Universal Scale Models 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

@Miniatures-And-More 4 года назад

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

Gostei muito do seu vídeo me tirou umas dúvidas o meu notebook só tem 2 celulas vou acrescentar mais para ficar com 4.

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?

@Miniatures-And-More 4 года назад

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

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.

@Miniatures-And-More 4 года назад

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

@rajeevkumarkarwayun5458 3 года назад

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

@Miniatures-And-More 3 года назад

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

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

@Miniatures-And-More 3 года назад

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.

@Miniatures-And-More 4 года назад

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

@yebokul5837 4 года назад

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?

@Miniatures-And-More 4 года назад

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

@yebokul5837 4 года назад

Well, the battery barley last for 30 minutes, and it's percentage will be 100% till shutdown.

@yebokul5837 4 года назад

What to do please?

@Miniatures-And-More 4 года назад

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

@geraxdeon 4 года назад

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 ?

@Miniatures-And-More 4 года назад

Please Check the connections thoroughly , And can you tell me the exact state of your laptop battery before repair ?

@geraxdeon 4 года назад

@@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. m.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-04sNLJ8Vdjk.html m.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-I7Llii69YYM.html

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!

@Miniatures-And-More 4 года назад

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 !

@carrickmchwain2296 4 года назад

@@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. :(

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
