Step 1
Make the Survival Multitool first
Bring a Survival Multitool to harvest Acidic Raion Pouches, then collect two Copper for each battery you plan to make.
Starter power part
Basic Battery Guide
Basic Battery is the starter power part that turns scattered resources into real progression. It connects Acidic Raion Pouch, Copper, Scanner access, the Welcome Center power slot, and Habitat Builder preparation.
First battery: craft it at the Lifepod Fabricator from 2 Copper and 1 Acidic Raion Pouch. Reserve a battery for the Scanner and another for the Welcome Center power slot before making extras.

Why the first battery matters
The first Basic Battery is not just a power item. It is a route unlock: it lets the Scanner path, Welcome Center step, and Habitat Builder preparation start to connect. Treating it as a disposable spare is the common mistake.
If you are playing co-op, agree who is spending the first battery before everyone starts crafting. One battery in the right place can move the whole save forward; two spare batteries in separate backpacks can leave the group with no clear progression step.
Crafting route
Step 2
Search the Lifepod cave loop
Start with the shallow caves around the Lifepod and nearby starter routes. This keeps oxygen risk low while you gather Copper and Acidic Raion Pouch leads.
Step 3
Craft at the Fabricator
Craft 1 Basic Battery with 2 Copper and 1 Acidic Raion Pouch at the Fabricator.
Step 4
Spend the first battery deliberately
Your first Basic Battery usually unlocks more value as Scanner or Welcome Center progress than as a spare part sitting in storage.
Starter route anchors
Start with the cave below the Lifepod or the nearby east cave. Harvest pouches with the Multitool, check covered rocks for Copper and return with air in reserve.
Pouch lead
Acidic Raion Lifepod cave
Check the cave directly beneath the Lifepod before swimming farther out.
Backup lead
Acidic Raion east cave
PC Gamer describes another lower cave level roughly 30 m east of the Lifepod.
Power use
Welcome Center approach
Swim south-southeast from the Lifepod; bring a Basic Battery before making it a full stop.
What to use it on first
| Use | Priority | Why it matters |
|---|---|---|
| Scanner route | High priority | The Scanner unlocks fragment and lifeform progression, so Basic Battery is part of the first serious information loop. |
| Welcome Center power slot | High priority | Bring one Basic Battery to power the Welcome Center terminal. |
| Flashlight and safety tools | Useful backup | Carry spare power only after the Scanner and route-critical tasks are covered. |
| Habitat Builder preparation | Planning link | Habitat Builder needs 2 Titanium, 1 Glass, 1 Basic Battery and 1 Copper Wire. |
| Spare batteries | Later convenience | Do not overcraft batteries before you know which early tools and stations are actually blocking you. |

Basic Battery FAQ
How do I craft a Basic Battery in Subnautica 2?
Use 2 Copper and 1 Acidic Raion Pouch at the Lifepod Fabricator to make 1 Basic Battery.
Where do I get Acidic Raion Pouch for a Basic Battery?
Start in the shallow Lifepod cave loop and nearby starter caves, then harvest with the Survival Multitool. Keep the cave entrance in view and return with enough air to reach the Lifepod.
Should my first Basic Battery go into the Scanner or the Welcome Center?
If you do not have the Scanner yet, craft it first. If the Scanner route is stable, carry a Basic Battery to the Welcome Center so you can power the facility and continue biomod and Habitat Builder progress.
Is the Welcome Center powered by a Basic Battery or a Power Cell?
Use a Basic Battery in the Welcome Center power slot. Reserve Power Cells for compatible vehicles and larger equipment.
