Step 1
Make the Survival Multitool first
Public guide coverage ties Acidic Raion Pouch harvesting to the Survival Multitool. Do not swim out for battery parts before you can actually gather the pouch.
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 Copper and Acidic Raion Pouch according to public guide support, but use the current Fabricator text for exact counts. Spend the first one on Scanner or Welcome Center progress before making spares.

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
Use the current Fabricator text for exact counts. The supported ingredient pair is Copper plus Acidic Raion Pouch, but counts should remain current-build checks.
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
Use these as shallow route anchors for the battery chain. They are not final spawn tables; they keep the battery task connected to oxygen-safe starter travel.
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 | Public launch guides identify the Welcome Center interaction as a Basic Battery step, not a Power Cell step. |
| Flashlight and safety tools | Useful backup | Carry spare power only after the Scanner and route-critical tasks are covered. |
| Habitat Builder preparation | Planning link | Base-building guides connect Basic Battery to early Habitat Builder planning, but the exact crafting row should be checked in-game. |
| Spare batteries | Later convenience | Do not overcraft batteries before you know which early tools and stations are actually blocking you. |

How the links were chosen
Crafting association
Basic Battery sits between starter biological gathering, Copper routes, and the first meaningful tool chain.
Route association
Lifepod cave, Acidic Raion Pouch, Welcome Center, Scanner, and Habitat Builder searches belong to one first-hour path.
Player-risk association
The common mistake is swimming to the Welcome Center without a battery or spending the first battery before scanning unlocks.
SEO association
Basic Battery, battery recipe, Acidic Raion Pouch, Copper, Scanner, Welcome Center power, and Habitat Builder are one intent cluster.

Basic Battery FAQ
How do I craft a Basic Battery in Subnautica 2?
Use the Lifepod Fabricator and check the current recipe row. Public guides support Copper plus Acidic Raion Pouch as the ingredient pair, but exact counts should be verified in your build.
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. Use route markers as leads, not fixed spawn tables.
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?
Public launch guides identify the interaction as a Basic Battery step. Bringing a Power Cell is a material detour unless your current build shows different text.
