LOW FPS DELL INSPIRON 7559 W/O BATTERY

Hi, i have an Inspiron 15 7559. Last week my battery  was damaged and can't use it anymore, since then I have low fps while gaming (gta v, witcher 3, etc.), I've read there is a kind of throttling when there is no battery, maybe the turbo boost is not being enabled.

Is there a way I can make the laptop work again like before, I can't buy a new battery yet because I live in Peru and is hard to find this battery model.
