Other forms: batches; batching; batched
A batch is a completed group, collection, or quantity of something, especially something that's just been made. You might, for example, bake a batch of cookies to take to your new neighbor.
A company that makes soap might deliver a batch, loaded on a truck, to a new store in Vermont, and if you manage a bakery you might declare, "That's it! This is our last batch of gingerbread until next year!" In computer lingo, a batch is, similarly, a group or collection of records. The Old English root, bæcce, means "something baked," from bacan, "bake."
