Not to be confused with the passive item, The Battery.
A 9-volt battery.
Isaac gets a battery embedded into his skull.
In Rebirth, if item requires single charge, changes it to cooldown. Cooldown time depends on item. Item starts to recharge after use only if there are enemies in room (to prevent abuse).
- Reduces cooldown time for The Candle to 1.2 seconds.
- When used with The Battery, allows for rapid use of held items.
- Synergizes well with Yum Heart, Book of Revelations, Prayer Card, and other items that have a long recharge time.
