If your laptop can't hold a charge like before, replacing the battery is a simple and affordable solution that you can do yourself. Nothing has a more direct impact on the life of the computer than the battery. You'll need to replace your laptop's battery when its runtime doesn't last as long as when you took it out of the box.
