Can't Find Batteries in Subnautica

Batteries are crafted electronics that power early tools. If a Seaglide or Scanner is empty, the fastest fix is two Acid Mushrooms plus one Copper Ore at the Fabricator, not a Battery Charger hunt.

LAST CHECK

ANSWER LOCK // QUICK RESPONSE

Craft one Battery at the Fabricator with two Acid Mushrooms and one Copper Ore. The Battery Charger is optional later; it is not required to make the first battery or power early tools.
