Is it possible to replace the banks in the laptop battery with something more capacious and / or durable? Let's say not lithium-ion, but lead perhaps?

Question

Batteries

And then I have a weak battery in my laptop decided to replace the banks.
So I thought about whether it is possible to replace lithium ion with something cooler, but at the same time without the need to solder the motherboard for new banks.
I'm probably asking a stupid question, but maybe...

Answer 1

Yes, you're just asking nonsense.
Find out the mass-dimensional characteristics of lead first.
And cooler just lithium. Although it varies.

Answer 2

you have already been told about lead - so let's skip this nonsense.
take normal banks from China, read the reports on the flashlight. they will not be cheap, but the best option in terms of power.
Consider this option, many batteries have controllers with a limit on the number of charges. And you can’t put the left battery in such a laptop, so you will enrich the manufacturer.
option 2: look for an enlarged battery for your laptop. it will stick out of the body, but there will be more power.

Answer 3

Nothing prevents you from powering the laptop with the required 19 volts (however, 18 is enough there) not from a network power supply, but from one and a half car batteries, with a capacity of at least 40, at least 100, at least 250 ampere-hours. Just like that, take one whole, the other with a tap from three cans (for many batteries, lead jumpers are available for connecting a tap), and connect in series.
But all the care about recharging such a homemade product (and other maintenance - checking the electrolyte level, topping up with distilled water, etc.) will lie with you.

Answer 4

The Chinese have DC-DC step-up converters 12 v --> 19 v for laptops, which allow you to power it from a car battery.
