AAA Battery is a trinket.

Effect[]

  • If an activated item would regain its penultimate charge upon clearing a room, it is instead fully charged. This effectively reduces its charge time by one bar.

Notes[]

  • Does not affect items with only one bar of charge or those with automatic recharge.
  • Recharging an item by taking damage with 15►Habit Habit, the instant charge given by 15►9 Volt 9 Volt, or any source of charge other than clearing a room, will not activate the trinket's effect.

Synergies[]

  • Added in Afterbirth †15►Schoolbag Schoolbag: The trinket activates based on the primary item slot, but it grants an extra point of charge to the second item as well.
  • 15►9 Volt 9 Volt: If active item requires three or more charges, trinket gives an extra charge, effectively utilizing itself with 9 Volt.

Interactions[]

  • 15►The Battery The Battery: No effect on the second level charge.
  • Added in AfterbirthWatch Battery Watch Battery: Watch Battery triggering after clearing a room will also trigger AAA Battery, provided the activated item was missing exactly 3 charges prior to clearing the room.
