Batteries

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, and whenever there isn't enough energy being produced, batteries are automatically drained.

Batteries individually have their own input and output speed limits depending on their size; Small Batteries can absorb or release power at 1U/s, which for reference is approximately one bar on a Small Battery every four seconds. Medium Batteries behave like three Small Batteries, at 3U/s, and store and release energy three times as quickly.

Small Batteries
After completing the necessary research, you can craft a small battery in your backpack's printer using 1 Lithium.

You can plug it into any slot on your backpack or base, including the backpack's widget slots. It stores up to 32 Units.

When placed in the backpack, it increases the total energy storage available for Terrain Tool augments by 320%.

Medium Batteries
You can craft a larger battery in the Small Printer for one Lithium and one Zinc after completing the necessary research. As it is a medium-tier module, you can place it in any medium-tier slot.

It stores up to 256 Units.

Packaging and unpacking Medium Batteries does not retain any data on the original battery like power.

Backpack Power Notes

 * Rovers, Backpacks, and Batteries have different actual power densities, and the backpack in particular has 25% the storage capacity per-bar compared to Small and Medium Batteries.
 * Consequently, a Small Battery plugged into a nearby Rover or Large Platform can fill the Backpack's battery more than three times before emptying, and when plugged directly into the backpack can extend the time for using Augments by more than 300%
