Quick answer
All Things How says Advanced Battery stores 200 energy and points the blueprint route to the Karakorum Power Plant area, where you scan two fragments. Subnautica2.gg lists two unlock paths: scan 2 Advanced Battery fragments or open a Data Box. Current blueprint pages list the Fabricator recipe as Conduit Crystal x1, Strong Acid x1, and Silver Ingot x1. Build Battery Terminal first if you already have a base, then rotate Advanced Batteries through it instead of crafting replacements. Keep Entangled Power Cell materials separate, because that route adds Gold Ingot and Troilite pressure.
Field notes for advanced power
Do the unlock trip like a dive plan
Advanced Battery is not a casual Copper craft. If Karakorum Power Plant is next, bring air, scanner power, and a route home before chasing fragments.
Keep the three rare inputs together
Conduit Crystal, Strong Acid, and Silver Ingot come from different rhythms. Put them in one small locker so the final craft does not become a guessing game.
Recharge before replacing
The point of a 200-energy battery is rotation. Once Battery Terminal exists, drained Advanced Batteries should cycle through it instead of becoming clutter.
Advanced Battery route
Do not treat it like a first-hour battery
Basic Battery is a Copper problem. Advanced Battery is a route problem. You need deeper materials, a safer oxygen setup, and a scanner trip before the recipe is even useful.
Scout Karakorum Power Plant with real dive prep
All Things How places the fragment route around Karakorum Power Plant and recommends a charged Scanner, Rebreather, and at least a Standard Air Tank. If that list sounds heavy, that is the page telling you not to rush it.
Scan fragments, but watch for a Data Box
Subnautica2.gg lists multiple unlock paths: two scanned Advanced Battery fragments or a Data Box. Scan the obvious wall-mounted gear, but do not ignore containers if the area gives you one.
Gather the recipe as a three-part checklist
The current recipe is Conduit Crystal x1, Strong Acid x1, and Silver Ingot x1. Put those in a small locker before crafting so the trip does not turn into five half-runs.
Use Battery Terminal to make it pay off
A 200-energy battery is much better when you can recharge it. Keep Advanced Batteries in the tools you use on long routes, then cycle drained ones through the Battery Terminal back at base.
Do not confuse it with Entangled Power Cell
Advanced Battery is the tool-upgrade battery. Entangled Power Cell is a later power craft with Gold Ingot and Troilite in the mix. Keep the two routes beside each other, not on top of each other.

Advanced Battery checklist
| Need | Why it matters |
|---|---|
| Scanner | Needed for the fragment unlock route. |
| Karakorum Power Plant prep | All Things How points the fragments to this deeper area. |
| Conduit Crystal x1 | Depth-gated resource used in the recipe. |
| Strong Acid x1 | Processor-chain material; do not spend it blindly. |
| Silver Ingot x1 | Processed Silver cost that makes early stock planning matter. |
| Battery Terminal | Makes the 200-energy battery reusable instead of disposable. |
| Entangled split | Do not spend Gold Ingot or Troilite here; those belong to the Entangled Power Cell route. |
Do not spend rare materials on a battery you cannot recharge
Advanced Battery is excellent, but the first one costs materials that also sit near upgrade and vehicle planning. If your base has no Battery Terminal yet, build the charger before turning rare parts into a pile of dead batteries.
FAQ
How do you unlock Advanced Battery in Subnautica 2?
Current blueprint data lists two paths: scan two Advanced Battery fragments or open a Data Box. All Things How points the fragment route toward Karakorum Power Plant.
What is the Advanced Battery recipe?
Current blueprint pages list Conduit Crystal x1, Strong Acid x1, and Silver Ingot x1 at the Fabricator.
How much energy does Advanced Battery have?
Subnautica2Hub currently lists Advanced Battery at 200 energy, double the Basic Battery value shown on the Basic Battery page.
Should you craft Advanced Battery before Battery Terminal?
Usually no. A Battery Terminal makes the upgrade much more useful because you can recharge expensive batteries instead of replacing them.
