Hi, I don't know why I've been killing my car battery so often. The car doesn't start anymore,
so I have to go and give it a boost again. So by now hopefully I've become an expert
I have some things to bring with me which include my super caps
which I have charged to around 14 volts, an extra 12 volt battery and
My meter, let's see if I can do it
again
This time the battery has discharged so far that absolutely nothing works. No lights nothing
I have to check and see how far the battery has depleted.
Okay, let me see how much juice is left in the battery
What?
F***
0.7?!
Probably my battery's dead. At this level, I can't connect my Super cap to this. This voltage will short my super cap running
I don't know like 500 amps through the wires. It's okay,
I'm gonna connect my puny battery to the big one using my alligator clips and watch the voltage too
And hopefully it will slowly raise the voltage to something decent.
Okay, here we go
Let's connect it up
[CONNECTS]
But the voltage jumps to 12 volts right away.
Well, it's slowly going down . What does it mean? Let me disconnect it again
No, the car battery charged four volts seems like
[SIGHS] You know, it doesn't inspire much confidence when your car battery voltage jumps up so easily
I have a feeling the car battery's dead
F***
huh, I'll leave it to be charged for a while and see what happens.
Maybe its so under charged that it jumps up easily. And while that's charging, let's look here. It seems like my
light was on...
But, I've never had problem with leaving lights on. I thought the car turns it off after a while
Okay, the car battery now is around 9 volts so not bad
It's coming up just that I don't know if it's good enough to start the car anymore, but you know what?
It means, it seems like I can connect my super caps to it easily without hopefully damaging anything
Let's see if I can jump-start the car. Okay, let's carefully connect the jumper cable to my super cap.
Careful
I don't want to short this thing
there we go
connect to positive
It might shove a lot of current into my tiny battery too...
Hopefully it's not too bad
Okay, let's watch the voltage
ready?
Okay
What happened? Seems like the super cap is discharged to some extent. It's charging back up with the puny battery
okay, I had charged the super cap to 14 volts, but
[QUALITY CONTENT] OH S***
CRAP!
What the f***?!
S***, What happened?
So my alligator clip wires just burned. But it seems like they can still work a little bit
Hopefully, my (CAR) battery is at 12 volts
If I disconnect the battery, it's slowly going down. I think my battery is no good anymore
I had charged my super cap to 14 volts, but I also have parallel resistors which
Slowly deplete the charge in it. In any case the super cap has enough charge in it like
It's around 13 volts
I'll connect it quickly and jump in and jump start the car
and hopefully it will start and then I disconnect everything
Ready, set, go!
[GRUNTS]
[DOOR SHUT]
Damn it nothing happened. What's the voltage?
5 volts damn it!, it just sucked the entire juice out of my super caps
and didn't start. The super cap is at 5 volts now slowly charging with my puny battery
through the broken alligator clips, damn it!
Well, it's charged now. But I wanna see if my super cap can actually deliver much current
[Strikes alligator clips against each other repetitively]
Not bad, eh? Maybe the connections are not too good
[Strikes again]
Ok, it seems like everything is charged to the same level around 12 volts.
Let's jump start again,
Ready...?
[Car engine rattles]
Damn it, not enough juice
But it's almost doing it
Okay, let it charge again
You know what?
I'm gonna directly connect the super cap to the battery lid so that
they reduce the line resistance as much as possible
Oops, I shorted something. Okay, super cap is directly connected and the battery voltage is now at
12 volts, let's jump start again
[Car Engine Rattles]
*RIP CAMERA*
Damn it!, the camera fell
[laughs maniacally]
Something smells here though. I think my alligator clip wires are
Burning further every time I try to jumpstart
Uhh, they still work.
I have a feeling that 12 volt doesn't quite cut it. I have to go bring my drill battery. 12 volt drill battery
and put it in series with this puny battery and hopefully raise the voltage to
15-16 volts, and probably that will jump start the car
here are the batteries
An engineer that has everything except the proper battery booster
Okay, I'm gonna put the drill battery in series with the puny battery
and the only thing that really limits the current into this is the resistance of the alligator clip wires
So hopefully the current is not too big
Okay, Let's carefully connect the (wires)..
As soon as the voltage reaches something decent
The wires are getting hot
[QUALITY CONTENT] S***!
Let's leave it. But as soon as I disconnected the voltage drops quickly, so it seems I don't have much time before everything burns
So I'm going to connect it and go run in and jump start and come back and disconnect everything
Ready, let the voltage go up first
Okay, go go go
Ready
Set
[RUNS AND GRUNTS] GO!
[ENGINE FINALLY STARTS]
[ALLIGATOR CLIPS PROCEED TO MELT]
[BLOWS] STOP STOP
[COUGHS]
S***!
Waa
[SIGHS]
Look at the wires. Well, they helped
Now the question is; Can the car battery get charged and stay charged?
I'll,
I'll let the car run for like 15 minutes and see what happens
Well the car is running for now
I have to leave it for another 10 minutes to see if the car battery gets charged
But if it's broken
Then I at least know how to jumpstart again using my ghetto setup and get it somewhere to get a new battery
You may ask why didn't I put a bunch of double-a batteries in series like I did before the problem
Is that if the car battery is actually dead then those double-a batteries won't be able to charge the car battery and the car
wouldn't start and I make much more smoke this way. Anyway, well, it's been running for fifteen minutes now
So if the car battery is not dead it should restart again, but I highly doubt it
Let's try it again
Prayer
[TRIES TO START]
[ACTUALLY STARTS]
It started. IT STARTED!
DAMN IT!!!
[QUALITY] IT F*****G STARTED!!!!
Agh. I don't have to buy a new battery. Let's try one more time
[TRIES TO START]
[CAR STARTS]
[LAUGHS MANIACALLY]
So, I guess the car battery was not dead it was somehow super discharged to close to 0, I've never seen those bad
I thought if it gets close to 0, the car battery dies and doesn't charge up anymore. But hey
It came back. Well, I'm guessing there might be some permanent damage, but it's still working
You know what third time is the charm it's been off for like two minutes now. Let's turn it on again
[TRIES TO START]
[CAR STARTS]
[LAUGHS] Hihihihihi
I guess those alligator clips didn't burn in vain.
I think I should really check something what did discharged the battery that far down?
Maybe something is leaking and drawing a lot of current when the car is off. Okay, I'm gonna measure the current from the battery
Via this clamp meter? I don't know if you can read backwards, but it's around 0.3/0.4 our baseline
and if I measure the current
its around 0.2 / 0.1
So maybe something is drawing a little bit around 0.1 / 0.2 amps which is not much to
Like kill the battery. It will take a long time to kill a battery
With maybe 0.1 or 0.2 amps of current
for example if this is a hundred amp hour battery with point one amp, it will take
A thousand hours to discharge this battery now
now I unlock the car and the current is zero
Which means that it's drawing around 0.3 / 0.4 amps compared to the baseline
I'm gonna turn on one of their ceiling lights and see how much current it draws with only one of them on its drawing
-0.4 which means from the baseline is around point 0.8 amps of current
So if I leave one of those lights on it could discharge the car battery much faster
So I think that's probably what happened. It seems like when the car is off
There is no significant current, discharging the battery
But I probably left these lights on and usually I go drive the next day
Which means that the car battery is not
Depleted much, but this time around we didn't drive the car for a couple of days which probably just killed the Battery
Yeah, don't forget to turn off all the light and everything in your car.
But the question is: Would it turn on again?
