*UPDATE:* After the battery running for a few more days with no problem, it left us abandoned at a gas station! Fortunately someone gave me a boost.
So to diagnose the problem, while the car was running I measured the voltage and it was 13.5V, but as soon as I turned the car off, it dropped to 9V. So the alternator was providing juice to charge the battery, but the battery didn't hold it.
I also put an ammeter and measured car's off current. When I locked the car, the current was at 110mA and after one minute dropped to 3.5mA. So there is no leakage current either.
I brought the battery home and charged it with my supply. The voltage would rise to 14.5V with a steady 2A, and then would drop to 11V when I disconnect it.
In conclusion, I am sad to announce that the battery has passed away. It is not a serviceable battery either, so I shall take it to the dumpster where it belongs! (I mean I will recycle it)
ElectroBOOM can you make a video on how to mod a big brick of a plug to a regular plug and relocate the brick lower on the wire? The brick covers all the other plugs on the outlets
OMG dude, FULL WAVE RECTIFIER, 120 Volts from the wall!! Bring that baby back from the dead! I do it all the time. ( Just remember to put a 40 watt bulb on the AC side ! Yeah, or leave it out for laughs to start... )
Sounds like one of the cells in the battery shorted internally, or the water level in a few cells is super low and needs a top off of distilled water. If your car were a manual transmission, you could give it a rolling start using the momentum of the car with a quick pulse of the clutch to couple and uncouple the momentum of the transmission with the body. With 9V, that's more than enough to start combustion and run the alternator too. Too bad you can't give automatics a rolling start without completely destroying them lol.
It's too bad starter motors require such ridiculous currents to run. If starter motors gradually built up kinetic energy in a flywheel and then dumped it all at once into the transmission, it would be more reliable to start at lower voltages considering the low instantaneous power available in dead car batteries.

@@Djungelskog69 what made you think it was ok to reply that?
David Labella, fuck off
What happend
I myself, do have a battery that was discharged to absolute 0v and was able to recharge it.
It still works and hold a quasi perfect charge over a long period of time.
So it's not impossible.
But it's pretty rare. I only saw this on one battery.
The others i tried to save had, at least, one cell totally shot.
nn tu peut pas etre la 😨😨😨
How
I, in my infinite dumbassery, charged a battery fully backwards, then was able to fully reverse it again somehow. It was really dead when I reverse charged it, but somehow it made the journey from 10V or whatever it was at, to -13V and back to 13V and still seems to be working.
ita? quasi means almost in italian
@@lamuzzo5120 quasi seans to have the same meaning its a quasi almost i think
“Never had a problem with leaving the lights on.”
Me: This explains a lot.....
Deal with this often as a pro technician. Anything over 20mA is abnormal. You're going to want to find your draw, and use a more accurate meter than a janky amp-clamp.
That's true, but then again I can't trust a clamp ammeter with accurate low current measurements. Should do a proper measurement... next time the battery fails!
I would also wonder when he took that reading too. If it was right after he shut off the car, the computer is still doing some work for a time afterwards. For instance, a timer for automatically locking the car and turning on the alarm. Heck, my car still lets me open and close windows for a short amount of time after shutting the car off, and stops letting me either after I open the door or after a certain time has elapsed.
Not necessarily - it depends on what your car is doing while _idle_. Mine draws ~120mA to cover things like keyless entry and mobile connectivity (incl. remote heating activation and such fanciness). Given that the battery holds 80Ah that's not really an issue. Plus, it's smart enough to kill the mobile connectivity and pretty much anything extra apart from the basic on-board computer control (you even have to use a physical key to unlock at that stage) once it estimates less than 20% charge - then the draw drops to mere 14mA, according to the service manual.
Especially with normal car batteries, those suck for sustained low current. With some, a 1A load won't run significantly longer than a 10A load.
Depends on the vehicle and OEM. My vehicle has a rated parasitic draw of about 40 mA.
"I thought it turned the lights off after a while." Apparently when the battery runs out of power. :P
Haha yep. I kept leaving the interior light on so I installed one of these tinyurl.com/y7ehpoes

How do apartment people charge their car battery without disconnecting and bringing it inside?
Sh@# you are right! Didn't think of bringing it upstairs and charge it with my power supply!
Confess it, you did but it wouldn't be fun that way
ElectroBOOM Can you make a video to explain why the capacitor blew up when connected the wrong way or beyond the rated voltage?
For sh!#s and gigs you could bring a battery down with an inverter and a battery charger which just seems pointless lol
I've had to do exactly that. Only downside is that the car forgets the time, and you have no security alarm either.

