Find the clip on the back of the laptop. It should look like the image above:
Slide the clip to the unlock position
The battery should just slide of the back of the laptop
You need to find out what model and brand of laptop you have
when you know what model and brand of laptop you have you should go to the brand's websites and order the right battery for your model and order it
