Upgrading your Zonai Energy Cell in The Legend of Zelda: Tears of the Kingdom is essential for maximizing your exploration and device usage. While the process may seem a bit complex at first, this step-by-step guide will walk you through everything—from farming materials to refining and upgrading efficiently.

What Is the Zonai Energy Cell?

The Zonai Energy Cell powers all Zonai devices and recharges over time, much like your stamina wheel. It’s critical for traversal and creative builds. Here’s how to manage it:

• Zonai Charges: Instantly refill one-third of a battery segment.
• Large Zonai Charges: Temporarily grant unlimited energy—ideal for long-distance travel or intensive builds.

How to Farm Upgrade Materials

Zonai Charges

• Best source: Flux Constructs, powerful enemies typically found on circular sky islands.
• The stronger the Construct, the more charges it drops.
• Explore the skies and prioritize challenging Constructs for better returns.

Zonite

• Essential for upgrading, Zonite is harvested from:
  • The Depths: Mine Zonite deposits or defeat enemies to collect.
  • The Great Sky Island: Fast travel to Naturoya Shrine, then head to the nearby mining cave—deposits there respawn after each Blood Moon.

Converting Zonite into Crystallized Charges

To use Zonite for energy upgrades, you’ll need to convert it into Crystallized Charges:

Step 1: Visit a Forge Construct

Found in areas like the Great Abandoned Central Mine, Forge Constructs let you refine Zonite:

• Small Crystallized Charges: Cost 3 Zonite each.
• Large Crystallized Charges: Cost 3 Large Zonite, yielding 20 charges.

Step 2: Farming Trick to Restock

You can restock a Forge Construct’s inventory using this loop:

1. Buy all available charges.
2. Start a fire (wood + flint or fire fruit).
3. Sit until morning.
4. Reload the auto-save (triggered just before sitting).
5. Repeat to accumulate charges quickly.

Upgrading at the Crystal Refinery

Once you’ve gathered enough Crystallized Charges:

Step 1: Go to a Crystal Refinery

Refineries are found in places like:

• Lookout Landing
• Naturoya Shrine (Great Sky Island)

Step 2: Exchange for Energy Wells

• Cost: 100 Crystallized Charges = 1 Energy Well
• Each Energy Well = one-third of a full battery cell

To fully upgrade your Zonai battery (7 additional cells), you’ll need:

• 2,100 Crystallized Charges

Tips for Faster and Smarter Farming

• Blood Moon Cycles: Use these to revisit mined-out areas and reset enemy drops.
• Depths Efficiency: Target zones with multiple mine clusters.
• Duplication Glitches (if unpatched): Can significantly cut down on grind time.
