Battery notebook always always 0%?

Today I found out my old notebook that I haven't used for a few months. Before everything was fine, now the battery suddenly stops working. The device no longer starts without the power plug, and the display in Windows 7 is always 0%. Where can that come from, can you fix it?

The battery is history

Batteries have a limited lifespan, buy a new one.

Alright, I was just hoping that there was something else you could do. ^^

What kind of device is it and what will or should it be used for?
