Hi, everyone Welcome back Cody's lab
So I have here a 9-volt battery these things are very useful because they are small produce a high voltage and are easily
Able to connect to things I have it wrapped in tape because I'm not endorsing any particular product
But these are brand new batteries as you can see they're just over 9 volts if I switch this over to amps you can see
That it produces about point four amps of current
I've always wanted to do some experiments with these and so I ended up buying over 50 of them
I ought to be able to do something interesting with this for starters
I went ahead and hooked them all together in series and as you can see I've made a battery with over 500 volts
And the amperage is still the same because the resistance brings it down due to ohm's law now it's time for the experiments
Let's start off by arcing out the contacts and see how big of a spark we can make
The spark that I was able to generate is
Less than a few millimeters in length
It was actually quite disappointing, but it makes sense because direct current can't jump through air very well
But this bank of batteries is easily able light light bulbs
And I was actually surprised that it was able to light this complex
Fluorescent because because the actual discharge Tube requires many
Thousands of Volts to actually light up
Way more than I had here the reason these bulbs are able to light up using the current that comes out of the wall is
Because they contain a small
Transformer that takes the alternating current and steps up the voltage since direct current will not cause induction
I was kind of perplexed here
Until I tore the thing apart turns out these bulbs actually use rectifier diodes to convert [the] alternating current to direct
current which is then switched with transistor switches and
Turned back into alternating current to be stepped up through the transformer seems kind of weird way to do it
But obviously it works and using direct current actually remove as one step anyway
I got tired of this high voltage low amperage
So I think I'm going to go ahead and put the batteries together into parallel circuit, so that I have high amperage
Adding the batteries in series adds voltage adding them together in parallel adds amperage as you can see I managed to get 12 amps there
For half the Bank of batteries now
I had the whole thing wired together
Something must have shorted out so I decided to dismantle it and try again we using actual solder
So I'm not you know taping it together
so as you can see I got 12 batteries here put together and I managed to get 19 volts and
about three and a half amps
so
Parked car on a hill here. I'm gonna hook the battery and
Replace it with this homemade
Battery Which made of 9 volts
Use a wrench on [it]
You see I've already added some wires here. Just make this thing easier to connect
I think I think I'm most worried about is when the alternator kicks in and it actually starts putting power back
It might actually
Fry these little wires so the car might start and then immediately stop or start a fire. That's a possibility
Show off your safety precaution what's my safety percaution. Fire extinguisher. Oh, yeah, I do have a fire extinguisher. We're good
Not Sparker Arc good
Alright batteries in place that ought to hold
Least a little while, okay?
Let's see if the thing's actually making contact
Good enough ready something real started
No, good all right, so I went ahead and found us a little bit steeper of a hill
I don't think there was quite enough juice to get the fuel injectors and stuff running
So we're gonna go ahead and try this a little bit faster and see if it'll actually work this time
So you could add a off the park break in gear
Hey
Oh yeah, that shouldn't be on.
Okay, that might have been a problem last time
turn off the Ac alright, so
We got light. It's good. Let's go ahead and get rolling
Ok this is rolling much faster this time
There it is
We're running. Let's see if we can turn the lights on. We should be able to because now we got the alternator going
About that
Let's go ahead and take her home
So we made it back home safely. He's a bank of batteries worked Fairly well
Now if you think about it all they were doing is running the spark plugs and the fuel injectors
It wasn't actually turning over the engine that was
From rolling the car down the hill that actually got that working. So these batteries probably didn't even need to be this big
it looks like it melted the solder a little bit from the heat of
Running the alternator through it all in all it did actually a lot better than I thought it would
I will definitely be revisiting the battery projects
Sometime soon. I do have 50 of them still and they've got quite a bit of juice left in them
So if you guys got a good suggestion as to what I should do with them
Please let me know and I might even be willing to get some more of this video becomes quite popular
So I hope you guys enjoyed. I'll see you next time
