Battery (Subnautica)

The fabricator has substituted standard battery acid for an acidic compound synthesized from local flora. ― PDA, Dialogue

Batteries are electronic items crafted using a Fabricator. Batteries are used to craft electronic tools and pieces of equipment, providing them with Energy. Batteries can hold up to 100 Energy, which is drained when using Battery-powered tools. Batteries can be swapped out or removed from tools by equipping the tool and pressing the "reload" button: this will bring up a display where the player can scroll through their other batteries to select one, or select the "X" to remove the battery and leave the tool without one.

Ryley cannot move while swapping batteries.

Batteries can be charged in a Battery Charger, or through an equipped tool with Swim Charge Fins. Chargers have to be installed in a powered seabase or Cyclops first, but the latter allows tools and batteries to be charged during use.

Ion Battery

The Ion Battery is a modified, higher capacity version of the Battery, which can hold up to 500 Energy.

Trivia

Depleted batteries can be used in crafting to create tools and power cells that are fully charged. This is an oversight by the developers.

As Repair Tools do not require, but comes with a fully charged battery upon fabrication, they can be used to cheaply produce batteries without copper or mushrooms.
