[@davepost7675]

Anyone watching this should note that the battery pack he removed from the UPS has two 12v batteries hooked up in PARALLEL This results in a 12V battery with twice the power of a single battery. This means using a single car battery would work just fine. However, if they were connected in SERIES, it would result in a 24V battery would probably means one would need two car batteries hooked up series to work in this UPS. (BTW, my UPS' battery just died and it is hooked up in series, so, sucks to be me).

[@Not_Sure-2020]

The smaller UPS units like this are often not designed for such a large battery. If you drain the battery to any depth regularly, you could easily overwork the charger and that could cause premature damage to the UPS and potentially overheating. As @Old Fhart mentioned, a deep cycle marine battery would be a much better choice than a car battery due to it's discharge characteristics.

[@reykonhimitsu7446]

Add cooling Fan for UPS...

[@epicdeuce]

I don't know why everyone is complaining. Just be sure to oversize your UPS for what you're doing, when in doubt go bigger (if you have a 500w applciation get a 1000w UPS) The transformers in 1000w + UPS are huge. Put a fan on it and you're good to go.

Thank you! I used this video to save a dead car battery which wouldn't charge because the voltage was below 9V.

So thank you again for taking the time to make this. Cheers!

Hey Guys. I just wanted to tell you it still working in my house since 2 years, the full charging time is about 2 days. It will be good for you if the electricity go down one or 2 days per week. But in all cases you should use a good brand ups with a good cooling system inside it. I will make a video to show you how it works in my house.

Sweet. I have an old sealed deep cycle marine battery that was in its golden years of its life. Found a 600w ups today that was missing its battery today at goodwill for 4 dollars. Replacement tiny battery was 30 bucks. The one I have is already-paid-for bucks. No heavy computer usage. Just using it to keep a security camera system alive during occasional power outages. Thanks for the vinidication that its not a terrible idea.

[@renekenshin6573]

I won't advise that upgrade if ac power in your home gets cut off frequently, it means the battery would be putting out charge faster than it gets in. That is because the built-in charger is not meant for higher capacity than what it's rated for. If the battery keeps getting discharged most of the time, and not being able to get charged at maximum or bulk charge at least once a week, the battery will get sulfated.

[@notyoung]

Use golf cart batteries. Two 6 volt, 210AH batteries in series for 12 volts will run that inverter for a couple of days (1260 watt hours to 50% discharge, even more to 80% discharge).

[@electronicshelpcare]

Great!!, what i was looking for and excellently explained for people like me, newbie in the electronics, thanks

[@vishva8kumara]

But you don't need that thick of wires to connect to the battery. This inverter is not going to pull a lot of Amps. One cable is enough no matter what big a battery you are going to hook up to this. Believe me.

[@tomegun2]

Don't use a car battery, it is not designed for extended time moderate load (drain). Use a deep cycle Marine battery. They are designed for a long time discharge like an electric boat motor. It will give you much better service. They are more expensive but may operate a 1500VA UPS for 24 Hrs.

[@dacianchronolog4104]

I just need something like a battery I don't need to replace 3-9 months because it's off-the-shelf... Car battery would be fine. If you where running an OLD TUBE Radio. Then yes. Cranking Amperage is what really matters.

[@denisfortier9716]

and dont expect the trickle charger inside the ups being able to recharge a deep cycle Marine battery. You will have to recharge with a standard charger. Many people dont understand the concept of power which is the amount of energy over time so if you dont exceed the capacity of the UPS in watts, you will be OK, you will just increase the amount of time you will be able to use the UPS with a deep cycle battery. But you have to take responsibility to recharge it by any other mean.

You must use a golf cart battery. Car batteries are sprint runners good for a quick short hard push of current. Golf cart batteries are marathon runners, good for a long time push of current. You cannot run a car battery down below 80% multiple times, it ruins them. Golf cart bats can be drained down much further without ruining them.

[@SevenSixTwo2012]

The traditional lead-acid car batteries like the one shown here emit toxic gasses as they charge and should not be kept inside. These gasses can also start a fire / explode if in contact with a spark or flame. If you really need this, buy a car battery that doesn't off-gas, like an AGM battery. Also, a deep cycle AGM marine battery would be best suited for this application.

[@katkatthecat]

Giving it high amperage will make it off-gas, the 700mA (0.7A) is like having a trickle charger on the battery, plus float charging is required to prevent sulphating. When drained deeply, I use my 8A DuraLast charger then let the APC finish it.

[@SevenSixTwo2012]

@@katkatthecat Be it as it may, he used the wrong type of battery. Anything kept indoors requires a SEALED battery, like an AGM type. This is why every UPS has a sealed battery inside of it right from the factory. Mistakes and defects happen and they can sometimes be fatal, so why take a chance just to save $30?

Rather than fucking up the unit (At that point may as well cut off the plastic housing for the battery), I just got a couple pieces of mains wiring, black and brown, stripped twisted and tinned 1 cm on one end, which goes into one side of the spade plugs, holding on by friction, and the other end striped a bit more and wrapped in a ring around the battery terminals, tinned also at the point the ring closes to avoid it unwrapping.

Us a car charger against a lithium car battery, and use the battery to power only 12-volt devices, for emergency power needs. Losses are now near zero, and the Lithium car battery will not sag voltage during its discharge cycle. This is a secret, don’t tell anybody...

[@jbnrusnya_should_be_punished]

Why bother with UPS with internal battery when there were UPSs with external connection in 2016? I bought a Luxeon 12v UPS with sinus and connected a car battery. All went good till 2019 when my 60Ah Energizer battery lost 50-70% of it's capacity... So car battery is not a good option. Now I'm looking for other battery types, which is able to work with such UPS and remain their capacity longer. LiOn is not an option since it has wrong high charge level (4.2*3 is much lower then UPS will try to charge SLA battery - 13.6v).

[@ericewaldklaver]

[@Twobeers1]

How much did the vacuum cost?

[@Aranimda]

An UPS battery is designed to be drained empty and recharged. A car battery is not and should not be used for more than 20% of its capacity. So, using a car battery for an UPS is far from ideal and may quickly age the battery.

[@davetheitguy4516]

Actually, most UPS systems use wet cell lead acid batteries, which are the same as what car batteries are. The UPS batteries are not designed to actually run for extended periods of time. They're designed to get you through short power outages or to give you a few minutes to get your computer system shut down properly. It's just as bad to let standard UPS batteries completely drain as it is for a car battery. There are some very high-end UPS systems that are used in mission-critical applications that have deep-cycle batteries that won't suffer damage if completely drained. The UPS in this video (and any UPS you get from a consumer electronics store) will be standard lead-acid wet-cell batteries.

[@rcxb1]

That's not true. The SLA batteries in UPSes are NOT deep cycle batteries at all. They are just as vulnerable as car batteries. That's why the circuitry in UPSes will SHUT OFF and drop the load when the battery voltage falls to 10V. The real problem is that these low end UPSes don't have fans and depend on the low power of their batteries to limit runtime. Use a huge external battery and the electronics will get hot, possibly starting a fire. Your house costs far more than a decent UPS with external battery connectors.

[@manorenjreghunathan912]

To save cost, some low cost UPS are using autotransformer configuration for charging/ stepping up voltage. In such UPS there is a risk of shock hazard if we touch battery terminal as the isolation is not done. They make inverter body out of plastic and prevents accidental touch of battery terminal. Idea is good, charging solution can even be using a solar charger. I agree that automotive battery is not designed for UPS/ inverter usage

[@TonyQKing]

Hey - Why don't you run your motorcycle on the UPS? All you need is a very long extension cord! Just make sure it doesn't accidentally wrap around your neck - or you will end up like Isadora Duncan.

[@TonyQKing]

No! Learn to WALK! Or use a bicycle.

[@navibean1635]

No: Just use a long extension cord. :-)

me siento como un burro...la ups tenia 2 baterias de 12 volt en serie a la salida, o sea carga 24 volts.....y le conecto 12 a esa entrada...y funciona????? que pasa con el inversor... alguien puede explicar en español¿¿¿¿¿¿

[@martinfranco1517]

Debe estar loco jajaja

[@OS-id7pf]

Hay algunas baterias de ese modelo a 24 v aunque no es conveniente hacer esto a la ups los componentes sufren gran deterioro por el calor producido

The electronics of a UPS are designed to work for a short period only

great tutorial, i followed it today, but i hit a big wall unfortunately because i found that my UPS has its two batteries connected in series not in parallel like in ur UPS so the car battery i bought today(12v) didnt power my UPS which needs 24v, im thinking about getting a dc-dc boost converter which can increase the voltage from 12 to 24v, what do u think about that? do u have any other solution idea ? thank you

[@IDEA18-NEW]

+abcanw I'm not sure i have a right solution for this. But i would buy another car battery to make 24v

[@Mindful2222]

+Video One English did that and it worked finally :D

i like this broo. great

[@SuperCptblood]

this will not last.SMF ( small internal battery systems) battery system inverters are designed for 5 to 10 minute backups, hence small heatsinks and no fans.If you increase the battery capasity from say 7Ah to 100ah, ups will theoretically run for 100Minutes+ but what about the heat produced?The transformer,mosfets surely will run out of thermal specs.And what about the charger which was designed for 7ah battery? 0.7amp charger for 100 ah car battery? It wil take about 30 days to charge the battery.

komputer saya ada 16 pcberikut monitor, speaker aktif, lampu, ada kulkas, dispenser, mesin air dan kipas 6 unit, klu pakai ups harus yang berapa? aki berapa ampare, dan bertahan berapa menit, mohon penjelasannya..

what is the flow of ampere from computer ups while charging the battery.

[@MrTantalust]

"what is the flow of ampere from computer ups while charging the battery." Good question.

[@arunvishwakarma3510]

not for harm computer and usi se charged ho jayega

[@navibean1635]

Yeah buddy! I charged my jayega, and now I just need a Corona & lime.

[@darlingtonmukotami8300]

Let's hope it will work for me

[@xakepp35]

2:26 Oh, that twist wire joint.. Seems you dont know what soldering iron is :-) Cannot you just unsolder that thin red/black wires from PCB, and solder your new thicker ones? Twist contact would will oxidize with time, increase resistance, would lead to energy loss, could heat up and is unsafe! Dislike for such unprofessional and dangerous modification!

[@NZ2Pepper]

Totally agree. This is a fire hazard! And that awful music.....

[@TheDaben]

I'm just here for the music...
