Do brand new rechargeable batteries have a charge?

When a standard Duracell AA battery is manufactured, it contains all the charge it will ever have (right?), and can''t be recharged. But, for a rechargeable battery like a NiCd AA battery, or a lithium laptop battery, does the battery have voltage just from the process of putting all the materials together, or is it an "empty container" that then needs to be charged before

How Do Batteries Work? | OpenLearn

When a conducting wire is connected between the positive and negative terminals of a battery, one end of the wire becomes positively charged and the other end negatively charged. The difference in charge causes electrons to move through the wire towards the positive terminal of the battery, where they are removed from the wire.
