If you’re out of AA batteries, did you know you can use a smaller AAA battery by folding up a small bit of tin foil and inserting it on one of the ends? It totally works since AA and AAA batteries carry the same amount of voltage.
Can you use tin foil in place of batteries?
Wads of aluminum foil cannot actually extend the life of the batteries. Their life is determined by chemical reactions inside the cells, and nothing that happens outside the cells has an effect on the internal chemistry.

Does putting batteries in the freezer recharge them?
In short: no. While cold environments help maintain battery life, refrigerators and freezers are not safe to put batteries in. The moist environment will cause condensation on the batteries. This in turn will lead to rust or other damage.
Can you use Triple A instead of Double A?
AA and AAA batteries are both 1.5V nominal (for disposable) and 1.2V nominal for rechargeable (usually NiMHs.) As long as the current draw doesn’t exceed the AAA’s ability, you can use a AAA in place of a AA by bridging the gap (may need some padding around it as well to keep it aligned.)

Keep paint off doorknobs
When you’re painting a door, aluminum foil is great for wrapping doorknobs to keep paint off them. Overlap the foil onto the door when you wrap the knob, then run a sharp utility knife around the base of the knob to trim the foil. That way you can paint right up to the edge of the knob.
Is AAA the smallest battery?
WHAT IS AN AAA BATTERY. AAA batteries are smaller than AA battery cells. A single cell has a dimension of 44.5 mm in length and 10.5 mm in diameter.
Why is there no single a battery?
In 1924, industry and government representatives met again to figure out a naming system for all those cells and batteries they had just standardized. They decided to base it around the alphabet, dubbing the smallest cells and single-cell batteries “A” and went from there to B, C and D. There was also a “No.
Why are there no B batteries?
Since then, the ANSI standard for batteries has been revised numerous times as battery technology has evolved. Why it appears there is no B (or A, F, etc.) anymore is simply because those particular battery sizes never really caught on commercially, at least on the consumer end of things.
How can dead batteries be reused?
Don’t Dispose, Reuse: 5 DIY Projects Using Old or Dead Batteries
- DIY Solar Powered Generator.
- A Portable Rechargeable Lighting System.
- A Portable Mini Fan.
- Cool DIY Flashlight with 9V Batteries.
- A DIY Magnet Holder.
Can you recharge normal AA batteries?
Can alkaline batteries be recharged? Only batteries that are specifically labeled “rechargeable” should be recharged. Any attempt to recharge a non-rechargeable battery could result in rupture or leakage. We recommend that you use NiMH Duracell rechargeables.
What household items use AA batteries?
Portable radio, digital camera, wireless keyboard, wireless mouse, cordless phone. Electronic toys, TV Remote, Radio, Clocks, Motors, Transmitter used for quadcopter, RC Car, etc, Some drillers.
How can I make my battery last longer?
How to Make Disposable Batteries Last Longer
- Turn the Power Off When You’re Not Using Items.

How do you install AAA batteries?
The polarity of batteries is what helps them supply current to a device. The plus sign, or +, indicates the positive terminal. On AA, AAA, C, and D batteries, the positive end should be slightly raised. The negative end of the battery should be flat, and it may or may not be marked with a minus, or -, symbol.

At 150 nanometers wide, the nano battery is hundreds of times thinner than a human hair and more than 60,000 times smaller than a AAA battery. How many “A”s is that? The little battery, developed at Rice University, is actually a cross between a battery and a supercapacitor.
How are batteries sized?
Different Battery Sizes
Generally, the larger the battery is, the more capacity it has for energy storage. So even though a big and small battery are both rated at 1.5V, the big battery stores more energy and provides a longer battery life.
