"A large storage battery. Insert into a battery box to use."
Battery is a key item in Resident Evil 7: Biohazard.
The Battery is used to restore power to the elevator in the testing area. Using it will trigger the event where the elevator lowers and releases a Fat Molded.
- Unlike any other items in the game, examining the Battery brings up the message "Battery" despite it not being written on the item itself.
