AA to AAA battery? Please

[Sorgren]

To those that have no idea about batteries, the two most popular battery sizes for flashlights, radios, and so on:

 

AA - The thicker batteries (they have about 3 times the capacity as AAA batteries)

AAA - The thin batteries

 

So I seen instructions on turning an AAA to an AA, but my problem is different, I want an AA to fit in a AAA slot, because I have no AAA and besides, what´s better than having it last 3 times as much as using an AAA battery.

 

In my case I only need to fit 1 battery, it´s for an Altec Lansing Surround Sound earphone, that has this little device with a switch, that when you flick it on it boosts the sound much more and enables surround sound at the same time, I don´t mind it looking ugly after I mod it as long as it works and lasts longer.

 

Thanks in advance.

Wouldn't it just be easier to buy the batteries intended for it? :dry:

It would... But hey, for me batteries are a hard thing to come across with, because once i´m out, I either forget about them, have no money, or don´t go out at all.

Besides, I prefer the longer lasting batteries.

Sorry but I can't be serious on this thread either. LOL!

 

Just write down what you're gonna pick up in the store. It would be pretty bad if you forgot to eat as well, so I think you should put that on your list as well.

No!

 

Systems designed for a certain time of battery will not take a larger one. It's not as simple as it just lasting longer, but they have different power ratings as well.

So if you use a different type of battery than it is designed for, to small and it won't work at all, to high and it will most likely burn out or cause serious damage.

 

It's really not worth the risk eh?

Well? Since it is Xmas day. No stores are likely open? Okay! Here goes.

 

A little wire, card board, or if you have a broken toy that has a battery holder with the battery size you want, you can take that apart and use it, and some good tape would do.

 

Cut two wires about three inches long each. Choose wire with different colors. Strip the ends so you bare enough of the wire to tie, or solder, them to the point's of positive and negative inside the battery holder. They will dangling out of your head set, or whatever, container.

 

Cut the cardboard so you can make a little box for the battery; or if you have an old battery holder you managed to scavenge, tie in or solder, the other ends of the two wires into it. mounted so the battery contacts them inside appropriately. If you made a box, yourself be sure and mark the + and - upon the carton so you don't forget. I don't want you to have to go to the store on Monday to buy a whole new headset, or what ever.

 

Now tape, or glue the bigger battery box to your equipment somehow. And voila'! You have a bigger battery holder.

 

 

Those two batteries are safe to interchange.

 

CommanderCrazy has a good thought to consider though. Make sure you don't use something of higher amperage output or you could damage your device.

Ok I gave it a try, my earphones started to produce loud static sounds, I took out the battery and fixed it back together as it was, no damage done but lesson learned...

[Deleted54170User]

I have worked with electronics long enough to know that the AAA, AA, C, and D of the same manufacturing company, model, are the same in amperage. There should have been no problem.

 

Static is usually a sign of a low battery charge or a bad connection.

 

If you had gotten it in backward it would not have caused any noise. There can be none as no backward flow can occur, because there are parts that only allow the current (amperage) to flow in one direction.

 

Since I cannot see your battery, read the type on it, or see your work I can only draw two conclusions.

 

You battery was low, or, one, or all, of your connections for each wire were poor.

 

Either way you get, "Static."

 

Soldering is best, but twisting wire around points tightly enough and pressing them securely in place works. In the latter case the wires can work lose just from a tiny bit of movement.

[Deleted54170User]

One other fact you, "need" to learn is; which wire size is appropriate for your project. A proper coated wire, or twisted wires, are required to carry the current through to the components you want to have working. If the wire is too big or too small, the current (amperage) travels too slow so no response equals no sound to static. or too much amperage and fried smelly parts can occur.

 

The larger output supply a battery has can cause some items to over heat.

 

While the AAA, AA, C, and D size batteries wont damage your AAA device that will allow you to experiment safely.

 

So! Unless the wire you used was not connected tightly to the posts, points of contact, other than that they must be able to transfer the current (amperage) so the device receives the full potential of the battery power. Thin wires to thick wires carry the current at different rates.

Of course, in the time spent fidgeting around with all of that you could just mow a few lawns and buy the dang AAA batteries. If you like playing around with that stuff, more power to you. I'm not going to tell you to not take an interest in something. To me, at least, it just seems a little impractical.
