AAA Battery

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 (Habit) Habit, the instant charge given by (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 †)(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.
• (9 Volt) 9 Volt: If active item requires three or more charges, trinket gives an extra charge, effectively utilizing itself with 9 Volt.

Interactions

• (The Battery) The Battery: No effect on the second level charge.
• (Added in Afterbirth) 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.
