Build a 48 Hour Backup Computer Power Supply - SYSTM

[ievideos]

The good bit starts at 12:00

[m35a2lover]

couldnt i take abunch of the same kind of batterys that come stalk in the ups maybe 5 or 10 and wire them all in parralell

[TheError404]

1. Average PC draws about 300 watts. UPS from battery would draw about 25 amps. using a 2 50Ah batterys you can get only 4 hours (or maybe even less if your PC is monster) :-(

2. UPSs are not designed for long operation under high load

gas generator 120v output around 210$ at pep boys use outside

[kreeplx]

That arc welding trick was really cool right next to the batteries and your face. Your lucky you didn't get a hydrogen flash with the arc so close.

[AxelTiger]

Just found my next hack fix :D

[TheCody061691]

Buy a Generator and save time...

[AxelTiger]

@TheCody061691

generators take time to start up, a UPS switches to the batteries as soon as the mains power cuts off. How fast can you start a generator?!

[DigiDavidex2]

the PC has crashed XD

[hilltop7]

why wouldnt you just use a dry cell.

[JohnEEADBL]

oops

sorry

got it in there x 2

:)

[JohnEEADBL]

Some of y'all need to turn the sound up; they did say to use a deep-discharge battery.

To "fix" their bad, 3 x 12v batteries in series = 36v diagram, connect 3 x 12v bat' in parallel properly, so they'll all charge:

Connect battery 1 positive (B1+) to B2+, then B2+ to B3+.

Connect B1- (negative) to B2-, then B2- to B3-.

Connect B1+ side to + terminal on UPS.

Connect B3- side to - terminal on UPS.

This will ensure B1 thru B3 all charge (but, at 1/3 rate of only 1 battery charging).

[Hammerhead786]

Why didn't they mention a smart charger. I have my batteries on a trickle that shuts off as soon as the battery is 100%... the dumb fukkkkks... 25 bucks at Walmart

[scottjop656]

Did anyone notice when he said "two batteries" at 5:50 he held 4 fingers up?

[TheVeisonchen]

asian eat fish ! and smart idea cames automactily

[CybershulDotCom]

This video is nonsense. A car battery is made for starting engines, not a constant high current drain. [talking from lots of experience with deep cycle batteries, inverters and related stuff]

[lyokofans]

lame

[wjz10595]

If you were to put a battery in a battery box, could you fill the rest of the box with baking soda to also neutralize any acid that exits from the battery? I noticed there was some room in the box you could have filled with baking soda.

[BBQTeach]

@wjz10595

Seeing as they filled the tray its sitting in I guess so, but the baking soda could get into the battery turning what w;oud be a minor acid leak into a death sentence for your battery...

[llVIU]

haha they don't even know the difference betwen series and paralel

and after all the safety measures I was expecting him to show up in a space suit

[TimTizzle]

omg i got so annoyed after the sponsor message (that feeled liek 5 min)

and directly after that a loooong talk about what can go wrong.. ugh 6 min in the vid and i cant take anymore

[Epsilon232]

Tucker what the f**k are you babbling about.

[gamaLaho]

This video is the resultant of two dumb-fucks who even don't know the difference between Series and Parallel circuitry; And 3000+ videos... these guys are shitting all over the YouTube.

[gerrysauto]

Use an AGM battery. I purchased two 55 ah units. I have a 15 amp automatic battery charger that I use. The total cost was 297 bucks. I can run for over 11 hours if needed. My 500 dollar plus UPS only would last 2 to 2.5 hours.

[mynith]

Difference between an American and a European show: We will not give all the warning notices except maybe just advising that you should know what you're doing... and we would at least get the wiring diagram right. They say it's parallel, but trust me, it isn't.

[mynith]

If you do have a trickle charger, you could still use it if you have a diode and a resistor to prevent overvoltage.

[johnchristian0131]

I got bored

[Me112233]

Gotta love that Godaddy ad . . . I'm dumping thier "service" as the arse hole that owns the thing likes to kill elephants. (No, I'm not kidding, the CEO killed an elephant and then bragged about it.)

[killazack121345]

@Me112233 killing elephants are hard nowadays, glad he was able to do it gratz to him

[PhantomAct]

am on 9th minute and am bored... how long do i need to skip to get to the real deal?

[computerpingu]

Asshole.... I burnt my face off....

[FinalSagacious]

I would did if it weren't for the ...  commercials

[Dsdennison]

Alright.... so you got the bigger battery hooked up.. So how do you calibrate the APC monitoring program or device so that it reads an accurate float time

[alicestar666]

batteries wired in series would yield 24v not 36 and they were wired in parallel. I think you need to google a bit before you comment.

