Quick answer
Current blueprint data lists Basic Battery as unlocked by default. Craft it at the Fabricator with Copper x2 and Acidic Raion Pouch x1. Subnautica2Hub lists it at 100 energy, and the battery feeds early tools plus the first Power Cell chain. Once Advanced Battery and Battery Terminal are online, stop treating Basic Batteries as throwaway items.
Field notes for early power
Make the first battery on purpose
The first battery is not a spare part. It is what turns Scanner, Repair Tool, and early build routes from errands into a plan.
Copper disappears faster than it looks
Two Copper per battery is not scary until Copper Wire and builder recipes start asking for the same pile. Keep a small raw Copper reserve beside the power locker.
Do not feed tool batteries into the vehicle chain
Power Cell needs Basic Batteries, but stealing from Scanner or Repair Tool creates a worse problem. Make fresh batteries for vehicle work when possible.
Basic Battery route
Craft one before the scan run
Scanner planning starts with battery planning. If the first battery is missing, every fragment route gets slower because you keep returning to base empty-handed.
Collect Copper in pairs
The current recipe is Copper x2 plus Acidic Raion Pouch x1. Pick Copper in pairs so you know when a battery is ready instead of guessing from a mixed locker.
Keep pouch runs short
Acidic Raion Pouch is the odd piece in the recipe. Grab it on a focused food-and-power loop, then go home before the trip turns into a random inventory sweep.
Do not overcraft batteries
Copper also feeds Copper Wire and several early electronics. Make the battery you need for the next tool, then leave enough Copper for Scanner, Habitat Builder, and wiring work.
Split tool power from vehicle power
Two Basic Batteries can become a Power Cell, but that is a different plan from keeping Scanner and Repair Tool alive. Keep a small note on the locker so vehicle crafting does not steal every charged tool battery.
Label the power locker
A small battery locker saves time once Flashlight, Scanner, Repair Tool, and base projects all start asking for power parts.

Basic Battery checklist
| Need | Why it matters |
|---|---|
| Fabricator | Basic Battery is a default unlock in current data. |
| Copper x2 | The part most likely to be stolen by Copper Wire. |
| Acidic Raion Pouch x1 | The organic ingredient that makes the recipe easy to forget. |
| 100 energy | Subnautica2Hub currently lists the output at 100 energy. |
| Tool queue | Scanner, Flashlight, Repair Tool, Habitat Builder, and more pull from battery planning. |
| Upgrade split | Power Cell uses Basic Batteries; Advanced Battery should move into the Battery Terminal rotation once unlocked. |
Batteries can quietly eat your whole Copper stack
A spare battery feels useful until you need Copper Wire for the next craft. Keep one working battery, maybe one backup, and save the rest of the Copper for the tool chain.
