You can make fancy mechanized contraptions in Tears of the Kingdom by using the many Zonai devices, such as fans and rockets. However, these devices will consume the charge on your batteries!
Batteries are also known as Energy Cells or Zonai Batteries in the game. Zonai devices will drain energy once you turn them on, but you can upgrade the batteries to allow these devices to be on for longer periods.
In this guide, we’ll go over how to expand your Energy Cells!
How to get More Batteries in The Legend of Zelda: Tears of the Kingdom
The only way to get more batteries is by collecting Crystallized Charges. You will need a total of 100 Crystallized Charges to get one extra segment for your batteries.
The easiest way to get Crystallized Charges is by exploring the Depths below Hyrule. You can find many chests in there that contain these items, as well as obtain them by taking down the bosses that roam the Depths.
You can get Zonaite by breaking down ores inside caves and the Depths. Mining Bokoblins also drop them when killed and they’re found all over the Depths. Bosses should drop Zonaite as well, but this is somewhat random.
Once you have at least 100 Crystallized Charges, you will need to head to a Crystal Refinery.
The easiest Crystal Refinery to reach is the one near Lookout Landing in Central Hyrule. We have highlighted it for you in the map above.
Give your Crystallized Charges to the Steward Construct and they will upgrade your battery with an Energy Well, giving you an extra segment.
Additionally, you can temporarily increase your batteries’ charges by consuming Zonai Charges.
