    You will obviously see some extra space in the slot, since the AAA batteries are smaller than AA batteries. [3]

    The size of the ball should be the same size of the extra space in your device's battery slot. [4]

    The aluminum foil should be on the battery's negative terminal, not the positive. [5]

    Your device will be able to work.

  • Question
    Does it have to be aluminum, or can it be another metal?
    Community Answer
    It can be certain types of metal, but not all. Aluminum is the best because it can fit into small areas and it's foldable.

  • Question
    Does this really work? When I tried it with my remote, it turned on and then off again.
    Community Answer
    You have to make sure that the foil is snug between the battery and the end, tightly wrapped, and the battery isn't loosely attached.

  • Question
    If I touch the foil while the device is on, will it shock me?
    Community Answer
    No, it won't shock you. The power in AA/AAA batteries is not enough to shock you.
