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 Sacred Lands
The journey begins near the starting area where adult Aloy can revisit the subterranean cavern she fell into during her childhood tutorial. Navigating deep into these ancient ruins allows you to find a blocked room sealed by stalactites and stalagmites that must be broken down with a spear attack. Clearing this path reveals the first component sitting visibly on a desk inside the abandoned office complex.
A second crucial piece can be discovered inside the All-Mother Temple right after completing the intense events of the Proving storyline. Before following the matriarch out of the main hall, players should carefully inspect the surrounding corridors to locate a small ventilation shaft. Crawling directly through this hidden tunnel grants access to a locked room holding the battery component on the floor.
Climbing the Tall Towers of Faro and the Grave Hoard
As the narrative pushes further out into the frozen wastes, players will need to scale the towering corporate remnants at Maker's End during the main quest. After completing the dialogue objectives at the absolute peak of the skyscraper, look closely for hidden yellow handholds leading even further up the spire. Scraping past the ruined office framework rewards the adventurous climber with a third hidden power cell waiting at the very top.
The search continues inside the frozen military complex known as the Grave-Hoard, which unfolds during the next major chapter of the main campaign. After successfully unlocking the second combination lock puzzle, you will need to watch the side chambers closely as you walk down the primary corridor. Dropping to the ground right behind the newly opened bulkhead door is the fourth essential collectible needed for the bunker.
Reaching GAIA Prime and Activating the Armory
The final component is locked deep within the ruins of GAIA Prime and can only be accessed during the mission titled The Mountain That Fell. Before taking the final zipline out of the ruined facility, turn around to spot a hidden rocky ledge marked with subtle climbing markers. Scaling this wall leads to a purple-lit side cavern where the fifth item rests quietly on a shelf in the back chamber.
With all five components securely gathered in your inventory, you can head directly to the ancient bunker located between the Nora lands and Carja territory. Slotting these batteries into the two distinct wall interfaces allows you to solve the final rotation dial puzzles and release the clamps. Equipping the resulting armor provides an active force field that absorbs massive damage before depleting during intense battles.
