Laptop battery reconditioning, Battery repairing of Laptop.
This video shows how to re-use your exhausted laptop battery with the help of old battery of laptop. I have shown replacement of dead cells (Li-ion batteries) of the exhausted battery with the proper Li-ion cells (3.7 V rechargeable batteries). I have successfully replaced the old batteries and now it is working fine and giving me the backup of 2 hrs approximately..
Thanks for watching my video.

Excellent video! Thank you for the instructions!
The selection Jingle Bells for a technical video cracked me up.
Excellent lesson. Thanks

Nice Video! Excuse me for the intrusion, I would appreciate your thoughts. Have you researched - Lammywalness Trendy Trade Guide (should be on google have a look)? It is a great exclusive guide for learning how to recondition batteries at home without the headache. Ive heard some awesome things about it and my best friend Jordan at very last got astronomical success with it.
Not certain about the points made but ,if anyone else wants to discover how to recondition battery try Battery Recovery Tactics ( battery.RecoveryTactics.com ) ? Ive heard some pretty good things about it and my cousin got great success with it.
Thank you for taking the time to show us.

Even after full charged ( auto cutoff green light turned on) as shown in video, why it is showing 73% when checked in laptop. It means one of the 4 batteries u did not change is gone. U checked 2 batteries in parallel at a time, obviously it won't show if one in 2 parallel connected batteries is bad. Best is to test each battery seperately.
Yes middle battery not both are damage
Yes, you're right, I was also thinking about this issue, when he was measuring voltage..

Oh it's fully charged, yes, one of the other 4 batteries is faulty... 😳
I'm from Malaysia... and I got a lot of knowledge from Indians, these Indians are all wise and intelligent
Because of you I managed to salvage a bunch of 18650 batteries that would go to waste because the computer was broken. Thank you so much! I can now reuse the 18650s🥳
Really good for a person not finding new battery in the market easily or no budget for a new one. It will bring hope for him/her to revive his/her laptop.
Explanations and the video are very very clear.The demo. Is also very good. Thanks.
I was hesitant to solder a battery. I copied what you did and it worked fine. Thanks!!
Thank you sir, after watching 3 postings how to repair laptop batteries, yours was the best. Very clear instructions presented in an easy to understand step by step DYI. Please keep up te good work.
hello! thanks for you learning process, for your help i like your Ideas. Greetings from Venezuela
Brilliant! Very clear instructions. Thankyou!
You're really good. Thanks for the idea. I can now recondition my laptop battery
Thanks a lot. You are very clear in your instructions, and super understandable.
Must be Christmas because Im hearing Jingle Bells 🤣 so random to put that song in but interesting video😅
This guy is real. his works, very real. Good job
Thanks and my pleasure..
Absolutely amazing, only method that really works, thanks
Thanks : 17 Euros by myself , complete battery cost : 70 euros , thank U very much
Pls reply to my comment about being unable to fit the soldered pack back due to solder bumps. I think thats why they do strip resistance welding.
THIS IS USEFUL FOR US THANKS FOR THE DEMONSTRATION .

Very cool video! Down and easy! Thank you very much for sharing your knowledge!
Thank you so much, without knowing I had changed two of my systems with new battery. Not any more
Superb video showing how to open up a laptop battery, test the cells and replace the bad ones. I would have loved to see troubleshooting and repair of battery circuit as well.

try Saankramer Electronic Magazine System (just google it ) ? Ive heard some super things about it and my friend got great results with it.
Thank you for the educational help on rebuilding laptop battery
Well done sir! Very clear and practical.I guess your logic is that you save money from buying a new "battery" pack, so you can buy more things for yourself and your family at Christmas. Smart, innovative man!
Damn he even put it back in one piece. Worst case scenario I will do it as you my good sir.
THanks pare ! ure the man :)
I'm unable to do saldering
saved my money & day... and I was searching for Hp battery only :) thanks
hi this is ijaz , i like ur video, i have 3 batteries of my laptop, now i'll try to repair myself, thankx for this
Your laziness?
Love the Christmas music

Excellent video! Thank you for the instructions.
I love your English
Hello, just came back from the workshop after following the steps in you video and hey presto nice fully charged battery. In my case there was a badly soldered wire which was loose on opening which had the effect of reducing the top voltage to 8v also although all the cells were ok one was adrift from its welded tie reducing the capacity. Fixed both and now a nice big smile. Thanks for the inspiration to give it a try.
Great to here. Pleasure is all mine. Thanks
@@innovativeideas but mostly, the defective one, is the small circuit, inside the battery pack! lol
Thank you very much. I have no idea these could pull
Wow superb sir , excellent and innovative idea thank you for sharing the valuable information
I believe some laptop battery packs will self-destruct if you remove a pair of cells or cut off the voltage to the controller board in the pack. Thus when the cells are replaced, the pack will refuse to work, and laptop will not recognize it. This is done to stop tampering of the sort you see in the video. I believe if you maintain the voltage when replacing, by using an external power source, this barrier can be circumvented
.
You are correct. You have to do this very carefully because once tampered, it will even refuse to detect same battery packs.
You are correct - mine self-destructed (by burning out a PCB track) when I replaced two middle cells. I had separated all the cells to test them separatedly and I did not realise that the pack memory chip (a BQ20Z75) has the ability to destroy the circuit if its senses that the battery pack has been interfered with !

Have you found any solution to it?
Thanks, but I wasn't keen on seasonal music! The most important and worrying thing, however, is that you played the music over the soldering. It needs to be stressed that lithium batteries should not be overheated by excessive use of a soldering iron. Best wishes from London UK.
Ok
Cool Idea. I bought the wrong battery for a Laptop and didn't return it in time. I just popped it open and now I'm using the 6 3.7 volt batteries in some spotlights and headlamps I own.
exellent video! thank you i will try to make more batteries for my laptop
This laptop battery is the best quality, I also made one power bank by using the laptop battery.

I'm trying to understand your thought process.
thank you so much for the instructions!
the music kept me watching. thanks for sharing
Excellent!!!
Wow, you are amazing bro. May I know where is your service center so that I can get my battery to get it fixed.
Dear sir, many, many thanks for your very productive project. I will now be able to use at-lease once the non-working pack. regards, aftab ahmed. London
Super bro and your English are also nice ❤️
Thanks. Mine looked almost identical on the outside, except the connector is centered (HP Pavilion dv6700). It was much harder to open since the plastic was apparently melt-welded at the seams, so had to cut & break the plastic to get it apart. The batteries were also glued inside the case. Otherwise the six 18650 batteries were welded together the same and the 2 center ones were also reading no charge. Perhaps the middle ones die because they get hotter.
Is repairing battery is as new battery?
@@abdulnafay72
No, a new battery pack should be better if the cells are from a quality manufacturer (ex. Panasonic). Been a while, but I recall my repair worked, but the case got a bit mangled from the effort. I ran across a new battery pack on ebay or Amazon for ~$20 USD so bought one. Previously, a new pack cost $150 which wasn't justified for an older laptop PC. I recovered the good 18650 batteries and use them in flashlights now (plus some from other packs). Many people say they are still good-as-new if they charge to 4.2 VDC, but seems some of them do so but don't last long in the flashlight before needing recharge though haven't done new vs old comparisons. People use used 18650 batteries for many things, including rigging up backs for e-bikes and e-scooters (many youtubes). A Tesla Model S uses ~7000 of them (not easily recovered or swapped).
@@williamgrissom9022 I am getting the battery repaired from the shop it would cost me around 10$ and if I will get new original battery it will cost me around 35$.
@@williamgrissom9022 If good quality cells are used then it is as new battery?
@@abdulnafay72 I would risk the $10 repair. Worst-case, you will have to recharge more often, but I plug in my laptop to a wall outlet whenever I can regardless.
Nice video!!!
I tried this to my laptop's battery and I would like to ask you if the new cells must have the same capacity with the older because after I did that with higher capacity cells(I replaced them all
),battery doesn't charge even though it recognizes it normally.
Yes. Must be exactly the same with everything because the circuit will never recognize
Or the circuit must be restarted before connect them with batteries
Still you have to reset the mcu & eeprom counters. So you need debugging tool softaware and hardware. Forget about your accu. Go buy new one.
thank you for explaining ♥️
gracias, buen video y una explicación clara
thanks
bro
Ok
Today is Christmas and i watched this video . Jesus is with me.
Stay blessed. Thanks
Fantastic video bro. Helpful . Saved at least 4K for me.
Nice vid man, done perfectly
Great video but I have a question wouldn't it be safer to replace all six batteries at once because you don't know how many cycles the old/new batteries have so the capacity would be different thus potentially causing issues?
it would be better.
cells are cheap,so if u r doing this do a complete replace
@@newyork9453 Please guide from where cells can be purchased. Thanks in advance
@@KULDEEPSINGH-ok7yt These are called 18650 lithium cells,easily u can order from any online shop or from local electric store.
Avoid buying chinese versions
Panasonic,LG and Sony are great
and U can buy versions with high amp(u can ask from seller they guid you)and make your battry last longer
@@newyork9453 I would also recommend buying cells with solder tabs already installed. You aren't supposed to solder directly to the battery terminals (heat can cause cell to explode + they don't make for good solder joints. Solder won't want to stick to them). The solder tabs are tack welded usually which requires special equipment.
So look for ones with solder tabs when you go to buy the cells. It will save you a lot of trouble. ;)
If the power is completely cut off from the bms chip, it will die and you will not be able to turn it on again
I want to know about repair of the keyboard of this version HP pavilion g4 laptop.
Jingle bell waala music pasand aaya sir!!!!
vedio k starting me jo music hy uska name kia hy?
we're the same laptop we use (G4-1318tx) Thanks for this video, have another idea!
If these replaced cells have much defferent internal resistance and capacity than other cells then the battery will not work for long.
Is there required amperage for laptops?
i was wondering about this
it means replacing all battery cells with same mah will be better?
Repair is the best word, recondition is not. Battery conditiong is accomplished by depleting and recharging individual cells so the battery controller does not go into "safe mode".
Thank you very much, for this recording * * * * *
This video is a savior man
Thanks!!!
That’s interesting! Even though the good-condition cells’ voltage are not same , you combine them. Aren’t they supposed to be the same voltage?
In parallel yes, in series no, as long as the voltage is in a safe range and you put it on a charge. The BMS deals with balancing all the cells, but it doesn't hurt to make them similar in voltage.
where Do I get the replacement batteries ? Good work, namaste !
Link is given below video. These are lithium ion cells known as
Li-ion batteries. Thanks
These batteries are also available in any electronic cigarette or VAPE store
Thank you good man! Very helpful!!!!
Great video! Thank you!
Christmas music?
You teach technically, nice... All other videos showing uninstalling battery driver are foolish..
This has nothing to do with drivers... those are software...
Thanks for your demostration .
This method only works in Christmas so do it before it gets patched
hahaah
There are thousand of videos in youtube about changing the cells of a laptop battery, but i didn't find the video that " How to repair the circuit of Laptop's Battery?
Dear Sir i request to you that please tell me the name of a machine that can identify all problems in Laptop battery Even in Circuit or Cells.
Thanks alot for sharing your experience with us
please wait for some days. I will work for that.. (Circuit Repairing of battery.) Thanks
Exactly right! I am agree with you.
9 month and waiting...
and waiting...
For complete %100 working accus, You need eeprom, mcu counter resetter debugger software and hardware.. Compatible with your accu mcu!!! Second if smd fuse damaged you have to changed.( mostly 35-50V /5~8 Amp), damaged mosfets, or opamps..sometimes mcu too..Thats most common problems.

Bro, my videos slowly gets views counts. I was assuming that till 25 December, it may become viral...
That's why... Anyway good question.
Thanks.
And watching it in Christmas, made me think why is? I thought that maybe TH-cam has replaced this music somehow
I did the same but notification says your battery is permanently failed.
Very good and clear video, thanks sir !
Excellent video! Thank you
Fun fact: Your multimeter is exactly the same as mine!
Company &model name
It's not good for long term use. The li-ion battery set need balanced charging. It's better to replace all the 6 cells.
Many Laptop batteries have a custom IC that monitors the cells and will permanently deactivate if new cells are installed. I assume there is some way to reset the IC for new cells, but good luck figuring that out.
How to reset ic

it's not for rich persons :)
Bravo merci beaucoup pour vos conseils !
Life saver. I want to refurbish a battery that is no longer in production so this is my only option.
Good video but... Why jingle bells?? XD
I don't recommend replacing few cells with totally different brand . As different cells made by different manufacturers react differently when plugged to recharge . You will overheat or potentially blast
No. Because the charge is balanced.
Hi, I hope you're still reading comments. Your video is most helpful I've seen. I have an old HP battery. Like your video, 1 set shows no voltage, but the other 2 are showing close to 4V. However, this battery has been sitting empty on my shelf for 3 years. Are the batteries really ok to use? And safe to recharge?
Thanks!
Good informative video, thank you.Saving lot of unnecessary spending purchasing new battery.
You can't do normal soldering on this type of 18650 battery. If you do so, the the extreme heat during soldering will destroy the battery life. That's why preferred method is spot welding.
Arjun Chatterjee exactly but don’t expect a person with a English accent like this one to care about things like that 😂
checking voltage with no load doesn't give a good image of the batteries real condition
With no load means? What load you want
The meter he's using was the load, wasn't it?
Well try a load of at least 1amp and see if the battery can handle it. How fast depleted?
Some people know nothing about battery and still trying to say they are expert 🤣🤣🤣🤣
@@mr.electronicsdevicevlog9333 True enough! The capacity of the battery is just as important - unless you just want a quick temporary fix!
@@dragonballthings688 When I was a young lad, my dad would drive his car to the garage for a battery test. I was fascinated to watch the mechanic put a heavy gauge prong with a big gauge resistor across its cells, with a meter. It sparked spectacularly, then the mechanic would take the reading. The same principle works on lithium batteries (without the fireworks), but scaled down. Modern meters take hardly any current compared to the old swing-needle analogue ones, unless they are designed to test batteries.

Repairing a battery while listening to the Christmas song made my day
And when the battery pack has reached such a low voltage that the internal charging circuit has switched off, how do you reactivate the charging circuit as it does not happen automatically once the battery pack has been "reconditioned" by the replacement of the faulty cells ??
Yes i needed the answer to this question.. someone expert please respond
Apply a voltage, until minimum required charge attained. Check power supply, for needed voltage. Or, charge each cell individually. I've done it with a tablet.
(I'm not an expert)
It's better not to solder the cells, as not everyone is professional. Better to give it to highly experienced person.
People are far more capable than you give them credit for. Professional is just a paywall for people who prey on others ignorance. Don't be part of the fear mongering culture that likes to keep people uninformed and incapable. For example: Did you know that barbers used to do dentistry? Imagine paying 20$ instead 4000$ for the same procedure.
Thank you for sharing ... I repaired my laptop battery.
you the great one in u tube very nice i like this video is have battery problem I ll do this thank you god bless you
this guy reminds me of my school English 😂
Ohhh.. Sorry we forgot that u are in the root of Sheksphere
@@libinthomas1841 yup! you got it right 😜
The white light indicates that the battery is 100% charged. But when u switch ON the laptop, it's only 73% charged. Why so?
DAD OF ADS good point, since it was old battery and I was not having new li ion cells, which I have re installed.
I have hp dv4 laptop. In my case, the white led beside the dc jack indicates that you have dc power and not to indicate 100% charged. There is another set of white leds located below the keyboard for hardisk activities, and charging condition.
I think it was a calibration issue, when the laptop battery was not good, it had let's say 85% of theoretical capacity in power available, so computer remap 85% of power to be 100% full. But when he turned the laptop on current was able to go into the battery so the computer understood it os not full, and will calibrate it again
