Power Cell (Subnautica)

The Power Cell is a crafted item in the advanced tree of the Fabricator. It is a large power source that depletes over time in Survival mode. It is used in the Seamoth and Cyclops. The Power Cell is also used in crafting the Mobile Vehicle Bay. To replace a Cell, click on it and choose to either remove it, leaving the space empty, or swap a fresh Cell from your inventory in its place. The removed cell can be recharged using a Power Cell Charger.
