Why is it that the laptop turns off easily when using it with a battery?

It's okay if I just connect to Adapta.

When using the battery except for the adapter, there is a phenomenon that the laptop turns off even though I checked that there is a lot of battery left.

And if you connect the adapter right away, the battery is 0%.

What's wrong with this?

It's because I used up my battery.
That's why I get discharged quickly.
Buy a new battery and change it.
