Batteries are one of the types of Items in Astroneer which store power. When a surplus of energy is produced, it is used to fill a battery somewhere in the network (assuming all modules' internal batteries are full.) They can be filled or depleted at a maximum rate of 4 units/sec (or 1 bar/sec).
This page is about the external batteries; see the Power page for the differences between the internal and external batteries.
