With this trick you can turn a small battery into a large one

Different electronic devices often require batteries of different sizes. However, you don’t always have the right size at hand. But with this simple trick you can turn a small battery into a large one.

Although rechargeable batteries have been part of everyday life, conventional batteries still have a right to exist. Because especially in devices that do not consume so much power, they are definitely the more sensible option.

The best example: remote controls, children’s toys and alarm clocks. As a rule, they even last for several years with a set of batteries. But at some point they too have to be exchanged. The search for suitable replacement batteries then often begins. But sometimes you don’t have the right size ready.

With this trick you can make the right battery

With a simple trick you can turn a small AAA battery into the next larger AA variant. All you need is the appropriate number of batteries for your device and a piece of aluminum foil.

Because aluminum is inherently a good electrical material Director. The metal has three delocalized electrons in the valence shell that move randomly from one atom to another. With a piece of aluminum foil and a little tinkering talent, you can quickly get your devices up and running again – even if you don’t have the right battery size at hand.

Battery trick: This is how AAA becomes AA quickly and easily

To “grow” a small battery, first insert your AAA battery into the designated compartment in the device. The trick works best if you push the positive pole into the small spring as far as it will go. The negative pole should therefore be exposed.

Now take a piece of aluminum foil and fold it into a small, compact package. This is now your electrical conductor to bridge the gap between the contact on the negative side and the battery. This is how you create the flow of electricity. Your device should now work even though you did not insert the correct battery.

Battery trick only as a temporary solution

Importantly, this household hack should only be a temporary solution. Because the smaller battery has less energy storage due to its size and nature. It is no coincidence that the manufacturer of your device specifies one or more larger batteries.

However, the aluminum trick will help you bridge the time until you get around to buying the right battery and inserting it into your device.
