  • If Isaac has 15►The Battery The Battery and the recharge time for his held item is less than 6, Lil' Battery will overcharge the item for the remaining charges left in the Lil' Battery.
  • 15►Holy Mantle Holy Mantle and similar effects will block the damage from the Golden Battery, allowing for infinite usage of active items on that floor.
  • Golden Batteries can re-appear in undiscovered rooms, including both Secret Rooms.
