Astroneer Wiki

Hello all editors and users of the Astroneer Wiki! We are in the process of updating and switching over to use the new Fandom Desktop skin on the wiki. There will be many changes over the coming days, but the main goal is to keep the wiki feeling the same, as much as we can! If you notice any issues once the swap is made, please post them to the Admin Noticeboard so we can address it right away. We are also going to be completing the update to the Astroneer Wiki:Style guide, so there is a more up to date guide on how to style the wiki going forward.

The Medium Battery is a power storage item in Astroneer. It can hold more power than a Small Battery, and makes for a good reserve of power mid-game.


Output Input Module
Medium Battery Zinc
Small Printer


  • Power Throughput Rate: 5 U/s
  • Power Capacity: 512 U
  • The Medium Battery has 16 visible columns, each of which is equivalent to 32 Units.

Like the Small Battery, Medium Batteries accumulate power when production of energy exceeds demand for energy. The Medium Battery will give away its stored energy whenever the network doesn't produce enough energy.


  • Traveling to different planets will make the yellow bars move off of the center of the battery. The moved bars can not be collided with, but do move the outline of the battery when hovered over. Extensive space travel worsens the effect. This can normally be fixed by either resetting the game or packing the battery, then unpacking it.
  • Lacking visible horizontal lines to mark individual 'bars' found on the Small Battery, each of the 16 vertical columns is effectively eight bars on a Small Battery.
  • Accounting for size efficiency, it could ostensibly be useful in some situations to fill a Medium Storage or a Medium Storage Silo with Small Batteries if throughput is desired.


  • Medium Batteries used to be able to be found deep in caves at the end of tunnels rarely.
