Windows shows 100% battery power, but it turns off due to a critically low battery level?

Question

Windows

This happens when an adapter is connected, and when this happens without an adapter connected, it simply cuts off without saving data (without going into hibernation mode). The battery was recently replaced. What to do?

Answer 1

What to do?

Throw out the battery and put in a good one.
The battery charge is determined by voltage.
A new, serviceable battery takes a long time to charge and during charging, the voltage gradually increases.
A faulty battery will quickly reach its maximum voltage when charging. Any time you try to connect a load, the voltage drops immediately.

Answer 2

Kick the battery or its controller. Repaired either by resetting the controller or buying a new original battery
