Replacing Laptop Battery Cells

Hi, in this video i have shown how i have replaced my Dell Inspiron 1545 laptop battery pack cells with newer ones. the new cells are of higher capacity and provide a longer runtime to the laptop.
i have used my DIY Spot welder Kit to weld the 18650 cells together with nickel strips. you can check out that project here: • DIY 18650 Battery Spot...
Spot Welder: bit.ly/3vmHlTX (V8 Version)
after welding the cells together, i soldered the battery circuit to the cells, placed the cells inside the battery casing, and closed the casing tightly.
insert the battery into the laptop and charge the laptop for atleast 4 hours before using for the first time.
once completely charged, the laptop can now be used normally. the laptop now gives a better backup of about 3 hours compared to the 1.5-2 hours of the original battery, thus the project is a success

I wish I had this skill of that soldering those 6 batteries into a series battery! Very happy to see such a clean work. Thank you friend for showing a clean DIY.

[@thisismychannelleaveit]

Try it out! A couple practice runs, and you can do it for sure. Soldering like this is a bit trickier with things being smaller, but a good place to start learning is on copper plumbing pipe. It's a great skill to attain! 👊

Putting 10 high power welds on a cell in 5 seconds is gonna cook the insides, you know you can always just wait in between cells, I usually just tack them on then come back to each cell once I've let it cool down to minimize damage

[@kohatian35]

It will not work bu just replacing cells . .have to reset or unlock BMS

[@calvitocalvon1711]

Whats that?

[@OMARENGG22]

If he used non oem battery pack it won't need a reset

[@SingTodayi]

And how do you UNBLOCK the battery CHIP? It wont work like that.

[@passionatebeast24]

Use non branded battery for cheap. And replace cells. It will work.

[@elieelias6071]

Can you please tell us all the tools you used for this process

[@ryker86]

What if you have a battery with a micro-controller and it's still not recognizing the battery after replacing the cells?

[@jamesdemuro5923]

Does the bcb needs resetting ?

[@TechnicalSonu2001]

Sir mere pas hp 2560p ha oski battery k cells konsy lagy hogy or market me ktne k miljaygy

[@ehsanali90]

Does the software need to be on the battery? Please explain

[@D-Man_Jam]

the second i saw the inside, i was like 'nope' and ordered a new battery instead

[@nixxonnor]

Changing the cells is easy. The hard part is to make windows accept the battery after the cell exchange

[@iFound99]

Good Video ❤

[@aswfl7061]

good job

[@patomansvibration6521]

Please did you reset the BMS? I did the same thing I changed the battery cells, but I didn't get any voltage on the positive output terminal. Is there any solution please?

[@mdplays9638]

same here 😔

[@PNWLiving1725]

Does it matter how many spot welds you put on battery?

[@david.st1]

the more the better, but dont overdo it. you should get feeling when the connection is strong 🤔

[@danyalahmad2097]

Can we use higher capacity cell?

[@escapetherace1943]

yes you can as long as the voltage is around the same. The problem though is this doesn't work, and if it does your laptop will show ZERO or a random % number and will never tell you how much it's charged. You have to reset/reprogram the chip which acts as a controller inside of the battery, you can't just put new cells in.

Avec mes remerciements pour l’exercice

[@420gramas7]

As far i know there is a chip which counts charges and its not that simple to reset it

[@772777777777777]

I think your correct!!!

[@Sikhbuddy007]

all the DIY Battery people are fake, it does not work like that, the moment you take the battery board out of batteries it gets locked, even after replacing with new batteries it will not work.

[@rebaznajatmajeed]

@@Sikhbuddy007 right ... Mine is giving the right amount of voltage yet not working

[@ATULSingh-rs2sl]

Yes

[@daniyalahmed2154]

No you have to reprogram it to get it unlock

[@usmanafzal1625]

apki shop kahn ha

[@agostinhomatos321]

I checked with a spare laptop battery made in China, and like many other equipment made in China, they are nor done to be later maintained, there is no protuberant area to open the battery, everything is flat and soldered, you have to destroy it to open it. Better explain how to build a laptop battery from scratch.

[@cheezyfriez12]

It's probably best to do this outside, since there is a fire hazard.

[@philippm8039]

Wtf have you build your own spot welder? 😅

[@yus.e_f]

شكراً جزيلاً لقد استفدت كثيراً

[@maatiraouki5183]

💐🌺🌹👍✌️👏⭐️❤️

[@Accessgp]

Most importantly battery cases do not open so easily, hence find it hard to trust this video

[@juancarlosmonteverde6718]

use pure eaucalyptus oil to open charger and battery cases easily

[@Accessgp]

@@juancarlosmonteverde6718 Interesting any specific way to use it?

[@chongtak]

Haven't done it on batteries but have done it on adapters, just drop some petrol on the joint and the glue melts.

[@arif_ar]

are you mute ?

[@ghazwanalshghai3893]

good job
