Can anyone tell me how to check Laptop battery health ?

Hey,

I want to know how to check Laptop battery usage time as I see there is usage history and battery life estimates. Moreover, I want to know if my Laptop battery health is in good condition ?

Battery Health was 88% and after doing battery Guage reset its now 78.4%.

I don't know if this Battery information will interest you. It contains a LOT of useful information [ taken from one of my Scripts ] that you might find useful.

Copy & Paste the following into a CMD Prompt and press Enter . . .

I hope this helps.

Whilst there is no formal definition of battery health, the generally-accepted meaning is the ratio of
Full charge capacity / Design capacity.

In your case that is 78%.
So you have only used up 22% of its potential lifespan.

Hello,

In addition, you could generate a battery usage report below to help learn more about the health of your battery.

Generate Battery Usage Report in Windows 10

The main thing is to look at your Battery capacity history from the report to see how much "full charge capacity" you currently have left compared to its original "design capacity".

From your report below, you have lost some capacity which is normal over time, but it's nothing to worried about. It's needs to get much lower before you need to think about replacing the battery.

It's normal for it to fluctuate some, but not sure why it dipped like that after doing the battery Guage reset. Hopefully, it will not dip anymore like that soon.

On battery guage reset why charge capacity lost I dont understand this till now.

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.

So, I am thinking to keep my laptop with this battery.

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