Clips are still good, just needs some new wires.
You know you did a good job sacrificing alligator clips when the wire is good and the clips melt.
I was loling so hard at the smoke when he started it. So funny
The alternator putting 90-100 amps through them will do that.
shubham preet nope look at pinned comment he wasted wires and clips
8:19
Actually, yes you will need to replace that battery. You've already sulfated the plates and knocked a crapload of lead off the plates by jump starting the battery so many times and using the 90A alternator to recharge that battery. As a diesel technician, I can personally assure you, that your battery needs to be replaced if it won't hold a charge after not being charged for several days. We have to change all four 950cca group 31 batteries within the first 2 years of truck operation due to all of the constant on/off cycles of the engine and use of power inverters. A far cry from the 5 years you'd typically get from a standard lead acid battery in a consumer passenger vehicle.
Batojiri1 I was going to post something just like this! The sponge lead is toast, and the cells aren't going to hold a charge... His alternator is next
I'm aspiring to be a Diesel Technician, but I need money for tools
Get firefly carbon foam batteries
It looks like the OEM battery. They usually have only the minimum cold cranking amps, and don’t last very long.

I would recommend setting the dome light to the middle switch for door. Toyotas don't have any protection from lamps pulling the voltage to zero.
8:18 ffs i was watching this at 4 am with the lights off
**long term ptsd**
I had this exact same scenario: battery was on its way out, having done like 9 years of service, died one morning, I managed to start it by pushing it pretty fast then quickly hopping in and letting the clutch up with 2nd gear engaged, drove to my destination and after like an hour the car still managed to start on its own, but the next day it was obviously dead again, so a new battery is a must in your case too :))
9 years is a good long life for a lead acid battery. Congratulations. I suspect that adding super capacitors to an existing battery will improve the life of the battery as long as the battery isn't abused, like being drained dead. Using the cap+battery can certainly improve the cold cranking amps delivered to the starter.

(Edit: looks like you know some of this 😊) Tips:
1) Avoid sulfating your battery by starting the car once every three months, or connecting a maintainer charger to it. Saves motorcyclists from buying a new battery every year.
2) check with an ammeter if any current is being drawn while the car is off. There are videos on what milliamperage is acceptable. Southwire has a clamp DC ammeter to give an approximation if you’re concerned a large amperage is being drawn.
3) test your battery with a carbon pile load tester, burn don’t leave it connected too long, and don’t buy the Chinese shunt (literally) with the “cooling fan”. The battery may need replacement,
4) You can buy a jump box to do some of that job for you on smaller vehicles 😊.

*I would request a video but i honestly haven't a clue whats left for you to do.*
Replace the battery, he's damaged the plates by jump starting the battery and charging it with 90A constant current from the Alternator.

Easy: Do the video again in a closed building with smoke detectors! :D
You will be replaceing that battery in 0-3 months. Its likely already leaking all over.
So far it has been running like nothing happened! Hopefully it will stay this way
I think you should buy spare battery and carry it in your trunk just in case

What a good time to review charger/desulfators like the Battery Mindr brand. They seem to work...sometimes. It revived one old battery of three I tested to 'like new' performance (charges to 13.6VDC, can deliver 460 cranking amps several times, holds the charge at low temperature, etc).

