what kind of damage could we do with a few of these?

Re: oooo nice!
You can use several of them as car battery replacement. Spot welding maybe...Comment

Re: oooo nice!
i was actually thinking about maybe using them as the primary source in a coil-gun.
but the price needs to come down a lot first.
5 of those would give me a 5KA load-dump!!!!!!!!
you could also use one to prime a directional emp cannon.
(not that i would of course
)

Re: oooo nice!
Its only rated at 2.7 volts . Still if you put a bunch togher you could use them as a battery and run a car off them .Comment

Re: oooo nice!
amps over volts anyday when your after a bang!
volts give you a bright flash and maybe a burst of x-rays, but amps give you molten metal!

Re: oooo nice!
"Nanocarbon graphene" LOL.
If they lie about that, I wonder if the capacitance rating is actually correct?
You can get some good ultracapacitors from surplus sites like Elec Goldmine.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search.Comment

Re: oooo nice!
I just wounder if this is for real , a 5000 f cap in what looks like a D battery .Comment

Re: oooo nice!
if you look at the foto's,
that "D cell" looks more like a 500ml beer can or larger!

Re: oooo nice!
Even in a budwiser size can its hard to believe putting a 5000 f cap in that space . This is more the kind of cap I am usted to seeing .

Re: oooo nice!
oh it's doable all right,
but it's not gonna discharge in a burst - atleast not without some damage.
datasheet says the charge time for 5000Farad is 10seconds to 10min's (maybe over the temp range)
and the ESR is .23
so they have the capacity, but speed wise they are more like a battery.Comment

Re: oooo nice!
IIRC, graphene was discovered not that long ago. I think it was about a year ago when someone showed me a video that mentioned the possibility of huge supercapacitors based on graphene. So maybe they are finally here. Pretty cool tech, IMO.
Electric go-carts, anyone?
Enough of these in series/parallel should give you the same results as lead-acid batteries. The added advantage is that you can deep-cycle discharge them without issue.Comment

Re: oooo nice!
you could re-charge your electric car in 10 seconds.
the only 2 problems are:
1: it would probably cost over 10,000$ for the "battery" pack.
2: you would need to hook it up to the local grid to get the current.
having said that, the packs from honda and toyota are so expensive that it may be feasable.
you need 200v minimum.
so about 70 caps - i wonder how much space that would take up.Comment

Re: oooo nice!
If each cap is about the size of a 330 mL soda can... a standard pack has 12... so 6 packs (72 cans). That's maybe a bit bigger than the size of a gas tank? (or not? - I'm not that much of a car person)
Even if the "battery pack" is as expensive as you said, I still think it would be worthwhile as long as that minimum 1 million number of charge cycles holds true. I doubt any regular battery can come close to this figure.Comment

Hi,
I have a Lenovo IdeaPad 3 15IAU7 that suffered water damage. It doesn't turn on (white power light flashes when on button pressed), and the amber light flashes when plugged in.
Symptoms:- Short detected – sparks appear when touching the charging port connection with board with a metal (even a multimeter probe).
- Visible damage – after cleaning corrosion, I found 4 possibly burnt memory chips near PC3165, labeled UD5, UD6, UD7, and UD8.
What are my next steps to diagnose and possibly repair it without replacing the entire board? Any guidance would be greatly... -
Hello freind i have hp elitebook 725 g3 White liquide damage
after cleaning the board i find à damage resistor white no value i test it not reading in multimeter
could some one tell me the value of this resistor
Thank you

Hi. Recently serviced a damaged A1466 Macbook Air. Thought to post the issues and resolution for each.
Macbook AIR Model A1466 Diagnostic 09-01-2021
Issue: Liquid damaged (beer spill) Macbook AIR will not power up.
Problems & Resolutions
1) Attached Apple magsafe power adapter. No green / no orange light. This confirms the absence of the PP3V42_G3H voltage rail. The PP3V42_G3H rail is the primary voltage rail necessary to communicate with the magsafe power adapter to report the green or orange light status to the end user....09-01-2021, 09:31 AM -
Hello, i got an HP EliteBook 840 G8 that has water damage, and i found this component has damage on it U60600. What is that component? I have schematics and boardview and the par no is:
SINERGY_SYV128RAC_QFN_20P i cannot fount it anywhere. Is this component have some other name?
Here is schematics + boardview... -
Hey everyone,
Had a MacBook pro 13" 2018 (A1989) come in for liquid damage. The only liquid damage was all around UB400. It was most likely soda, so there wasn't that much corrosion. I reflowed the UB400 and the QB chips with some flux, and replaced the caps/resistors that were in bad shape. Seemed to be working fine at first, but the next day when testing it again, the laptop charges and boots fine, the CPU would overheat, and U7210 would get to 70 degrees Celsius as well. I'm testing with only screen and battery connected at this point.
I can't figure out how...
