[quote=lalalalalalala]If the battery is really the cause of this, where can I buy a good battery[/quote] Any computer store should have the battery but make sure you know the make and model of ur motherboard in ur computer. Some stores can find the correct battery by using the make and model of ur computer if its a "name brand" like sony, hp or dell i have no idea of cost where you live here they are around $20USD.