8:48 *when someone says DC is better than AC.* lets be honest. AC is better
They each have their perks
Brad Schlangen true
For me the best part of DC is the simplicity of calculations, and electronics would be a lot harder (if possible) to make with AC, but you need AC to run a transformer with helps you afford the electricity in your socket, and lets you run devices that require different voltages on one common voltage.
Three phase AC electric motors are far more powerful than their DC counterparts can ever dream

Did you check the levels, top the cells off with distilled water and charge the car battery again. But it’s time to replace it soon.
And buy some LED lights for your interior lights. Maybe next time it will survive a couple days with the light on.
This car has a maintenance free battery. There is no way to add water, they are un-openable. Cars haven't come with maintenance batteries for a long time.
@@owencarlucci6959 Can't you just buy a battery like this, though?
@@MrCh0o maintanence free or maintanence?
I know you intentionally get yourself shocked for comedic effect, but do NOT spark alligator clips near a car battery that has been charging. My father used to spark them to test if the battery had charged, until the escaped hydrogen from the battery charging blew up in his face and he had battery acid flushed from his eyes at the hospital. I know you don't mind being electricuted, but do you want battery acid in your eyes?
Maarek Aabmets If the battery leaks hydrogen then it might have a problem. There shouldn.t be hydrogen in a car engine, it's way too dangerous.
Well, this particular incident happened aver 15 years ago and most probably used the older batteries that you could yourself add distilled water to. While new batteries are sealed and shouldn't release hydrogen, I would still not spark near a battery, especially if it reads 0V, as that might mean that it "might have a problem"
Maarek Aabmets I wouldn't do that now, but i did never imagine that a defective battery could release hydrogen.
Upon further reading I found that the wikipedia page for Lead-acid battery has a section called "risk of explosion" where it states that "Excessive charging causes electrolysis, emitting hydrogen and oxygen". Excessive charging might not be possible with the newer chargers, but my father has always used an old transformer charger that keeps the voltage at 14V. However, if I remember correctly, the new modern charger I bought a couple of years ago still recommended charging in a well ventilated area.
You'd have to be charging the battery for a while to worry about that. He was charging it **just** enough to jump it so I doubt there'd be much hydrogen there. The 15 minutes he ran the car to charge it would be a little more dangerous time to be making sparks but probably fine given the radiator fan is running, dissipating the hydrogen. A real car charger being run for 20-30 minutes would be cause for concern in creating sparks around a battery especially if no fan is running to prevent the hydrogen from collecting. Most lead-acid car batteries are still not sealed, the sealed ones cost a lot more. Like if it's an AGM battery you wouldn't worry about it since that's sealed but it'll run you around 130 bucks at the cheapest when I can get a standard car battery at the cheapest for about 50 bucks with a core trade around 65 without a core to trade. AGM are generally worth the money since they last longer though and they're a little more physically robust than lead-acid and you don't have to worry about electrolyte levels (Very few people check the levels so they die faster than they ought to).

Great job happy to go see you not get hurt this time
Jep, did a similar thing once (or 20x) when my car battery began degrading rapidly, had a few smoking cables, even after I upgraded the thickness of the alligator wires.
That “small” lead acid battery puts out some serious current, and if your battery was recoverable, it is no longer. You have to go EXTREMELY slowly with dead lead acid batteries and then you might get a couple months out of the battery. 250ma max until 9v then 1a to 14v. That way the plates get coated more evenly.
soupisgdfood this is electroboom, of course he killed the battery
You first assume he wanted to save the battery instead of torture it.
soupisgdfood I've bought my first car in winter, haven't touched it until 3 month later I've got a license. Yeah, battery was dead as hell. But after 2 days of slow charge (something like 100 mA) it started to charge normally and I've had 5 or 6 years more from that battery!
NiMH, lithium, lead acid...should always start with a very low current before it reaches a good voltage. Gradually raise amperage with voltage. A few amps max. The more forced the charging the higher the chance of shorting an individual cell.
Why did I just get notified of this video 3 days later ?! 😤
it was first released to patreons before making it public
Me too
Can't get enough of this tech craziness!
With these vlogs, i always am anxious for if something is gonna explode and its not on purpose
Me when I see the video title: "Oh god what now?"
I'm curious if this battery will still be powerful enough in the next winter (if it survives that long).
I had some batteries that were discharged until nothing worked. After recharing them, they worked as long as it was warm. As soon as the winter came and temperatures dropped
GrafKrolock82 I think you might also find that when it's cold, the engine oil is thicker and doesn't lubricate the engine as efficiently, especially at startup
sometimes the storage thingy infront of passager desk has a light that runs whiles someones open it, somtimes if its not properly closed the light wont turn off and it will lead to fast and sneaky discharge.
Glove box, that storage thingy is the glove box, but your totally right those can be very sneaky because sometimes those lights dont shut off when you close the glovebox cause the switch isnt fully depressed, had that happen with an old work truck i had, took me a embarrassingly long amount of time to find it.
I used to have one of those compact pocket-sized lithium batteries that were made as jump starters, super impressive little things, I highly recommend, I bought it as it had a USB port and could charge my phone several times from flat before needing recharge. Jump started 2.2L Boxer vans a few times before needing a restart.
1:53 There is a light on behind him. was this intentional?
No, but he said he thought they shut off automatically (which they don’t).
@@theaviator1152 watching again, he fiddled with the lights before charging the battery, I think thats when the switch was turned to the on position since he never had a problem with that before.
or maybe his daughter or wife left it on, since those lights turn on and off automatically he probably thought it was normal, walked away, and didnt know untill after the battery died.
Just replace the battery with the supercapacitor and jumpstart it.

