How to Convert AA Batteries to AAA with Aluminum Foil
If you’re out of AA batteries, you can use a smaller AAA battery by folding up a small bit of tin foil and inserting it on one of the ends. Since AA and AAA batteries carry the same amount of voltage, this trick works effectively.
Why Are AAA Batteries Smaller than AA?
AAA batteries are smaller compared to AA due to the smaller amount of electrochemical material contained in them, resulting in a smaller electric charge.
Benefits of Using Consistent Battery Types
It is highly advisable to use batteries of the same type, brand, size, and expiry date in one appliance. Using different batteries can lead to differences in electrical capacity during usage, potentially causing issues such as over-discharging, leaking, or even explosions.
