Windows warns you when your battery charge reaches low, reserve, and critical levels. You can, however, change the low, reserve, and critical battery level notifications in Windows 11/10/8/7, through the Control Panel.
When the charge gets low, the battery icon in the notification area indicates a low-battery level. The default value is 10%.
When your battery charge reaches the reserve level, Windows notifies you that you’re running on reserve power. The default value is 7%. At that point, you need to save your work and then find an alternate power source or stop using the computer.
When your battery is almost out of power, the battery icon indicates a critical-battery level, and then your laptop goes into hibernation. The default value is 5%.
If you don’t have enough time to act after seeing the low, you can increase the percentage of battery remaining for these settings. This can be especially useful for older batteries, which might not have as much storage capacity.

How can I be notified when my computer battery is fully charged?
Windows don’t offer any option in Battery notification that can send full charge notifications. You can either use a third-party app that can send a notification or keep the battery icon on the system tray and keep a check when it goes full.
Is it okay to use a laptop while charging?
Yes, it’s perfectly fine. Laptops are designed for such scenarios; if you cannot use them while on a charge, there is no point. The charging speed or time to get to 100% charge might slow down as you use the laptop. If you use any heavy application, the charging time will increase further.
