Disassembly of Failed Laptop Battery - Ec-Projects

In this video I take apart a failed laptop battery to try and locate the cause of failure.

*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

Some of the protection boards set a register on an eprom and permanently disable the pack under thermal over heating conditions.

THANK, Thank you, for this recording!

[@mohammadaminakhavanrad674]

Hello Brother. Today I met your channel. With a quick look at the videos you made, of course, I only looked at the type of things you did to see your videos later. You got a big like for the hard work you have done and continue to do. I have good wishes for you. Always be healthy and happy and successful. Yours sincerely

Very Usefull video to learn new

[@soypopi]

Hello, could you please inform the connection scheme and battery polarity of this sony notebook? grateful and congratulations on the video!

[@s-nickos]

Could you give the part number of the controller's chip? By the way very informative video! Thanks!

A wide chisel works best for prying them apart by twisting action ;)

[@anirudhkundu3567]

Charge all the batteries individually by some other means. And then connect them the way they were connected to the BMS board. There are 2 ways to enable the battery circuit. 1. Connect the 12volt battery terminal to the actual +ve port on the laptop battery connector. It should enable the circuit. If not try the next step. 2. Keeping the negative probe of the multimeter on the battery pack negative terminal. Check all the pins for some kind of voltage which should be within 1.5 to 5 volts. If found any. Just ground that pin and the battery pack should start powering up.

[@Ramdileo_sys]

which are the 2 ways of enable the battery circuit.??

[@seeindarkness]

The circuitry of the battery should be pretty simple a microcontroller to handle charging and protection some fuses, mosfets and a voltage regulator for the micro. except for checking for voltages and mosfets, what else can you do ?

[@shubhammoonat7868]

Is it important to replace batteries with same MAH batteries???

[@darkoterzic4709]

Can you do dissamble of AS10D51 Battery from Packard abaell?I had desodered contacts to replace batteries but now i dont remember in what order should soder it again?Sorry for my bad English.

[@sammy2888]

I have the same kind of battery but not charging when fixed in the lap top ,took out all the batteries from the power pack and tested it . all cell shows 3.4volts as you did , what could be the problem ,,,is it the circuit problem or the battery problem

[@engsargen6674]

Nice dude

[@zoltankecse991]

Accu type is 18650?

[@costingabriel4628]

hi, it helped a lot i have A32-K53 battery model ..this was excellent, thanks.

[@EcProjects]

+Costin Gabriel You're welcome.. Thanks!

[@sammy2888]

Hi if it is the circut problem what board to change 2S or, 3S protection board ,,pse help n tks

[@hamideddaifi5615]

very interesting

[@rpm750]

Mads put the batteries from the failed pack into the original pack and see if that will revive the original pack. Or put the original pack controller board into the failed pack. Nothing lasts forever.

[@jemuzu0944]

I have the same battery cover its soo hard to open..

[@ronaldkimulasa7101]

Please help me out on how to reassemble it i am not sure how the circute is

[@ronaldkimulasa7101]

As10d51 battery

So, a battery indeed has a controller which disconnects it from Power Source to prevent over-charging. What's the harm in leaving the computer connected with power supply for a longtime even after the battery is completely charged ?

[@TheAmmoniacal]

There is no harm in leaving your computer connected to the charger for a long time, it all comes down to the life expectancy of your battery. According to "experts" the optimal long-term storing charge for a lithium battery is about 70%, this will give your battery the longest life span. This optimum life span will decline somewhat at both higher and lower charge levels, leaving your charger in the laptop will maintain a 90-100% charge. But unplugging and plugging in your charger to stay at 70% is really not a practical option, and the manufacturer of the laptop don't want you to run off with just 70% charge. So just leave it in :)

same with me

[@chrisnew7092]

I can't believe that each of those battery has 3.8v i bought 40 laptop battery on ebay

[@numbr6]

Successful open, failed repair.10,000 more, and you have a DIY Power Wall, I guess.

[@IBSGKSTUDY]

My Acer laptop 4820T bms battery connection with diagram pdf

[@growasetofballs2363]

it has to do with the 2 battery next to the 3, because its the 1 with the 5 and then the 3 with the 4, but not the 1 with the 2, and that mean that the 6 is left hanging, from my expertise I can tell you, because I studied there, and am old and know that that number combination is bad in nature, so it went against nature, and it then went bad, and so just connect it right, from 1 to 6

[@johannfr]

Nice. What's the name of that song?

[@EcProjects]

Parasail, it's in the KZbin library :)

[@johannfr]

EcProjects ahh, right! That's probably the reason I've heard it like a million times..! ;-)

[@satrsskills]

brother i also have this battery and i am not understanding series and parallel connections please make a video

[@Cheesabacha]

How to repair controller please sir guide..

[@huseyinsky7759]

Bro 18650 or 16650 ? Please

[@zlata-massajist]

18650

[@Leonardo47565]

My acer notebook, which is nearly 6 years old, has a battery model AL14A32 and it has failed, after the high temperatures due to climate change; the weather here got so hot that the battery simply stopped working

[@jemuzu0944]

Sooo hard to open

[@s.Andyyy]

I want diagram of this battery 🔋

[@zaprodk]

Maybe you should change the title - the title implies that "you" failed taking the battery pack apart, like something went wrong (caught fire when opening case etc.) Did you check the chemical fuse ? It's probably the MCU that blew the fuse intentionally to protect the cells from overcharge.

[@JustinCrediblename]

***** I didn't get that impression. I felt that the title described the video just fine.

[@tahayt6142]

Ye that's the one I has but I destroyed it

[@kosairox]

Like your vids but dude, clip your nails :D

[@TheAmmoniacal]

The nails are any engineer's best tool!

[@fahmidanial8664]

Its look like vape batteries

[@TwskiTV]

yes, it's the same kind of battery used in vapers, also the same kind of battery used in Tesla cars.

[@ritchiecassidy9151]

Boriiing

[@SabrinaVideo]

Change the title of the video and be more precise. You are making wasting people time for a not repaired video. Thanks. Meanwhile, I disliked the video.

[@EcProjects]

??? The title says disassembly, not repair. Not sure what you are talking about. Thanks for the dislike :)

[@s-nickos]

Could you give the part number of the controller's chip? By the way very informative video! Thanks!
