Missile Battery

From Wikitroid, the Metroid wiki

Essentially the precursor to the Missile Stations of Super Metroid, the Missile Battery reloads all of Samus' entire missile payload upon contact. However, unlike the aforementioned Missile Stations of Super Metroid, these exceptionally large missile canisters are usually found in remote locations within the regular playing field.

Currently, Metroid II: Return of Samus is the only game to feature this item.
