go somewhere (to the battery to recharge it) but because there's no place, the voltage can increase and can fry your electronics. I'm not an expert at all, I just read somebody explaining it a few days ago and I remember it

Great Video . Such a useful video.

[@Jcrosay]

Question! While jumping my car battery today, there were a few large sparks when grounding the last negative to a piece of metal which was probably 20 cm away from the battery (I couldn’t seem to find anything further) and I read that the negative should be grounded at least 30 cm away from the battery. My cables also had a circumferential crack exposing the wire, which I had covered with electrical tape. I’m wondering if either grounding too closely or the exposed wire may be the culprit? I’m also curious to know if sparks are as dangerous as they’re made out to be. With hydrogen gas in the mix, surely a spark could result in a battery exploding? I have a lot of battery anxiety; in fact, I was so hesitant placing the cables today that my partner was furious with me .. 🤣 I’m hoping to learn more and hopefully put my worries at ease, as living in such a cold climate results in frequent battery jumping.

[@lhow3100]

The reason you want to ground your last cable away from the battery is because it will produce sparks and could result in an exploding battery. A battery that has been charging for a while off-gases hydrogen gas (as you mentioned) and can be explosive. The chances of the battery actually exploding are slim, but it is a possibility. Connecting to a bracket on the engine still produce sparks since you are completing the circuit, but it is usually your best bet to avoid anything from happening. 30 cm is plenty of space.

[@BudgetMechanicHawaii]

Correct. Sparks are normal. Better to have the sparks away from battery if you can

[@williams5464]
