AA batteries in AAA slot?

    I am wondering if it is possible to use AA batteries in AAA slots. Of
    course, I wouldn't be able to fit them in, but I was thinking that
    since AAA batteries are so hard to find I would just take some wires
    and tape and wire on some AA batteries instead. For example, my MP3
    player, TV remote, and 3rd party wireless Gamecube controller take AAA
    batteries, it would be very handy to use AA batteries with them
    instead. Would this ruin them? I'm thinking they might overload the
    circuits.

    Similarly with C or D batteries in AA or AAA slots.
     
  2. All the same voltage, so all can substitute for each other.
    Larger cells just sag less and last longer.

    Thanks for the confirmation. I knew they were the same voltage. I read
    the larger ones I listed are capable of considerably higher discharge
    rates, and I figured something bad could come of that.
     
  4. Their discharge rate depends on the load connected to them.

    To really sex it up, get some wooden dowel the size of the AAA, and stick
    a brass thumbtack in each end for contacts. Solder wires to the tacks, and
    stick the dowel in the AAA compartment, with wires to the other cells
    (which, like John said, can be AA, C, D, or even #6 if you're so inclined. ;-)

    On what planet are AAA batteries hard to find ?

    Well, not necessarily hard to find, but only available in ridiculously
    (comparitively) smaller quantities (I've only seen up to 4-packs, and
    right next to my computer is a 50-pack of AA batteries) and alot more
    expensive (a 2-pack of AAA is generally more expensive than an 8-pack
    of AA, same brand).

    Hmm.. Well, I've never even seen a store with that name. What's
    special? Large quantity, low price, or both?

    So buy a 4-pack of rechargeable AAAs, and a charger. You'll be amazed at how
    quickly it will pay for itself.

    I might do that if I come across such a thing in the future. That's a
    good idea. Until then anyway, C batteries and AA batteries shall be my
    preference.

    (I had rechargeable AAA and AA alkaline batteries once. They worked,
    but ended up a disappointment. Some leaked, and they permanantly lost
    capacity faster than any other kind of rechargeable battery I have
    ever had, even though they were advertised not to. They also only
    lasted about half as long as regular cheap alkalines per charge. I
    probably won't be going back to rechargeable alkaline in the future..)

    Your IP address appears to put you in Milton, Ontario, Canada. There are two
    Costcos in Mississauga, and another in Burlington.

    Both.

    Rechargeable alkalines suck. I'm not sure they're even made any more.
    Everything I've seen in the last five years or so has been NiCad or NiMH,
    either of which is way better.

    Yeah, funny how those IP locators work. They're never right, just
    close. I'm in Fergus.

    I went to that company's web site and they said the closest one to me
    is in Kitchener, 0 kilometres away. I think there might be something
    wrong with their distance calculations. Well, I don't know if I'll be
    going to Kitchener any time soon, so I think my current stock of C
    batteries and AA batteries are going to be more accessible anyway. Not
    to mention longer lasting. ^_^ Glad it was confirmed I could use them
    instead of AAA.


    Doug Miller wote:
    Agreed.

    Wikipedia has an interesting line about that "NiCad": "The
    abbreviation NiCad is a registered trademark of SAFT Corporation and
    should not be used to refer generically to nickel-cadmium batteries,
    although this brand-name is commonly used to describe all nickel-
    cadmium batteries." - http://en.wikipedia.org/wiki/Nickel-cadmium_battery
    So. NiCd. :p

    I think it's a valid question. Perhaps it could/should have been more politely
    phrased, but a valid question nonetheless. AAA batteries can be found at
    virtually any pharmacy, grocery, hardware, office supply, or convenience
    store. They're not "so hard to find" by any rational standard.

    I don't see him in quite so harsh a light. YMMV -- and you might want to spend
    a little time over in alt.hvac or misc.rural to see what nasty really looks
    like.

    Well, they're hard to find in larger quantities than 2. :p
