They only use them when there is no resource.

They should primarily use those batteries specially crafted for them, but yet they still power-up from my network.

Its better the way it is, otherwise the droids would plow though the batteries and still be draining your electric grid before you could research how to make them assuming you don't start with that knowledge.

Still its easier to factor in a few more generators than sort out the crafting to the point of making the droid batteries at least i would think in the start of the game.

Though maybe implementing some way of controlling which batteries they pull charge from would be a good idea i'm almost certain that its already in there but if its not then maybe this would be a way around the droids sucking your main grid dry when you need turrets not haulers.
