Batteries are stationary installations able to store and release electrical power.

Function

Batteries can be useful for stabilizing the submarine's power. They can absorb excess power when the Nuclear Reactor overproduces and threatens to overload and damage connected devices. When the power supplied by the reactor is less than the power required by the connected devices (be it because the reactor doesn't produce enough, is not connected to the device anymore, or is destroyed), batteries can provide back-up power for a substantial amount of time depending on the amount of power they have stored. This allows maintenance to be safely performed on the reactor in the event of an unforeseen problem.

Batteries have 3 inventory slots for recharging Battery Cells or Fulgurium Battery Cells.

Note: battery cells will be recharged as long as the battery has at least 1 kWmin of charge, even if it is not connected to the grid.

The recharge rate can be changed in game through the UI or wire signal to the set_charge_rate pin. A low recharge rate reduces the power load on the reactor, but takes longer to refill after a load spike.

Decay rate

Batteries decay at a constant rate, regardless of whether or not it is connected to the grid. However, they deteriorate significantly faster when submerged in water.

Shuttle Batteries are invulnerable to damage (including explosions and submersion in water) and therefore do not need to be repaired.

Connection panel

Connection Panel for Battery Hover over pins to see their descriptions.

power_in set_charge_rate Stores inputted power in the battery. Sets the battery's charge rate to the inputted value. power_out charge_out charge_% charge_rate_out condition_out load_value_out power_value_out Outputs battery's stored power to anything connected. Outputs current amount of stored power. Outputs percentage of the currently stored power. Outputs current charge rate. Outputs the Battery's current condition. (0-100) Outputs the Battery's load (required power). Outputs the Battery's power (supplied power).
