This is really helpful ty just a quick question if I connect Li on 41865 and liyang 18650 will that be ok? Or do I have to change all
check all the voltages of cells individually , If there is a drop in voltage of atleast 1 Volt ( ex.3.7 - 1 V = 2.7 V ) , Then you sure need to change that cell , Good Luck
Thanks❤️
Great video, might I ask - if I replace all cells (6) do every cell need to be the same voltage? If I buy new and not all cells are the same voltage 3.81V for example - Do I need to charge or discharge the cells so they will match voltage?
It is always better to see that the replaced cells are all of same voltages , But however this will not be possible if you buy cheap quality ones , I recommend Samsung or Panasonic , Initially once you have replaced all the cells (6) You must charge them for at-least 8 hrs , Good Luck
Thank you.
You're welcome!
It really Worked , Thanks a lot
Glad To Know That
THANKS FOR YOUR TUTORIAL ON LAPTOP BATTERY RECOVERY BUT HOW TO SELECT GOOD CELL FROM OLD LAPTOP BATTERY THAT!S VIDEO IS NEEDED FOR COMPLETE KNOWLEDGE, THANKS
Thank you for your comment , Usually You need to check the cell Voltages , Select the Maximum voltage battery, the required is 3.7 Volts , Anywhere above 3 V is good too . If you don't find a cell with this voltage then use new ones , Good Luck.
When you solder wires, it could be fixed back to battery case. They need spot fixing with a device. I tried to repair but failed as i could not solder nickel strip. Thanks
Hello Rajeev yes the strips are attached by spot welding to the batteries , you can solder them as well , to do this you need to tin the plates and battery terminals , Apply a thin coat of flux and use atleast 50 watt solder iron you can do this in this method , Good Luck
@@Miniatures-And-More thanks will give it a try.
Hi Its really hepful and simple information easy to understandd.Could you please help for my Sony Vaio VGN CR 35G model laptop battery replace? Where can i get its battery and could you replace them please, if i send the cell to you? I am from Hyderabad , India.
Thank you for your feedback , I am sending the link where you can buy the cells and replace them by yourself as shown in the video bit.ly/3gUHXYB , good Luck
Great Job !
Thank You !
Nice method, keep helping
Thank you for your comment
Can we connect battery with wire instead of metal strip ,?
Sure You can , But see that the wire is compact enough
Mujhe help yeh chiye ki
Laptop ki battery me mine 2 cell dead paya usi kitte mAH. ki battery se replace kru usme kahi value nhi likha hi
Aur kya soldering krte time ya charging krne se ye fat sakta hi kya??
Hello Use 18650 Cell Nominal Voltage: 3.6V
Nominal Capacity: 2,850 mAh , Be careful while charging using other methods , Just check if you are using proper voltage and current , See if the Battery is not over heating while charging , If yes then chances are it will burst. Good Luck and Take Care
@@Miniatures-And-More THANK YOU so much
Já ganhou mais um escrito
Nice
Thank You !
Bro, I have rebuilt my Lenovo Laptop battery with 4 new cells but Error shows "0% plugged in not charging", please help me what problem?
Old cell: 3.7v/2200 mAh, Sanyo
New cell: 3.7v/2500 mAH, Samsung
Does the cell have protection circuit?
Yes Cell do have protection system , They are designed to not exceed certain temperature else they explode
@@Miniatures-And-More Thank you very much for the reply.
Tested voltages of individual cells in my battery pack, they're about 3.9 volt, now confused as to which to replace.
The battery wear level is about 99% already critical.
What do i do please?
What is the percentage decrease in the backup time of the battery ?
It seems the cells are woren out to max limit , I suggest use new cells for this battery pack
Well, the battery barley last for 30 minutes, and it's percentage will be 100% till shutdown.
What to do please?
Where are you from?
so that i can send you the shopping link to buy the cells , There is only one way , You need to replace the new cells , I am sure there is no other problem with the Circuit board
I'm from Nigeria
nice
Thank you ! Cheers !
well the hardest of repairing a laptop battery is opening it
Hm Not Actually Just Don't be Lazy : )
I did the exact same thing but it didn't work. Actually I replaced all (6) cells. When put the battery on my laptop, windows says 80%. But it's always 80%. Nothing changes and if I unplug AC adapter, laptop shutdowns immidiately. What can I do? Any advices ?
Please Check the connections thoroughly , And can you tell me the exact state of your laptop battery before repair ?
@@Miniatures-And-More Thanks for answer. Battery was healty. I has drained approximately 9 Amps and 3.4 V each cell. Total battery voltage was 10.2 V. I search on the internet and I found whats the problem. I cut the BMS POWER CABLES. If you do that the BMS board inside the battery cuts the power and gives no output. Something like protection mode. But it even worse. There is a trick to get back the battery to life but it may not be work. I will try this trick today. NEVER CUT THE BMS CABLES. And watch this videos.

@@geraxdeon Thanks. The links were helpful
@@geraxdeon Hey! How do you do for replacing your cells if you don't cut the cables?
@@barbeapapa7263 I cut BMS cables so my battery died. But you must first add parallel the new cells to BMS. Then cut old cells and cables from BMS.
I am not able to solder on metal strips
Hi , Firstly Clean the metal parts with fine emery 800 Grit or using a scotch brite , You must use High Wattage Solder Iron for this , use appropriate flux and tin the surface first , good Luck
Hi, I'm hoping you are still reading your comments. It is hard to get updated information on lithiums these days. I have a couple of questions I hope you can help me with.
1) I have an old HP laptop battery. It was completely drained when I left it on the shelf for 3 years. I used it previously for 4, so it is 7 years. I checked the voltage it is 6 cell 18650, 2 each. So 1 parallel cell is dead, but the other 2 are showing around 4V. Can these cells be recharged?
2) My current battery voltage is 4.18V, 4.06V, and 4.03V. Why is the 1st set so high? I was under the impression that lithium batteries lose voltage as they age, not gain? This battery currently only gives me 55% b/c it laptop won't charge if the voltage is above 12.55.
Thanks!
Hi McHwain , Yes I do read my comments regularly , Battery technology has been a need of the hour these days , There are plenty of research on batteries , Since this is the final option of energy source for humans as per my belief,
To let you know, I had a wrist watch which i purchased about 12 years ago and can you believe it , It is still working fine no issues until date :) ,
It usually is designed to last longer but there are certain conditions which has to be met to get the most of it , We usually either Over Charge a battery or Under charge ( Deep Discharge ) a battery , this is the main cause for a battery to fail slowly and continuously .
So in your case too i can only tell it for sure the cells can actually last long depending on the design ( I mean each company produces it in a different design ) not all cells are same and alike , If that was the case then there would be no more than one company producing them .
So my line is even each cell is slightly different in its composition , It is not exactly 100 % identical , Since this is how mass production in factories work . The little changes can change everything. ( tolerance +/- )
Finally your laptop battery is not able to hold more charge it its cells ( End of Life ) this is evident in the voltages its is displaying , So make sure all the cells in the battery are of same voltage ( Nearest ) and try it, Am sure you can get better result and your problem would be solved
Cheers !
@@Miniatures-And-More - Thank you for your prompt reply. I guess I have to replace the battery b/c that 1 parallel cell voltage is higher than the other 2. :(
@@carrickmchwain2296 My pleasure , but Sadly Yes , You need to replace the cells , Good Luck
my board is broken can i buy this
Hello , Yes some models are available , Let me know the Model and Specifications
Didnt work for me
Watch the Video fully , and follow the steps correctly its simple , Good Luck
I changed all cells but in output no voltage 😥
Please Check Voltages of all cells and Also Cross Check the Polarity , Good Luck
Mera sath bhi yahi problem ho gya h
