There are 3 types of batteries. You can check which compnents you need by looking at the Tinker Table. Then, in your inventory, search for these components and hover over them. Then press "R" and it will display the recipe. Once you have all components, go back to the tinker table and select the battery. Then click "Install" on the bottom of the Interface.

P.S. Capslock doesn't always help.