I get the feeling that Mehdi is the kind of person to reuse paper towels at least a hundred times.
Could you replace your car battery with a smaller battery and a super cap Bank? Isolate the super caps with a solenoid that only connects when the ignition is on (because the super caps will drain the battery if connected all the time right?) So when you want to start, turn the key on and wait a few seconds for the Caps to charge and then crank.
Dave dablave czcams.com/video/z3x_kYq3mHM/video.html
Yes, the simple answer to why not is that supercaps are more expensive.
Sure, but that would be impractical and expensive
rfmerrill not really. Those super caps are around $12. 30 bucks for a small SLA battery and $10 for a solenoid. $112 is about what you'd spend for a car battery anyway. considering the whole set-up would probably be 30 pounds lighter than a full size car battery it might be worth it for a race car or something.
You could even make a lithium ion jump pack that would actually work without blowing up.
BurntTransistor maybe more complicated but not impractical. I have an ignition controled solenoid in the charging circuit for my dual battery setup. It has been working fine for over 10 years. I have killed my starting battery several times since then and I've had to engage the solenoid and let the starting battery charge off the secondary.
The breaking point might be how quickly the SLA battery can charge the caps. They might take a charge so fast they would wreck the battery.
The clamp meter works only on AC current.
jose Luis there’s clamp meter that can measure dc current.
@@ItsJustMeMusic Really? I was not aware. Tks.
I had this happen to me too. When it was discharged, there was huge internal resistance in the battery. I just slowly charged it (for like 15 hours) and it was all right.

More like: Vive la resistance !! Get it? like for ensuring too much current isn't drawn? no? never mind.
You should do a proper current measurement with a regular ammeter. I think there's something else draining the battery
Its his battery draining his battery....... He's attempting to recharge a sulfated plate damaged battery with 90A constant current.......
It looks surreal seeing you being actually careful when connecting the wires.
This is a fun video. For anyone curious about a dead car battery though:
If the voltage is below 5 volts at rest, it's probably a lost cause
If the resting voltage is around 12 volts but drops below 9 volts while trying to start, it's probably done for.
If you can get the car started and the voltage is less than 13.5v, the alternator is the problem.
There you go. You are now the neighborhood go to person when someone's car won't start.
Tomorrow the car not start again ;-) Buy a new battery before you kill the car engine management computer
You will have a VERY hard time destroying an ECM. They are meant to take punishment and have a voltage rating between ~4 V and up to around 26 V (a condition referred to as "double jump start")

I used my lab power supply to charge up the car battery in one of my cars - I also left one interior light on by accident which drained the battery almost to zero Volts too. Disconnecting it from the car and letting it sit brought the voltage up by itself and after that I had it charging on my lab power supply with a current limit of 3A and voltage set to 14V which worked flawlessly.
I also checked the battery with a professional battery tester afterwards which said that the internal resistance and cold cranking amps rating is still within specs so I was lucky I guess.
nerdywolfi A car battery trickle charger uses about the same voltage and current. Good job!
