|This article is about the pickup. For the item, see The Battery. For other uses, see Battery (Disambiguation).|
Lil' Battery will fully charge Isaac's activated item upon pickup.
Lil' Battery will only charge the currently held active item. Holding two actives (e.g. with Schoolbag) will not charge both items upon pickup.
A Micro Battery provides two bars of charge for Isaac's held active item when picked up.
A Mega Battery will charge Isaac's activated item twice. It will double charge items with over 6 bars.
A Golden Battery completely recharges Isaac's held item, but also deals a full heart of damage. Another golden battery will spawn in a random room, but it is not shown on the map until discovered.
