AA to AAA battery? Please

[Deleted54170User]

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.

 

Hey! I have a project that needs doing. I have to remove dirt down 3 feet deep from my entire lot so I can restore the land to its pristine condition. Care to show up?

 

This coming Spring I will provide dust masks so we don't breath the Arsenic and Lead, in their dust sized, particles that may be contributing to my flights of fantasy now. One of which is that, it would only take about fifteen minute's to correctly make a battery holder, once the correct wire size was tightened down on the posts so that they would not slip. Then an AA, C, or a D battery could be used for the device.

 

Running around the house to find some scrap wire that would work might take as long as it would take have accomplished getting the lawn mower started after sitting all Winter.

I have been working in electronics for over 45 years. The amperage of the battery does not matter - just the voltage.

Amperage is how much power is available in the battery - ie. if a battery is rated 1 amp, then it will supply power at that voltage up to 1 amp safely. Any device that uses less amperage (current) will work fine.

 

If a device is rated for 1.5 volts (normal AA & AAA battery voltage) , it does not matter how much the amperage rating of the battery is as long as it is less than the amperage rating of the battery. An AAA battery will have a lower amperage rating than a AA battery. So it can supply less power at the same voltage.

 

However if you place multiple batteries in series (end to end) the voltage adds - so 2 1.5 volt batteries end to end (positive on one battery connected to negative on second) will give you 3 volts. take the same 2 batteries and connect them in parallel (both batteries face the same way, with both positive ends tied together and both negative ends together) you will still get 1.5 volts, but will have doubled the amp rating - usually means you can run a device that requires more amps than one battery can supply.

 

Typical battery power capacity chart from: http://www.techlib.c.../batteries.html

mA = milli Amps - mAh = milli amp hours - No this does not mean the battery will last 12,000 hours. :rolleyes:

 

Hope this helps.

Why couldn't the OP simply have purchased rechargeable batteries in the first place? That would solve both his time and money problem. Also, don't most devices come with their own chargers anyway? The only device I have that takes batteries is my wireless mouse, which I replace with dollar store AAA batteries every 3 months.

 

I googled "Altec Lansing Surround Sound earphone", and I think you'd probably be better off with blue tooth instead, since most bluetooth devices either come with a charger, or can simply be chared by a USB port.
