|It's fully charged with precious energy.|
|Season:||Spring, Summer, Fall|
In order to acquire a battery, during a thunderstorm you'll hear a particular sound, which means that one of your rods is now charged, pulsating with energy. There is no guarantee that your lightning rod(s) will be struck by lightning during a thunderstorm.
On the day after the storm, you'll acquire a battery pack from it.
Battery packs can sometimes be purchased from the Traveling Cart for 1,500-2,500g and can be sold to Robin at the Carpenter's Shop. Very rarely, a Battery Pack can be dropped by breaking boxes or crates in the Skull Cavern. They may also be dropped by Iridium Bats (5% chance).
