Uses

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 rate: Increases by 9 energy (9%) per minute
Efficiency: Seabase/Cyclops power drained by same amount as battery charge (recharge efficiency is 100%)

Note on Ion Batteries: Ion Batteries (500 energy) can also be recharged. 9% charge per minute equals 45 energy per minute for one ion battery. Charging 4 Ion Batteries at once will draw up to 180 energy per minute.

If the seabase is out of power and the battery charger has one or more partially charged batteries, a message will display on the battery charger’s screen saying there’s no power, going to try again in five seconds. A timer is also present counting down from five. If power is still not restored at the end of the 5 seconds, the timer will reset.
