Quick answer
GAMES.GG places Battery Terminal fragments inside the Old Habitat area, roughly 380 meters north of the Lifepod, and says you scan two fragments to unlock the blueprint. Current blueprint pages list the build as a Habitat Builder deployable using Titanium x2, Quartz x2, and Copper Wire x1. GAMES.GG says the terminal can charge up to six Basic or Advanced Batteries at once. Use it for tool batteries; Power Cells and vehicle charging are a separate plan.
Field notes for battery rotation
Build it before the locker gets messy
Battery Terminal pays off before you think it will. Once tools, vehicles, and advanced batteries share the base, loose cells become hard to read.
Put it beside the power locker
A charger across the base becomes decorative. Put it where drained batteries naturally land after a trip.
Separate dead, charging, and ready
Three tiny piles beat one confusing pile. The whole station is there to stop you from crafting batteries you could have recharged.
Battery Terminal route
Bring a Scanner and enough oxygen
Treat this as a proper wreck-side scan run, not a casual pickup. If your Air Tank is still basic, pack food, mark the exit, and turn back before the last breath becomes the plan.
Sweep Old Habitat walls and compartments
GAMES.GG points players toward Old Habitat for Battery Terminal fragments. Move slowly around interior walls, side rooms, and exterior debris instead of swimming straight through the main doorway.
Scan two fragments before leaving
The guide data currently points to a two-fragment unlock. If you only have one, make another pass before going home so the trip turns into a build, not a note to return later.
Build the power chain first
Battery Terminal is useful only inside a powered base. Put Habitat Builder, Titanium, Quartz, Copper Wire, and reliable solar or generator power ahead of the terminal itself.
Use it as a rotation shelf
Keep one working battery in each tool and rotate drained batteries through the terminal. Do not craft new Basic Batteries every time the Scanner or Repair Tool gets tired.
Keep vehicle cells out of the charger plan
Battery Terminal is for Basic and Advanced Batteries. If you are building Power Cells for the Tadpole or later power projects, keep those ingredients in a different box so the charger habit does not blur the count.

Battery Terminal checklist
| Need | Why it matters |
|---|---|
| Scanner | Required to unlock the fragments around Old Habitat. |
| Two fragments | Current guide data points to a two-fragment unlock. |
| Habitat Builder | The terminal is placed as a base deployable. |
| Titanium x2 | The cheap base-building material in the recipe. |
| Quartz x2 | Easy to forget if you only planned electronics parts. |
| Copper Wire x1 | The processed ingredient that competes with base electronics. |
| Powered base | A charger without power is just a wall decoration with ambition. |
| Separate cell box | Keep Power Cell materials apart from tool batteries. |
Do not build it before the base can feed it
Battery Terminal solves battery waste, but it adds another steady power draw. If your first base already flickers at night, fix generation before filling the charger with empty cells.
FAQ
Where do you find Battery Terminal fragments in Subnautica 2?
GAMES.GG currently points players to fragments around the Old Habitat area, north of the first Life Pod route. Search wall panels, compartments, and surrounding debris carefully.
How many Battery Terminal fragments do you need?
Current guide data says Battery Terminal needs two scanned fragments to unlock.
What does Battery Terminal cost to build?
Current blueprint pages list the terminal as a Habitat Builder deployable using Titanium x2, Quartz x2, and Copper Wire x1. Check your in-game blueprint after each Early Access patch.
Is Battery Terminal worth building early?
Yes, once you have a powered base. It saves Copper by letting you recharge used tool batteries instead of crafting new Basic Batteries too often. Just keep Power Cell crafting in a separate storage box.
