Energy Tanks (エネルギータンク Enerugī Tanku ) increase Samus's maximum energy by 100. They appear in almost every Metroid game and are vital for survival. While some can be found in open areas and are easy to obtain, some are well hidden and require excessive searching to find. The more Energy Tanks Samus collects, the more damage she can withstand before dying. The traditional number of Energy Tanks found in a Metroid game usually hovers around the fourteen mark, although it has gone as low as five (in Metroid II: Return of Samus), and to as high as twenty (in Metroid Fusion). In Metroid Prime 3: Corruption, two Energy Tanks are unavoidable, as an Energy Tank must be used to activate Hypermode, a function required several times throughout the course of the game. In both Metroid and Metroid II: Return of Samus, there is at least one extra, unusable Energy Tank. For Metroid there are eight Energy Tanks, but Samus can only use six; and in Metroid II there are six Energy Tanks, but Samus can use only five.
In Metroid: Other M, Samus only obtains five actual Energy Tanks. Samus must acquire the rest by collecting Energy Parts, which are pieces of Energy Tanks. Collecting four of them creates a new Energy Tank for Samus to use. There are also E-Recovery Tanks, which increase the amount of energy Samus can restore with Concentration. Energy Tanks are stored in holdings and have a "purplish-red" color, although sometimes the actual tank itself can be collected. The tank in storage is 300mm long, and the tank alone is 500~600mm long.
The Energy Tanks increase the power level available to your Suit's defense screens.
Each Energy Tank increases your Suit's energy by 100 units. The more energy your Suit has, the longer you can stay alive.

Increases the POWER SUIT's maximum energy storage capacity by 100 UNITS.
- Captain N: The Game Master (Money Changes Everything): Samus takes a hit from three Gamets and Kevin prevents her from exploding by crossing the Fire-Sea to grab an Energy Tank for her.
- Mario & Luigi: Superstar Saga (2003, Game Boy Advance) (Samus was intended to appear at Starbeans Cafe, among other Nintendo characters, during a scripted event. Dialog remains in the game's code-"Cashier: Whoa! A power outage? Yikes! Samus Aran! I see you're rocking and rolling as usual! ...Looks like your energy tanks are empty! Sorry, but can't you give your Hoolumbian to Samus? Oh! Feeling better?" She would then give the player an Energy Tank in exchange for the drink. Ultimately, most of the items from Nintendo characters were replaced with similar ones in the final game, and the Energy Tank became a Power Grip accessory.)
