It is not compatible with AA, AAA, or other battery sizes. Please ensure your 18650 cells fit within the holder's slot dimensions before purchasing.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between the 2-slot and 3-slot versions?\u003c\/h4\u003e\n\u003cp\u003eA: The 2-slot version connects batteries in a parallel circuit, which maintains the same voltage while doubling the capacity. The 3-slot version connects batteries in a series circuit, which adds the voltages of each cell together for higher total voltage output — ideal for powering devices that require more voltage.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are batteries or wires included with this battery case?\u003c\/h4\u003e\n\u003cp\u003eA: No, this listing includes only the plastic battery holder case.
