Why do batteries have a plus and - sign?

Because one side is the positive side (+) and one side is the negative side (-) They need to be there so people can place them in correctly. On objects there is also a plus and minus sign to match with the ones on the battery. You place the end with the plus sign in to match the end with the plus sign on the object and the end with the minus sign to match the minus sign on the object. Hope this helps!
