How to Craft a Battery in Subnautica 2

To craft a Battery in Subnautica 2, you need 2x Copper and 1x Acidic Raion Pouch at a Fabricator. The catch is you can’t harvest the pouch bare-handed – you need a Survival Multitool first. Both resources sit in the cave directly below your Lifepod, so it’s a quick round trip once you know what you’re doing.

Recipe for Battery in Subnautica 2

The recipe for a Battery in Subnautica 2 is simple on paper but a little fiddly in practice. You craft it at the Fabricator on your Lifepod, and the blueprint is unlocked by default – no scanning required.

• 2x Copper: Common mineral deposit found on the seabed and cave walls near your starting area.
• 1x Acidic Raion Pouch: Harvested from the pink, brain-looking Acidic Raion plant. Requires the Survival Multitool to collect.

You’ll need a Battery for the Scanner, which is one of the first tools you should be building, and pretty much every other powered piece of gear down the line. Get comfortable with this recipe – you’ll be coming back to it a lot.

Craft a Survival Multitool First

Before you can grab a single Acidic Raion Pouch, you need the Survival Multitool. The plant won’t yield anything if you try to harvest it with your bare hands, so this is step one no matter what.

• Recipe: 3x Titanium, crafted at the Fabricator.
• Where to find Titanium: Scattered on the seabed right beneath your Lifepod. It’s the dark scrap metal lying around in the shallows – you can’t miss it.
• Blueprint: Unlocked from the start. No scanning needed.

Grab three Titanium, swim back up, craft the Multitool, and you’re ready to dive for an Acidic Raion Pouch.

Where to Find Acidic Raion Pouch in Subnautica 2

The Acidic Raion Pouch grows on a strange pink plant that looks like a brain with three bulging side pouches. The closest one to your Lifepod is in the cave directly below your starting position – just dive straight down and you’ll find the entrance.

Inside the cave, look for a glowing plant you can interact with to top up your oxygen. This is huge for newer players – you can stay down way longer without making a return trip to the surface. Use it whenever your O2 gets low.

When you find the Acidic Raion plant, aim carefully. Hit the side pouches, not the center bulb. The center is the Medical Gel Sack – useful later, but not what you need for a Battery. Right-click with your Survival Multitool to chop off a side pouch and collect the Acidic Raion Pouch.

Where to Find Copper for Your Battery

The good news is you don’t need to go anywhere else – the same cave that hosts the Acidic Raion Pouch is packed with Copper deposits. They stick out of the cave walls and are easy to spot once you’re inside. Hack them off with the Survival Multitool.

Grab way more than the two you need for one Battery. Copper feeds into a ton of early recipes, and you’ll burn through Batteries faster than you’d expect once your Scanner is in regular use.

Craft Your Battery at the Fabricator

Once you’ve got at least 2x Copper and 1x Acidic Raion Pouch, swim back up to your Lifepod and open the Fabricator. The Battery in Subnautica 2 sits in the resources menu, and the icons light up in colour once you have the required materials – so you’ll know instantly whether you’re ready.

If you’ve got the materials for two, craft two. One goes straight into your Scanner, and the second is a safety net for when the first runs low mid-exploration.

Tips for Crafting Your First Battery in Subnautica 2

1. Hit the Side Pouches, Not the Center

The Acidic Raion plant has three side pouches and one central bulb. The side bits are the Acidic Raion Pouch you want. The center is the Medical Gel Sack – save that for healing items later, but it won’t get you a Battery in Subnautica 2.

2. Use the Oxygen Plant in the Cave

There’s a glowing plant inside the cave that tops up your O2 when you interact with it. Use it instead of swimming back to the surface every minute. It’ll let you grab Copper and Acidic Raion Pouch in one trip without panicking about your oxygen bar.

3. Stock Up on Copper

The cave is full of Copper deposits, so don’t just grab the two you need. Copper goes into Batteries, Copper Wire, and a stack of other early-game recipes. Bring back as much as your inventory can hold.

4. Don’t Stress About Storage Early On

You can drop excess resources on the floor of your Lifepod without losing them. It’s not pretty, but it works as a free storage solution until you build a proper base with lockers. Save the box-crafting effort for later.
