Before changing the battery, make sure your charger is ok. Take it to a shop and have it tested. Also laptop batteries usually are not universal, you would have to buy an original from the manufacturer, which can be expensive, if at all available. Sometimes you can find a cheaper imitation though, just google for it. These cheap batteries however may actually be worse than the one you have already.