[juggernautxtr]

@alicestar666

umm sorry but your wrong they were wired in series, positive to negative is series, parallel is pos to pos, neg to neg.

the diagram showed had three 12 volt batteries wired in series(pos to neg) yielding 36V.

[doxprodigy]

great video but rizwanarasheed is right. how did you miss that in the midst of that plethora of ritual disclaimers :)

[Pentium100MHz]

My UPS (2200VA) uses 4 (12V 17-20Ah) batteries in series (to get 48V) and 100Ah UPS-grade batteries would cost about the same as a generator. I guess I could use car batteries and put them outside but that would mean longer cables (at lest 4m) and probably too big voltage drop (UPS will think that the batteries are discharged too early). Limited 100% cycle count of car batteries is not a big problem unless long blackouts are very often and a UPS-grade battery only has ~200 100% cycles.

[ktfx5]

After 12 minutes of commercials and warnings it wasnt half bad!

[scottso241]

i live here in the philippine can do the same thing ? the electric here is 220

[inventorable]

@scottso241 Match the battery voltage in the UPS and you will be fine.

[n3rdbear]

The only stuff I learned from this video is the safety tips.

[LeoDemon]

do you think that builtin charger of small ups can eficently charge this bigger battery or bateries ? i am sure it cant... so whats the deal ?

[juggernautxtr]

@LeoDemon it can charge those batteries easily, the charger in those usp are actually just a normal run of the mill trickle charger. the only differance is the size of the battery and the time to take till full charge. a car battery fully dead might take a full 8 hours to reach capacity. but I very much doubt that one would really be able to do this. if your power is going out for more than a day i would suggest having a good generator around the house.

[v8nman]

Just so everyone knows, I did this to my ups, and last night it literally went up in flames last night. PLEASE BE CAREFUL!

[Endolaylith]

i would worry about the inverter overheating since they are only designed to run for the models designed time frame. i would add extra cooling to the inverter.

[carpdemon99]

i work with ups every day from 500 va until 600 000 va some system work on batteries in series

you can increase the capacity from the batteries just make sure they are stationary batteries because they are build different

car batteries deliver a high current for a short time

stationary batteries deliver a lower currant but for a much longer time

[moctezuma112]

wow... you might have saved my life..seriously. i'm doing a project using a car battery but was afraid of overcharging it. and i totally forgot that i can use my ups......

thank you so much...

[vicskyline9]

wait, windows xp compatable dx10?????

[SonySasuke]

LOL he's saying it can blow up and burn ur legs,house,etc. and the battery's brand is Die Hard

[Tab54o]

I had a 12 hour blackout when some shit was overloaded due to all the fat lazy fucks on my block running the AC. Fucked up thing was I was sweating my ass off the entire time and half of them still had power.

[XxJareebxX]

omfg fuck all theses ads

[seb85live]

WTF ! GET TO THE POINT !!! IVE WATCHED 5 MINUTE AND STILL GOT NO IDEA WHERE TO START !! U SPEAK TO MUCH AND UR NOT FUNNY AT ALL ! SO TEACH US HOW TO AND THATS IT ! NO STORY !

[sunnycheetah]

I do this routinely when we install solar panels here in south africa, we use a car battery as a buffer and a ups connected to that battery as our inverter. UPS with dead batteries is usually for sale at very low price so we just disable that annoying beeper and use the UPS as an inverter, which gives us a very clean sinus as well.

[pikachuthesquirtle]

how do you test if its a float charger or trickle charger?

[sirmasterpimp]

Use a multimeter to measure the current or look up the specs. I had a car battery hooked up to mine (had before a diode blew) and it would actually charge the battery, very slowly. I did however make sure I hooked up the battery to a external charger when discharged past 50% (deep cycle)

[ccraig412]

Put a voltage meter and check the reading... If it flickers like this: _-_-_-_-_-_... Then its a trickle. But just google it. ;-)

[pikachuthesquirtle]

oh... well i did google it, i couldn't find anything on it though. XD

[IRONMAIDENFAN2006]

10 min of damn talking get to the fucking point

[modmadmike2]

My UPS uses two VRLA batteries in SERIES fo 24 volts... I would either have to use a Luxury car battery or 2 car batteries lol

[thetechnician22]

13:47 Never do this unless you want a glowing explosion of melted wire and plastic mess! Really stupid.

[ajbutch123]

lol i just did this with my old power supply and used a tractor battery and yeah, we had 2 ft of snow on the ground... western north carolina

[alterbr33d]

13:51

[1981z28camaro]

I've been lucky, I've been running computers for years, using just a simple power bar, and have never fried any of my components. Sure I have had the power go out before being able to save something, but I save my work frequently so it's not a big deal.

but I may invest in one anyways, just to be safe than sorry.

[torolof]

fuk UTUBE now with 30 second commercials?

it's getting worse again!

[rizwanarasheed]

The wiring diagram at 21:08 is completely wrong!  They way its showing it would yield 36VDC because the batteries are wired in SERIES!!!

[hellatyteman13]

@rizwanarasheed Omg your right! haha.

[ajbutch123]

it is for charging dude.... lol listen to what they are saying!

[tobbenb]

They don't mention that you need a special charger in that case...

[shooterman619]

@rizwanarasheed if theyre in series you get more power right? so.. whats wrong?

[rizwanarasheed]

@shooterman619 : Well, power is power whether you get it from more voltage or from higher current. However if a circuit is designed to work from a 12V power source (such as the small gel battery in a typical home UPS) then in this circuit they have mistakenly chained 3 12V batteries in SERIES which would yield about 36V and that would fry the circuit components. The correct thing to do would have been to hook up those batteries in PARALLEL that would still yield 12V but would have more AMPeres.

[shooterman619]

@rizwanarasheed i thought parallel would give you more volts nvm then :p

[technoboyLT]

@rizwanarasheed This diagram was shown only for charging the batteries

[man0204]

@rizwanarasheed true.

[rizwanarasheed]

@422716 -- No mate you are wrong! If you go to 20:34 on the video they SAY that parallel is positive to positive and negative to negative which IS CORRECT by definition however the diagram shows positive to negative in the chain which is NOT correct based on their intended plan. Positive to negative is a series circuit which will STACK the voltaic piles causing a voltage increase. On a 12V UPS system, stacking 3 batteries like they show will make a 36V potential difference vs 12V that they need.

[crispybacon100]

the fabric of are lives

[jakedhpro]

an optima battery would be good for this, because they are fully sealed, and inert if they do break open and spill, plus with a yellow or blue top deep cycle would run it at least twice as long, because a basic car battery is designed to have large amp draw for a very short amount of time ( such as starting your engine) and does not do well with low amp draw ( like using it to power a computer through an inverter) but this is what marine or rv batteries are designed to do, and it is much safer.

[xplodermin]

yeah,, put car battery to ups,, it will provide longer up time, but i would never charge those with ups. my apc smart-ups 620 burnt while charging two 15Ah SLA-s ( stock was one 12Ah )!!!

[jacobthebluetoon1]

i use a 13 Volt Battery to power my Tv And DvD Player My Power Might Go Out Cause there Is A T-Storm With Power Full Lightining its Actaly Purple

Fuck The Power Just

[jacobthebluetoon1]

Power Outtage In Pinellaspark:This Account Needs To Reboot

[inachu]

They did not show this working with a computer being powered so this video is TOTAL FAIL.

[ccraig412]

put batterys in container outside and run wires inside. haha

[selulancie]

DIEHARD battery lol

[ae69ae69]

wtf commercials on youtube?

[77robinhood77]

someone has to pay their salary duh!

[sovietlemon]

theyre partners so they get paid for making videos, duh!

[77robinhood77]

obviously u dont know what sponsoring is

[sovietlemon]

what? i obviosly know what sponsoring is, they get paid to advertise the companies basically. but partners get paid to make videos, get comments ratings and subscribers. thats why most videos ask you to do this.

[mickhick95]

i h8 them 2

i thought youtube would never get invaded by comerials but now there is no end to windex

[dwoodsky]

@ae69ae69 costs money for long vids, costs money for carbatteries too, costs money to spend all ur time doing hacks and reviews

[TheAnigai]

@ae69ae69 i know, its bullshit. now im actually sick of hem appearing automatically >:(

[Ragrog105]

This is the fast track to really mess things up. This entire procedure should have took less than 5 minutes.

[endsofuniverse]

Thisvideo is great.......

[mattkoser]

The schematic DOES show the batteries wired in series. This would add the voltage of the batteries together. For instance, in this schematic, three 12 volt batteries wired in series would produce 36 volts. Putting 36 volts into your UPS would probably instantly fry the circuitry.

[MR2Di4]

Having worked for a telco, using 48VDC battery backup systems, I concur that the multiple-battery schematic is a series circuit. This is a disappointing video with too much yakking and too many ads, but much worse is the display of incorrect electrical theory and application. Incidentally the welding thing is possible as well, but only with the batteries wired in series, NOT parallel.

[arcer63]

is it just me? or are those batteries in the diagram in series? is that a connector that I haven't seen before? that is going to cause some major problems if they are...

[WelschVideo]

WTF at 17:40, does the person have no mouth? lol

[kayyouman]

I saw those spiders..lol
