How to Swap Batteries in the Field
Every tool you craft comes with a fully charged battery pre-installed. When it runs dry, you do not need to craft a new tool. You can swap the battery out directly.
To swap a battery, equip the tool on your hotbar and press R on PC or Up (D-pad) on controller to open the reload menu. From here you can:
Replace: select a charged battery from your inventory to slot in.
Unload: remove the current battery without replacing it. It goes straight into your inventory.
| Tip! | If you run out of battery mid-dive, you can use the battery from another tool you do not currently need. Unload the dead battery, then unload the charged one from a less critical tool like a Flashlight, then slot it into the tool you need. |

How to Unlock the Battery Terminal
The Battery Terminal blueprint requires scanning two Battery Terminal fragments. The most reliable location is the Old Habitat, approximately 380 meters north of the Lifepod.
| Location |
|---|
 Fragment 1Inside the Old Habitat. Enter the northeast wing, find the long corridor connecting the two hab structures, and look to the wall on the right. The Battery Terminal is on the wall framed by yellow tubes. |
 Fragment 2Also inside the Old Habitat. Swim up the ladder opposite the connecting tube and search the wall to the west-northwest. It is near the Quaker Blackbox signal. |
How to Craft a Battery Terminal
| BatteryTerminal Recipe | Tool |
|---|---|
| x2 Titanium x2 Quartz x1 Copper Wire | Habitat Builder |
Build the Battery Terminal on an interior wall of your base using the Habitat Builder. It's best to place it near the hatch or entryways.
How to Recharge Batteries
The Battery Terminal holds up to six batteries at once. Interact with it and place your depleted batteries to be charged.
| Tip! | The Battery Terminal consumes 1 energy per second per battery being charged. Six batteries at once draws 6 energy per second from your grid. Make sure your base power can support the load. |

How to Craft a Power Cell Terminal
| Power Cell Terminal Recipe | Tool |
|---|---|
| x3 Titanium x3 Copper x1 Wiring Kit | Habitat Builder |
Similar to the Battery Terminal, you can construct a Power Cell Terminal using a Habitat Builder. The best placement for a Power Cell Terminal is near Moonpools.
How to Recharge Power Cells
The Tadpole uses Power Cells rather than standard batteries. To remove one, go to the top of the Tadpole and interact with the Power Cell socket.
Recharge Power Cells using the Power Cell Terminal, a separate facility from the Battery Terminal. Each Power Cell takes 10 minutes to fully charge.
Battery and Power Cell Recipes
If you need to craft extra batteries or power cells from scratch, here are the recipes.
| Item | Ingredients | Station |
|---|---|---|
| Basic Battery | x2 Copper x1 Acidic Raion Pouch | Fabricator |
| Power Cell | x2 Basic Battery x1 Strong Acid x2 Salt | Fabricator |
| Notice! | Subnautica 2 is in Early Access. Battery and Power Cell Terminals' function and charging times may change in future updates. |
