How to craft a basic battery in Subnautica 2

Subnautica 2 players can craft a basic battery early on using copper and an Acidic Raion Pouch.

The battery is made at a replicator once the required materials are gathered.

It powers survival tools and helps restore a small outpost, making it key to early progress.

Because it supports exploration and survival, the battery is an essential early-game item.
