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.

A Battery can be charged in the Battery Charger, or an equipped tool can be recharged with Swim Charge Fins. These devices allow the player to keep using their tools without having to continuously craft new Batteries.

Spoiler alert: The following section contains story related material.

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