Hi All,



I am trying to find a double A (AA) battery replacement power supply that runs from a 12v socket. I cannot for the life of me remember what these are called, thus my Google searches have been fruitless. 



If somebody knows where to find such a thing please let me know. I have two Lightspeed headsets that each take a pair of AA batteries for the noise canceling function. I want to find some of these AA adapters and make it a more permanent installation.



Thanks very much,



Mike

Hi Mike,



Check out Thomas Distributing for most of your small battery and charger needs.  I've been buying from these guys for years with no problems whatsoever.  Go to Shop By Category and click on Chargers, then Chargers by Battery Size, then select one of the four categories for AA batteries.  I'll endorse the Maha brand of chargers, since that's why I have and know.  I've had the MH-C204F for ~8 years with no problems whatsoever.  It's not listed anymore, but if you select AA-AAA Chargers, you'll see Mahas listed.  If I had to buy a AA charger today, I would select the Maha MH-C204GT (AC Adaptor) or MH-C204GT-DC (AC and 12V DC Car Cord Adaptor).  You, of course, need the latter for 12V usage.



Also, check out Thomas Distributing's AA NiMH battery selection.  I see that they now have 2850 mAH batteries.  Mine are 8 year old GP 1800 and 2000 mAH batteries, and they do just fine on cross-country trips.

Henador,



THanks for that tip on chargers. It is a good source, but not exactly what I am looking for. 



I want to replace the AA batteries with an adapter that slots into the spot that the two AA normally go. Then that is wired to a 12v socket plug. That way I never have to worry about charged batteries. Just plug in and go. I know this thing is out there, I've seen them. Now I just cannot seem to find them. And I remember there were models for a 9 volt replacement as well as AA.



Thanks again,



Mike

OK, finally found them.  'battery eliminator'.  Kind of like Ahnolad, the Eliminator.

  I know what you are asking, you want to connect a 12 volt cigarette to 3 volt power supply to your head-set through some dummy AA cells (with wires sticking out them). 

   

  Well you could just solder or clip some wires in and route them out to a plug and the power supply. I am not sure they make AA with wires sticking out of them. You could make them but that is a lot of work for little gain. Do you wnat extra wires running all over and a 12v to 3 v power supply going all the time. 

   

  Mike if I where you, I would by a bunch of rechargeable nickel-metal hydride batteries, abbreviated NiMH. [quote][b]
