The Battery Charger is an Appliance that recharges Batteries. It can be built using the Habitat Builder and placed in a Cyclops or a Seabase module. The player must scan two Battery Charger Fragments to acquire its Blueprints. These can be commonly found in Wrecks.
The Battery Charger can hold (and charge) up to four Batteries at a time. It features a display that shows the charge percentage of each Battery placed in it.
The Battery Charger uses Energy from the Cyclops or Seabase it is attached to recharge the Batteries that are placed in it:
- Charge time for a fully depleted Battery (100 energy): 11 minutes and 5 seconds
- Charge on battery increases by 9 energy (9%) per minute
- Seabase/Cyclops power drained by same amount as battery charge (recharge efficiency is 100%)
- Power drain is multiplied by number of cells being charged (all four cells is 180 per minute)
Ion Batteries (500 energy) can also be recharged. Charging 4 Ion Batteries at once will draw up to 180 energy
