Ever wanted to work a device that needs batteries, but the battery slot is too big for your batteries to fit? Well, here's a way to convert smaller batteries into larger batteries (in this case, converting AAA batteries into AA batteries).
Get your device that needs AA batteries and get your AAA batteries.
Grab some aluminum foil.
Place the AAA batteries into your device's battery slot. You will obviously see some extra space in the slot, since the AAA batteries are smaller than AA batteries.
Rip a piece of aluminum foil and curl it into a small ball. The size of the ball should be the same size of the extra space in your device's battery slot.
Place the aluminum foil in the gap. The aluminum foil should be on the battery's negative terminal, not the positive.
Finished. Your device will be able to work.
