And all these years I was happily replacing my batteries .now I know how to fix them .thanks
+Shivansh Gupta Do not expect that all the batteries can be repaired this way. Some will work, other will not.
TechTronic9000 thanks for the info,but it would be fun to do this DIY if we are really going to replace the battery,whether this method works or not.Thanks again for the info.
I followed what you did here and salvaged three APC UPS ES 550 and one UPS ES 725 . All 4 units are back in operation. Thanks man. Live the tunes too 👍
+stevemichelle1203 I'm glad that you have found the video useful. Credits for the music go to www.joshwoodward.com/
Thanks a lot!! A headache was solved in 10 minutes. It took more to watch all the video 😂😂
A suggestion: As a creator, you can make a sticky post that will appear on top of the comments.
Here you can tell:
* The writing was deleted by CZcams
* I use distilled Water
* etc etc etc
Thank you for the ideea, I will do that!
Very nice video and the music fits very well.
A low-cost desulfator would be a nice addition to your process: you could add/remove water from the cells according to the desulfation boiling process, thus making sure your cells are properly filled.
Of course in case a battery is truly dead, we should keep in mind that fresh replacement batteries are quite cheap!
Thank you for the comment ! Yes a desulfation would be a great addition to restoration procedure but i don't want to waste to many resources and time. If the battery would not charge after adding water then it's time for a replacement. Credits for the music go to Josh Woodward (more info in video description).
Thank You - it's a very informative video in 2021 too! 👍😊
Glad it was helpful!
What you did exactly? Fixed the battery ?, I bought new battery already so it's mean I don't need to fix it like you did , or is anything else I should now , please help
Thank you so so much for this video.
Saved me a headache.
Glad it helped!
Thanks mate ur video really helped me to make my ups alive again....
Keep up the good work....😊
Hi there ! Thank you for your comment and appreciation.
Hey, I’m planning to restore my ups battery but it seems APC doesn't want people to do it, because it comes sealed and it's not easy to disassemble as one can see in your video. Any advice on cut the plastic to access the distilled water containers?
my apc 500 was not in use foe long time,now when i plug in the ac wire,it shows orange/yellow on battery light only.can u please help.Ur video is very informative.
Thanks a lot. I came to this video while looking for a solution for my PCM UPS which suddenly started occasionally turn itself off with an overload light shining. It confused the hell out of me because I have not changed anything in my hardware config and there's no way it can be overloaded. Thanks to your video, now I know that it might falsely report overload because of the bad battery. My UPS has worked fine for two years already, so maybe the battery has vented. What troubles me is that it doesn't show low battery level at all, battery indicator always shows full when the problem with overload happens. And it doesn't turn itself off immediately when left running on batteries. But the battery indicator itself should be fine - it has been running on batteries couple of times and the indicator was showing pretty accurate levels.
I'll test the battery as shown on your video and I hope that it will turn out to be battery fault, not UPS.
I also remembered how my father used to recover his lead acid batteries for his motorcycle - he was using freshly fallen snow instead of distilled water, and it worked just fine. I'm not sure, though that I should risk and use the snow for my UPS batteries :D
camelCased
Hi there ! Thanks for your appreciation ! From what you describe it seems indeed that the battery has vented and lost most of it's capacity. When venting the battery will charge fast and also discharge fast giving exactly the same behavior as you describe. Also take note of the battery placement inside the ups, if it's close to the main transformer it will overheat and dry out (this happens to a lot of UPS models). APC uses a plastic separator which keeps the heat away from the battery giving it a better an longer life. By the way fresh clean snow and / or rainwater is better than tap water as it's naturally distilled water. There are some minor contaminants from air pollution and possible ground contact but in an emergency or in a clean zone (forest, mountain etc.) it can be used.
When I opened the APC 950 the battery was dead and started to leak some oil when I caught it, I gave it for recycling and put it in CSB HR1234W or CSB GP1272 F2 which are just as compatible.
Probably the battery case cracked and that was acid/gel oozing out. It's rather common on the APC brand as they get very hot even on stand by so it dries up the battery and kills it.
@@TechTronic9000 Thanks but apc Is better from eaton because stop to work I change battery and Is all ok now.
Молодец👍👍👍
Все четко и без слов все понятно!!!
Very helpful video, quick question though, if I don't have the lead acid charger can I just charge directly from the UPS after filling the battery with water? TIA
darkjay263 Depending on the UPS model / type, it may be possible to charge the battery directly with it. This model of APC does charge the battery when it's OFF. Turing it on with the flat battery will only give errors. If you have access to a multimeter it's better to check if you have around 13.5-13.8 V at the battery terminals to be sure that the charging process is working.
After long use, the Sulfuric acid becomes weaker, along with the decrement of the water capacity(decrease of dilution).
So, I think, to recover a lead acid battery, there are two options:
1) to add some distilled water,
2) to add some Sulfuric acid.
Please focus something on the addition of sulfuric acid. I think adding Sulfuric acid will really help the situation!
I just need some information about which hybrid(type) of the acid is actually used, it's concentration, how much dangerous the process is...
Because, it is not possible to refill the battery with distilled water and expect it to work just as a new one(It will not be as efficient). It will just cause wastage of time and energy.
Thanks in advance! :)
If the battery is too old (used) then it's not economic to either add water or acid (dangerous). When the battery works in a hot environment it will vent water from the gel paste and become inert, adding water will mostly restore it.
True...
Thanks!
By the way, your video is the most neat and effective among the Sealed Lead Acid Battery Recovery videos out there!
Keep up the nice work! (y) :)
Thank you, I will do my best to do other useful guides, and the newer ones will also have voice over with more explanation :)
In my case, I overloaded my 4-5 year old UPS, and it made a trickling sound for 2-4 seconds and tripped off.
I just understood that something went wrong as the UPS didn't start at all after that... It was 4-5 months ago.
After 4-5 months of that incident I opened my UPS to find my 12V battery reading 2.54V and had almost idea about the complex circuitry!
I at first thought that my circuit burned due to that overloading, although I am not sure, but I now think that changing the battery may work! Any idea what might have happened?
Your UPS should have a circuit breaker, you should check that first.
I'm having the same issue with my XS 900. I'm having a trouble with the substance used. Is all distilled water deionized? if not, is it crucial and i can get by with regular distilled? if yes, what kind of store has deionized distilled water?
Thank you for the demonstration!
Distilled water and deionized water are the same thing. So whatever you mange to find is OK.
i have an apc Pro 1000 I did this and it holds a perfect charge
+John Miller Nice to hear that.
Thanks! Will have to try out, but what was the water level after pouring in the distilled water? should it touch the bottom of the holes? I've got an 12V 18AH/20HR battery that I want to resurrect :)
Water should be absorbed by the gel paste and not to be left extra otherwise it can boil and spill acid.
Good video, going to try this out
Thank you for your feedback. Let me know if it worked for you. Be sure to check first if the battery is deformed or cracked.
Is there a write up of what is happening? It isn't clear to me what the various lights mean and the voltages.
Sadly there was a full write up over the video did with the old CZcams captions which were deleted and disabled by CZcams so sadly lost the info. The lights are for load testing.
sir do you have an idea, why my UPS like that in your video has on line has no line, and the On-Battery is just blinking? what does it mean?
These APC units have a lot of faults, they have various capacitors that dry up and make some parts of the electronic to fail. If the battery is good I would inspect the capacitors.
thank you,It's very useful
I'm glad that it helped you !
A neat trick! My CS 500 just keeps flashing the yellow On Battery light rapidly as soon as I plug it in an outlet. The Power button does nothing except for dimming the flashing light a bit, doesnt respond to anything. This situation is not described in any guide I have googled up. Its a pretty old device so I took it apart completely, but none of the capacitors or other components look damaged. Any idea what could have gon wrong? Do you think that replacing all the (larger) capacitors is worth a shot?
The CS500 had an issues with a voltage regulator / resistance getting overheated and blowing out. Try to search from some "blackened" components.
I visually checked all the components, but will try my luck again, thanks for the tip.
I'm converting the same model but with outlets to lithium, it will be a 3s 12p battery with salvaged lg power tool cells. The cord will be removed and it will eventually get a solar panel and hooked to a DC to DC converter to a 3s bms on the batteries to charge but for testing I'll charge it on my imax b6. I'll also add some USB ports and a fan if it works decently.
You need a good BMS otherwise the UPS will just overcharge you Li-Ion cells.
You fill the battery with water and recharge it.
But after recharge, the battery is dry again ? You dont refill again it after recharge ?
You do not want to add to much water as this is a gel / wet (not flooded) battery. It need just a tiny amount to re-establish electrolyte conductivity when it's dried out. Adding to much water will make it boil, crack, vent and spill acid.
i can't understand why you dry out again the battery if the initial problem was the lack of water. If the battery is dried out, it should be dead again or am i missing something?
combinbain I'm not draining it, I'm verifying if all the added water was absorbed into the gel paste. If you put to much water the battery will boil and leak acid. So it's a safe measure to check that there is no remaining extra water.
Apa dedurizată și distilată sînt una și aceeași?
Mulțumesc pentru video!
Salut, sunt acelasi lucru, se pot folosi amandoua.
Am folosit apă distilată, dar am inundat celulele cu >10 ml / celulă, apoi mi-am amintit că ai menționat o cantitate mai mică :) .
Acumulatorul a început într-adevăr să funcționeze, dar generează foarte multe gaze, astfel încît capacele de cauciuc „zboară” la fiecare minut. După ce am pus panoul de plastic înapoi, le ține în loc, dar gaze oricum se aud ieșind periodic.
Temperatura acumulatorului nu crește față de cea a aerului (poate cu 2-3 grade), așa că îl exploatez pentru un Raspberry deocamdată.
Asta era un motiv pentru care nu se pune multa apa :)
Are these Batteries Gel or Agm? Im gonna try this too👍
It's kind of a gel type, that in some cases evaporates the water and dries out.
Hi, good video, y have a problem when i plug the ups, the “on batery light” turns on inmediately and the pwr button dont do nothing
It's a common fault for APC models after some age, usually it's traced to some dried up capacitors that need to be replaced. I have spend a lot of time trying to sort that out but it was too time consuming so ended up replacing it with another UPS. Another reason to drop using APC as most of my older units failed in the same way.
@@TechTronic9000 Heyman×
How long we will charge the battery? ( hours)
Eymard jay Pepito The battery should be charged for a minimum of 12 hours, recommended 24 hours. It also depends on your charger.
What liquid did you put on the battery?
Distilled or demineralised water.
Can I use RO/DI (reverse osmosis/deionized) water instead of distilled water?
Yes, that will work also.
can i charge the battery with variable power supply ??
if yes then what current and voltage should i set ?
+Tanmay Patil Yes, you can. Use 13.8 Volts and limit the current to 1/10 of the battery capacity (for a 7Ah battery use 0.7A current).
I have cs-650. When i powered it on it the "replace battery" is blinking red and the ups is beeping. I measured the voltage and its all fine when powered off and it does not drop when i power on. Can you pls help? :)
+Filip Koneski Take out the battery, use a car light bulb (55W or higher) to add a load and then measure the voltage and see how much will it drop. I believe that the battery is the culprit. Even when turning on the UPS the voltage drop may be too fast to detect on a voltage meter.
hey hi i have ups recently i have changed batteries for ups but its not giving me full backup time do you know any solution
Maybe the new batteries don't have the same capacity or the power draw is higher, also new batteries require at leas 12 hours of charging.
great work
Thank you !
I like the music. who it the band? Great video BTW.
Thank you, the music is from: www.joshwoodward.com/
one small question. after add distilled water, how many days battery are working good condition
+Veera Mani from when the video was uploaded till now the same battery still works.
+TechTronic9000 wow.. thanks sir. ur video is vrey nice. . and tomorrow I practically try then I will feedback. . thank you
+Veera Mani ok, let me know how it goes.
Veera Mai
nice video, I have the same type APC ups it is working on battery but when I turn off and remove the Main power supply complete from the wall it is start noise and the over load light turn on. after that I can't turn it on back. what I have to do disconnect battery and connect it again & need to press the on again. can u help me to find the problem?
thanks
If the UPS shows overload it may be from two causes. The main cause is not that the power supply exceed the UPS output, but the battery is not holding a charge properly. When you disconnect the UPS from the mains it switches to battery, and when the battery is old and weak the UPS may trigger the overload alarm instead of replace battery. Have you added water to cells, if yes leave the ups overnight to charge the battery. Also do a load test on the battery to see if it holds a charge.
Disconnecting meaning when I am not in use the UPS I turn off it and remove power cable from wall, but when I turn off the UPS and if I keep the mains power on there is no alarm or any sound, however I did't add any battery water and the UPS is near 10 years old now, I will try adding Battery water and do as you said & update you. however thanks you a fast reply.
nalaka perera Check also if the battery case is cracked or if it has swollen. If it has balloon or it is cracked do not add water as it will drip out acid. From what you describe i believe that the battery is dried up.
zangah I didn't find any cracked or balloon on the battery but when it shake I can hear the sound of battery water
nalaka perera It can only mean two things. Either someone already added water, second it's not water but some pieces of lead have corroded and flaked away which means that the battery is beyond repair. Try to open the vent caps and look inside with a flashlight, see if there are any loose metal particles that rattle inside.
well done video!
Thank you !
hello mine does random restart on pc and sometimes shut off completly i have to turn it on again i replaced the battery and still does this ?
+hesham fouad it probably has another problem, a poor contact is possible also.
Hello. are those liquid is normal water?
+Jaden Wu Hello, it's distilled water.
Awesome vid 👍
+stevemichelle1203 Thank you !
wen the batery making overload, overload, overload continuos what problem will be?
If you are not overloading the UPS by requesting too much power then the battery is failing.
What happens if you put too much water in the cells? I did the same thing as you but I filled them to the top.
It will overflow and spill, it is also possible that the battery will crack it's case.
could I just take some out or would that do more harm then good? Also, what voltage should I stop the discharge at?
TheSamchilders If you haven't charged it yet, you can leave it 2-3 days so that the water will be absorbed in the dried paste, then just remove all the water that comes out. You don't need to discharge as it will damage the battery even more. Just connect it to a charger and be sure that the voltage does not go over 13.5-13.8V.
I have already charged it once with the water in it. Should I still pour the rest out?
TheSamchilders In this case first fully discharge it to 10.5V, then remove the water.
I have an apc battery backup but I cannot plug more than one device to it. Once I plug in a second device it just starts beeping and depletes. But when its just one device it is fine. What could be my problem? I measure voltage and its 12 volts and it holds that voltage for a long time. But the moment I plug 2 device the voltage drops and jumps. not sure whats going on but is the the same as yours? will water help it?
It's possible that the second device to draw to much power. The APC C500 has a maximum output of 300W.
ment to reply to techtronic9000
TechTronic9000 i know for sure it is not drawing much power. I only plugged in like a 3w water pump and say a battery bank. I know that it is no where near the max wattage this ups battery can take. This one is an apc 550 so guessing it is similar. But not sure why it can't handle any second device. And all I can think about is can a the battery not be able to handle a certain amount of amps? like 3A and thats it? But maybe adding water will help?
It may be a a too old battery also inductive loads (electric motors/pumps) don't work well with computer UPS due to them needing pure sine-wave while the UPS has noting similar to it.
Also forgot to mention, try adding also a resistive load (a small 25W bulb). Some UPS's don't work properly with a minimum load.
So...you added water, then charged it. Then you tipped it over and no water drained out. Where did the water go?
Because UPS batteries are made to be non-spillable, they use a "gel" like acid, or a combination of materials that absorb and hold the acid without letting it drip out. Some UPS models like some APC types get very hot insider under regular usage like being always on standby. The UPS battery gets also hot and it's also charged, this will result in venting and will dry out. If you add some distilled water this will get reabsorbed and will make the battery perform better.
@@TechTronic9000 thanks for the explanation. I have a Nautilus Battery Pack:
www.canadiantire.ca/en/pdp/motomaster-nautilus-battery-pack-800-a-0111592p.html
that must have had a bad battery from day one, because despite it's 800CCA label it wouldn't start my 4cyl car after fully charging it when I first bought it. I chalked it up to the weather being too cold but then last fall took it on a road trip to run laptop and other stuff and its discharged warning horn went after 10 minutes. It's beyond the 12 month warranty and a new battery here is $150.
So, this morning I cracked open the Sealake 12v33ah battery from it and added probably 10oz of distilled water to it. I'm charging it now using the built in charger and after 15 minutes it reads 13.1v.
Planning on charging it as much as it will take then disconnecting the car battery and hooking this one up to see if it will start it. Interesting.
I have a APC 1500 va the backup battery works but the online led goes out. like if the voltage was low. can you help me. I've tried lowering but keeps on doing it. I think is dying
So it's show that the mains is off ? That may be a connection problem.
@@TechTronic9000 i also used this apc rs 1500, connection lost, means?
I have an RS 1500 with the same error, one of the batteries just melted.
what water will i use to change my water in my battery
Decriminalized or distilled
TechTronic9000 hey man.. can i do this battery fix on a apc es500? its a lead acid battery like that one... is it distilled watter should i use for the battery? .. its a 7.2ah
paulo159 Yes you can. Check first if the battery is not swollen or cracked. Only use distilled water, and be sure not to add to much as it will overfill and spill out when charging.
TechTronic9000 ive check it its not cracked. the battery voltage is 11volts.. the ups doesn't want to charge the battery it detects as dead.... distilled watter that i can buy at a grocery store?
paulo159 Any kind of distilled water should be OK (grocery, gas station, car parts, etc.). You will also need a charger able to supply 13-14 Volts to charge the battery so that the UPS will work again whit it (detect and charge it).
12V is to low and you should not exceed 14V. The charge curent should be 10-20% of the capacity. For a 10Ah batter it should be 1-2 amps maximum.
TechTronic9000 finally, someone smart that does not dump a gallon of water into a small battery LOL good work, be well my friend
thanks, would be more useful if we could read the meter.
Noted
hey man this is,nt working may be i have done some mistakes while following this video but can u please help me out it,s an emergency plese.
Maybe your battery is very old an it's not possible to restore it.
i don't have a charger can my ups charge my battery ??
+Shivam Sharma You can try, some UPS models do not charge the battery if it's voltage is too low.
some has a cold start future which is great for dropped batteries
where did you get that 12v A/C power cord?
Bull Shyte Are you reffering to the small battery changer ?
TechTronic9000 No, actually the white power cord that you plugged the lamp into at 15:06.
Bull Shyte That one is made by me. You need a C14 connector, a 3 wire cable and a outlet plug. Alternatively you can use a spare ups cable, you can cut the connector that goes to the PC PSU and install a normal / multiple plug.
... whenever i change from power line to battery it says that its empty wtf ??? i changed 12v battery with a new one still the same problem
It's possible that the ups output is overloaded or running almost at maximum load.
moj ups apc 500 nopstop cvili i piše replace battery i overload
so...... gooood
Thank you
ok ...tahnky
+احمد الملازم You are welcome !
thx I will try in my apc 1000
+azvoltage depending on the age of the batteries results may vary. Just be sure to check first if the battery is physically OK (no cracks, no deformations).
+TechTronic9000 ohhh ok I will check it's like 4 or 5 years old..
+azvoltage My battery was very old, 7-8 years old. It was almost a miracle that it has worked again, although the capacity will not be as new.
ok nice thanks!!!!!
You are welcome !
How about telking viewers what you're doing instaed of your favorite playlist SMDH
You are absolutely true, my newer videos all have voice over now. Thank you for the feedback.
putting water into these batteries *may* give a short life boost, but it won't be long, just buy new batteries and replace the dead one. it's really not worth stuffing around with it all.
John Douglas In general yes, but it also depends on the age and usage of the battery. The above UPS sit in a high temperature area and the battery vented all the electrolyte, leaving the internal paste dry. With water added the same battery is still working normal as i write this article. I'm sure that the battery capacity is decreased but it still keeps my small NAS and Router working for about 25 minutes.
if that's all you require, than no problemo.
What is in the bottle...hoplesd
Distilled water. Sadly this video has on screen captions, a function which CZcams removed so there is no explanation anymore.
can I use a small car battery with such a UPS?!
Yes it works, but car batteries do not like to be discharged too much. Also the charging in the APC UPS is very slow.
Oh, I won't, but I want my 10 min extra gaming time... :))
how much watter should I put, on the other videos they fill it to the cap, but I don't like that idea?!..
7ml, no more, no less?!..
+Ivan Bnv for a 7ah battery 5-7 ml. Adding too much is asking for trouble.
Exactly 7 ml, But still dead... 12.78V on the battery after the water, and still that value after 6 hours. 158V on the 220V, 13.6V while charging (still)...
p.s. Battery voltage suddenly dropped - 10.79V
Are you using the UPS to charge it ? After you add water you should charge it with a constant 13.8V voltage for 12-24 hours. 12.78V on a charger is to low. After sitting disconnected for at least 6 hours it should have 12.8V if 100% charged.
thankyou :)
+jaymar espiritu With pleasure !
+TechTronic9000 done doing this.. but ,,no luck!
+jaymar espiritu It means that the battery is faulty beyond recovery.
Anybody else watching this in 2022
I can definitely tell you that a lot of people are still watching this video in 2022 ;)
an informative video but ignorant music... what possessed you... better silence
trebao si imati rukavice da ti slina od baterije ne ošteti ruke
There is one "little" problem. By adding distilled water to the battery you won't help it. Because all the "sulfuric acid" is on the plates sulfated you end up with battery filled with water or more diluted electrolyte. Maybe if the battery off-gased a lot puting some H2O might help in the end but you have to get the plates clean of sulfation. Measuring voltage on terminals is one thing , put the battery under a proper load (discharge) and calculate the capacity , you'll see. It won't gain capacity ...This is not working. I have done it. ;) cheers
It really depends on the state of the battery, some batteries are impossible to recover, other may work again, of course a few years old battery revived with water will not work like new. For my above case the battery keep the ups working ~30 minutes with a small load (Router and NAS).
In another video with ups battery recovery i see that instead of distled water is used water with 30% sulfuric acid. Will make recovery stronger using acid not pure water or will make battery life shorter?
