Learning how to get more Zelda Tears of the Kingdom battery upgrades is something not especially well explained in the game, as the process involves finding Crystallized Charges and giving them to a Crystal Refinery, neither of which are particularly intuitive ideas. Still, once you understand the basic ideas it's actually not too difficult to get battery upgrades and increase the size of those batteries for a longer running time on all your vehicles - though obtaining the raw Crystallized Charges in the first place is a little more of a challenge.

With that in mind, we'll go through everything you need to know about how to get more batteries, or at least to upgrade the batteries you already have, in Legend of Zelda: Tears of the Kingdom below. Keep in mind that you can also consume Zonai Charges from your inventory to get temporary expansions and refills on your battery, but these don't last long and aren't as good as a full-fledged upgrade.

To increase your battery life and power in Zelda Tears of the Kingdom, here's the basic process laid out clearly:

  1. Find Crystallized Charges across the map
  2. Take those Crystallized Charges to the Crystal Refinery in Lookout Landing
  3. The Steward Construct will turn those Charges into Energy Wells
  4. Your battery can now run for longer!

The Crystal Refinery is found just North of Lookout Landing, marked on the map and just above the Northern wall of the outpost. There's a little rock with a machine and a Steward Construct on top - once you have 100 Crystallized Charges or more, head up there and talk to the Construct.

The Construct will turn your Charges into Energy Wells, which are the specific units of power your Zonai Energy Cells use. 100 Crystallized Charges is turned into one well, with three Energy Wells per "battery" of power. Of course, that doesn't mean much if you can't find charges.

How to get Crystallized Charges

Crystallized Charges in Tears of the Kingdom can be obtained in the following ways:

  • Defeating certain bosses like Flux Constructs and Frox
  • Found in chests in abandoned mines in the Depths
  • Purchased from Steward Constructs in Forges in the Depths
  • Found in chests in Yiga Outposts in the Depths

Clearly the Depths are the main place to go if you want Crystallized Charges. We certainly recommend empting the supply of any Steward Constructs refining Crystallized Charges - you can buy their stock not with Rupees, but with Zonaite, which is also readily available in deposits down there (though we do have a Zelda Tears of the Kingdom Rupees guides if you are feeling short of cash). Basically, the longer you spend in the Depths, the more likely you are to come up with a load of Crystallized Charges - and therefore battery upgrades. If you want help with the whole Zelda Tears of the Kingdom Depths area - which is fair, it's pretty dangerous - our guide will help lay it out for you.
