Reserve Tanks are expansions in Super Metroid. They add an extra energy reserve of 100 points per tank. There are only four in Super Metroid, giving Samus a maximum possible reserve of 400 energy points.
Reserve Tanks have two methods of usage: manual and automatic. When set to automatic, they will restore Samus's energy automatically when her suit energy reaches zero. When set to manual, they can be used at will through the inventory screen to restore energy.
