One The Legend of Zelda: Tears of the Kingdom player has created a Zonai vehicle that allows them to zoom across the fields of Hyrule without using Energy Cells. These batteries enable Link to power up Zonai devices to keep them running for a period of time, which is determined by how many charges he has. While Link initially starts out with only one charge, he can upgrade them by trading Zonaite, a new material in the game, to Forge Constructs for Crystalized Charges and then visiting a Crystal Refinery in order to get more batteries in Tears of the Kingdom.
