How to make a laptop battery

Question

Batteries

So in the process I have a project to revive an old laptop.
Now I'm making a body on a 3D printer.
Question: is it possible to replace a standard battery (which I don't have: D) with a home-made powerbank, if so, how to implement it?

Answer 1

You can equip a laptop with a nuclear battery.
But seriously, you can do it. True, I don’t know how it is implemented in the laptop battery compartment. Each has his own. You need to study the specific scheme. But there is a shorter way - through the power connector. So and so it is possible. Then I just made power without a battery on an old laptop. And if based on a battery, then you need to use lithium-polymer batteries. You can get them in China. In Russia, probably, too, can be found. The rest, you need to look at the diagrams.

Answer 2

You need a power controller for batteries of just such a series of laptops. Further - according to the controller specification, hang standard 18650 cans in the required quantity and configuration.
If the controller is soldered on the motherboard, just look for a datasheet for it and see the typical circuit for connecting cans.

Answer 3

So in the process I have a project to revive an old laptop.

An indiscreet question - why?
Look at Avito or another flea market for the same or similar, but serviceable, with a case and a battery (the battery may be dead, but with a native controller) for 3 kopecks, replace the banks.
Place the PowerBank in the battery compartment, make it a 19V outlet (or do you have 12V power?) And a cord into the laptop's power socket. The same can be unsoldered inside, but PowerBank will become non-removable.
