Can anyone tell me how to check Laptop battery health ?

The shop I purchase this laptop he said he can replace the battery with other x1 carbon battery. Which have battery health 82% but if I do battery guage reset that battery I am assuming it will go more lower than 75% and I am not sure about how many cycles it ran. So, I am thinking to keep my laptop with this battery. What do you suggest ?

I'd say your current capacity should be fine for now.

Usually, you would only need to replace your battery when the capacity gets real low (ex: 30%), or if you notice any swelling of the battery. Always immediately replace a battery if it's swelling any at all.

I don't think that they have a model for laptops to replace the battery yet, but in your desktop you could simply add the QBX-1 nuclear reactor card to provide an alternative source of power:

I've seen sudden drops in my own batteries of up to 8%.
In addition, I have never seen any estimation of accuracy for any battery measurements. When I was investigating power use during S3 Sleep, I discovered that the %-charged icon in the Taskbar SysTray ["Notification area"] can have inaccuracies of 3% so it might be that all battery-related measurements are similarly inaccurate for all any of us know.

I agree with you. There's no persuasive argument for changing it.

All the best,

Agreed.

Roger that!

Batteries are strange animals. I have an HP laptop that is 10 years old, still has the original battery and that battery is working fine. I have another HP laptop where after 2 years ALL the cells started to swell. The symptom was that the buttons on my touchpad became hard to press. I thought it was a bad touchpad. Then the touchpad started to bow up out of the computer case. That's when I realized I had a battery issue where the swollen cells were putting pressure on the touchpad.

HP was kind enough to replace the battery free of charge even though I was not under warranty and the replacement has been working for about 2 years now.

I would say it depends on your use cases. If you do cross-country flights and you use your laptop most of the time, that's a different use case than if you use your laptop for one hour at the local coffee shop.

For me, since that first case was true for me, I even carried extra batteries back when total battery life was more limited than it is now.

True, but unfortunately most newer laptops do not have easily removable batteries to swap with fully charged batteries as needed.

Sad, but true. I've replaced several "flat pack" batteries (including some swollen ones) and they all required at least partial disassembly of the computer. The worst one was a Lenovo Yogabook which required removing the glued-on keyboard using a blow-dryer and a suction cup to get access to the battery. What were the designers smoking when they came up with that design???

Agreed. It seems they make them way too disposable now, but without the cheap disposable price.

I have changed the battery because yesterday it dropped from 27% to 6% directly. So, I told to the seller guy he said come to the shop and he will replace it. But the point is on Windows 1 the battery number and battery health is same as before ?
