Finding every hidden battery component in Horizon Zero Dawn is an essential milestone for players looking to secure the ultimate defensive advantage. These rare items are required to solve the puzzles within the Ancient Armory side quest and unlock the highly coveted Shield-Weaver outfit. Tracking down each specific ruin throughout Aloy's massive journey demands patience and careful observation during key story milestones.
Early Exploration and the Underground Ruins
The first power cell can be discovered very early in the game when Aloy explores the subterranean ruins she stumbled into during her childhood prelude. Returning to this location as an adult allows you to use your spear to break through stalactites blocking a hidden doorway. Snagging this item early prevents the need for tedious backtracking to the starting area later in the campaign.
A second crucial component is located within All-Mother Mountain immediately following the completion of the Proving ritual. While navigating the corridors of the bunker, you need to look for a small ventilation shaft next to a locked large door. Crawling through this opening reveals the battery sitting on the floor in a dimly lit side room.
Tracking Mid Game Main Quest Locations
As the narrative progresses, the third power cell becomes accessible during the main story mission titled Maker's End. Players must scale the massive Faro automated corporate tower to the very highest accessible platform. Before interacting with the terminal at the summit, look behind the structure to find a scaling path leading even higher up the broken skyscraper.
The fourth component requires deep infiltration into the frozen northern territories during the Grave Hoard mission. After completing the puzzles involving the multi-layered dynamic ancient ring mechanisms, look around the immediate exit corridors. The glowing green battery object is resting on a desk container just before you exit back out into the open world environment.
The Final Cell and Armor Activation
The fifth and final power cell is found within the ruins of GAIA Prime during the late game mission titled The Mountain That Fell. Instead of following the primary quest marker down the zipline, carefully explore the rocky ledge to the left side of the platform. A hidden path leads downward into a violet-hued room containing the last battery required for completion.
Once all five items are safely secured in your inventory tracker, return to the ancient bunker where the quest began. Inserting the batteries into the empty slots allows you to solve the final dual puzzle dials and unlock the ultimate armor cage. Equipping this technologically advanced outfit provides a rechargeable energy shield that temporarily absorbs all incoming damage from hostile machines.
