How to Unlock the Energy Cell in The Legend of Zelda: Tears of the Kingdom
Your adventure in The Legend of Zelda: Tears of the Kingdom begins not just with a sword, but with a battery pack. The iconic green Energy Cell on Link's hip is the key to powering the game's incredible Zonai devices, and unlocking it is your very first step toward creative freedom.
Link exploring the vast world of Hyrule.
This journey starts on the Great Sky Island. After completing the Ukouh Shrine, your next major objective is to find the In-isa Shrine, located in the island's southwestern region. Trust me, you'll want to make this your priority. The exact coordinates are 0027, -1503, 1408. Navigating the island's heights and chasms to reach it is part of the early challenge, but the reward is well worth the trek.
Upon successfully solving the puzzles inside In-isa Shrine and exiting, you'll be approached by a familiar face: the Steward Construct. This is the same friendly robot who gave you the Purah Pad at the very start of the game. Now, standing outside the shrine, this Steward Construct has a far more significant gift: your very first Energy Cell.
Don't rush past the Steward Construct! Take a moment to listen to its explanation. It will clearly show you the Energy Well—the battery indicator on your screen—and how it powers devices, which is fundamental knowledge for everything that comes next.
With the Energy Cell now equipped, you'll see a new Energy Well gauge appear on your HUD. This well is divided into segments; initially, you have one full battery comprised of three segments. When you activate a Zonai device like a fan or a wheel, this gauge will deplete, and it will slowly recharge when the device is off. This is your lifeline for building and exploration throughout Tears of the Kingdom.
You now have the power—literally—to start experimenting with Zonai technology. The vast world of Hyrule, its Sky Islands, and the mysterious Depths are yours to explore, one charged battery segment at a time. Let's go.
How to Find and Farm Zonaite in Tears of the Kingdom
The Depths beneath Hyrule hold the key to powering your Zonai creations—but first, you need to mine the fuel. In The Legend of Zelda: Tears of the Kingdom, Zonaite is the glowing green lifeblood of your battery upgrades, and the hunt for it is a subterranean adventure all its own.
Gameplay in Tears of the Kingdom.
Where to Find Zonaite: Your Primary Sources
The vast majority of Zonaite is found in the sprawling, gloomy underworld known as The Depths. You’ll access this region via massive Surface Chasms scattered across Hyrule (you’ll need the Paraglider for the initial descent). Once below, you’ll find Ore Deposits—sparkling black and green rocks that yield Zonaite when smashed. Use [Y] with a hammer-type weapon or explosives like Bomb Flowers for efficient mining.
Before your first trip into The Depths, stock up on Brightbloom Seeds. Throw or shoot them to create pockets of light, or attach them to arrows to illuminate your path in the permanent darkness.
For a safer, early-game source, head to the Mining Cave on the Great Sky Island. You can find its entrance south of the Chamber of Awakening at coordinates 0388, -1623, 1412. This cave is marked by mine cart tracks and contains up to fourteen Zonaite Deposits, giving you a solid starter stash without facing The Depths’ gloom.
When you’re ready to dive deeper, prioritize major mining sites. An excellent target is the Daphnes Canyon Mine in The Depths, located southwest of the Iayusus Lightroot at coordinates -1076, -0557, -0514. Areas like this are packed with deposits and are often guarded by enemies, so come prepared for a fight.
Understanding Zonaite Types and Farming Loops
As you mine, you’ll occasionally discover a rarer, more potent variant: Large Zonaite. This high-purity ore is a rare drop from Ore Deposits and a guaranteed reward for defeating Frox enemies in The Depths. It’s far more valuable for upgrades, so always pick it up.
Here’s the beautiful part for dedicated miners: every Ore Deposit you clear—along with every enemy—respawns after a Blood Moon. This event occurs roughly every 7 in-game days (or 168 minutes of real playtime). This means you can establish efficient farming routes through rich areas like the Daphnes Canyon Mine or the Great Abandoned Central Mine, and return after each Blood Moon to strip them clean again.
Efficient Farming Strategies
To build your Zonaite reserves efficiently, combine exploration with combat:
- Mark Your Mines: When you find a cluster of deposits, place a stamp on your map. After a Blood Moon, you can fast-travel back and collect everything again.
- Engage Enemy Camps: Monsters in The Depths often congregate around Zonaite nodes and will drop the ore when defeated. Clearing a camp nets you both the mined ore and the loot.
- Target the Frox: These burrowing mini-bosses are walking treasure troves, dropping both Large Zonaite and Large Crystallized Charges. Taking them down is a high-risk, high-reward farming method.
With these methods, you’ll transform the ominous Depths into your personal power plant. Stockpile that Zonaite—you’re going to need a mountain of it to become a true master of Zonai technology.
How to Exchange Zonaite for Crystallized Charges at Forge Constructs
You've braved The Depths and your pockets are heavy with Zonaite—now it's time to turn that raw ore into real power. In The Legend of Zelda: Tears of the Kingdom, this crucial next step happens at a Forge Construct, where your mining efforts are finally converted into the upgrades you need.
Find a Forge Construct
Your destination is an Abandoned Mine in the gloom. The most important one for this process is the Great Abandoned Central Mine in The Depths, located at coordinates -0821, -1940, -0523. It’s a central hub and the most reliable spot for exchanges. Inside, you’ll meet the Forge Construct, a specialized Zonai robot whose sole purpose is to process your hard-earned minerals.
Here’s what you can trade:
- Crystallized Charge: The standard currency for permanent battery growth. The exchange is simple: 3 Zonaite for 1 Crystallized Charge.
- Large Crystallized Charge: A much more efficient purchase. You can trade 3 Large Zonaite for 1 Large Crystallized Charge, and each one of these is worth 20 normal Crystallized Charges.
Think of it as trading up. While you can slowly convert stacks of regular Zonaite, prioritizing Large Zonaite for Large Crystallized Charges will save you an enormous amount of grinding.
The Fastest Way to Stock Up
Here’s the trick most guides miss: the Forge Construct’s inventory is limited, but you don’t have to wait for a Blood Moon to restock it.
Use this restock exploit at the Great Abandoned Central Mine to buy charges rapidly. After purchasing everything, manually save your game. Then, light a campfire, pass time until morning, and immediately load your manual save. The shop will be fully restocked, letting you buy another batch without waiting a full in-game day.
This method turns a slow trickle of charges into a rapid river, letting you convert a huge Zonaite stockpile in minutes instead of hours.
With a stash of Crystallized Charges secured, you’re holding the key to a bigger battery. The final step—turning them into permanent power—is just ahead.
How to Upgrade the Battery Gauge at a Crystal Refinery
You’ve mined the Zonaite, traded it for Crystallized Charges at a Forge Construct, and now you’re holding a stack of glowing green prisms. This is the final stretch in The Legend of Zelda: Tears of the Kingdom—turning your hard-won charges into permanent power. Head to a Crystal Refinery to make it official.

Where to Find a Crystal Refinery
You have two excellent options, each convenient for different stages of your adventure.
The first is on the Great Sky Island, right near the Nachoyah Shrine and the Room of Awakening. This is perfect if you’re making early upgrades and are already familiar with the starting area. Warp to the shrine, and you’ll see the Steward Construct ready to help.
The second refinery is much easier to reach once you’ve progressed. In Lookout Landing, head out the north exit. You’ll find it sitting on a large, fallen chunk of a Sky Island, conveniently placed near Josha’s office. This is your go-to hub for most of the game.
Making the Permanent Upgrade
Talk to the Steward Construct at either refinery. For every 100 Crystallized Charges you hand over, it will grant you one Energy Well—a single segment of your battery gauge. This is the only way to permanently increase your energy capacity in Tears of the Kingdom.
The construct can process multiple upgrades at once. If you have, say, 300 charges, you can get three wells in one conversation—no need to trade in batches of 100.
The Long Road to Max Power
Here’s the commitment: to reach the absolute maximum battery capacity, you need a staggering 4,500 Crystallized Charges. This translates to 16 full batteries (or 48 individual wells). The first eight batteries will fill out the green layer on your meter. Once that’s complete, a second layer of eight blue batteries unlocks, and your upgrades will start coloring that in. Seeing that blue bar fill up is the ultimate sign of a master engineer in Hyrule.
With your charges traded in, your Energy Cell is permanently stronger. You’re now ready to power more ambitious creations for longer, turning the vast world of Tears of the Kingdom into your playground.
Alternative Ways to Get Crystallized Charges in Tears of the Kingdom
If mining Zonaite is starting to feel like a day job, you’re in luck. The Legend of Zelda: Tears of the Kingdom offers far more exciting—and rewarding—ways to fill your battery. Forget just swinging a hammer; it’s time to go hunting.
Official illustration.
The Depths are your ultimate hunting ground. This vast, gloomy underworld is crawling with formidable mini-bosses that are practically walking treasure troves of Crystallized Charges. Every time you defeat a Frox, Battle Talus, Stone Talus, or Lynel down there, you’ll earn 20 Crystallized Charges and 1 Large Crystallized Charge. These foes respawn after every Blood Moon, giving you a renewable, high-yield source of upgrade materials. This is the strategy that will save you hours of mining.
For an efficient farming route, start at the Stakijat Lightroot in The Depths and head west toward The Floating Coliseum. You’ll find several mini-bosses in a near-straight line, and the coliseum itself houses three Lynels for a massive haul of 60 Crystallized Charges and 3 Large Crystallized Charges total.
For a truly epic payoff, seek out the Temple Boss Rematches. Once you’ve progressed through the Regional Phenomena quest and defeated the main story bosses, tougher versions of them will appear in The Depths, directly below their respective surface temples. Defeating each of these boss repeats for the first time rewards you with a chest containing a Huge Crystallized Charge, which is worth a whopping 100 normal Crystallized Charges—enough for one full battery upgrade on its own. With 12 of these bosses across four temples, that’s a potential 12 Huge Charges, giving you a massive head start.
Don’t overlook the Yiga Clan Hideouts scattered throughout The Depths. While exploring these enemy bases, keep an eye out for chests, as they often contain Large Crystallized Charges. It’s a great bonus while you’re already down there causing trouble.
Finally, if you’re following the main quest involving the Depths, you’ll eventually face Master Kohga. Defeating him also rewards you with a Huge Crystallized Charge, adding another 100-charge chunk to your total.
With these methods, maxing out your battery in Tears of the Kingdom becomes a thrilling adventure of conquest, not a tedious grind. Happy hunting.
Best Gear and Consumables for Battery Management
You've got the power—now let's talk about managing it. In The Legend of Zelda: Tears of the Kingdom, a bigger battery is only half the battle; the other half is knowing how to stretch every last drop of energy and get it back when you need it most. This final section covers the essential gear and consumables that turn you from a careful energy manager into a powerhouse pilot.

The Zonaite Armor Set: Your Permanent Power Boost
For a lasting upgrade to your energy efficiency, track down the Zonaite Armor Set. This set consists of the Zonaite Helm, Zonaite Waistguard, and Zonaite Shin Guards. When you wear the full set, you gain the 'Energy Up' bonus, which slightly increases your battery capacity. The real prize, however, comes from upgrading each piece by two levels at a Great Fairy fountain. Once you do, the full set bonus changes to 'Energy Recharge Up,' which significantly speeds up how quickly your battery refills after it depletes. This bonus is a game-changer for long journeys, letting you get back in the air faster after a quick pit stop.
On-the-Go Energy: Zonai Charges
Sometimes you need a quick top-up, not a permanent fix. That's where consumable Zonai Charges come in. You'll find these dropped by defeated Soldier and Captain Constructs across Hyrule and the Sky Islands. To use one, simply open your inventory, select it, and press [X] to restore a small amount of energy to your active battery cell. They're perfect for a minor boost to reach the next island or finish a puzzle.
For a more substantial—though temporary—power surge, seek out Large Zonai Charges. These are typically dropped by formidable Flux Constructs. Using a Large Zonai Charge (again with [X]) grants a period of temporary infinite energy, preventing your current battery from depleting for a short duration. It's the ultimate "get out of trouble" card when you're miles from land with a blinking red battery.
⚠️ Watch out: Both types of Zonai Charge only refill your current battery segment or provide a temporary buff. They do not contribute to permanent Energy Cell upgrades—that’s what Crystallized Charges are for.
Emergency Tricks and the Autobuild Tax
Two more critical tools round out your energy management kit. First, the Emergency Recharge: if your battery dies mid-flight, you can instantly restore all cells by quickly interacting with a Portable Pot. Just get near one and press [A] to cook—even while falling—for a full, immediate battery refill. Always keep a pot fused to a shield or in your inventory for true airborne emergencies.
Second, remember that your Autobuild ability, unlocked in the Great Abandoned Central Mine, has a hidden energy cost. If you're missing components for your saved schematics, Autobuild will automatically synthesize them using your Zonaite stash at a rate of 3 Zonaite per device. It's incredibly convenient, but it can quietly drain the resources you were saving for battery upgrades. Use it wisely.
With these tools in your belt, you're no longer just surviving—you're thriving. The skies and depths of Hyrule are yours to command, limited only by your creativity. Go build something amazing.
