Timmer Posted August 3, 2009 Report Share Posted August 3, 2009 Hi everyone. I was wondering if it were possible to use an A23 12 volt battery to power a 12 volt CPU fan. I know it probably looks like a "duh" question, but I know that certain batteries are good for certain applications, or they may last shorter/ longer in different situations. I'm asking because I currently have a setup I bought hear last summer which is 2 CPU fans ( 5 volt I think ) attached to a 4 AA battery box with the option to use a USB charge board. I can't remember who made it and I can't find the thread. It works pretty well, but I wanted to experiment with a 12 v fan or 2 to see how much difference there is. I don't really want to fill my AP with battery boxes, so I was hoping there was an application for these little A23 12 volt batteries. Thanks for any help, Timmer Quote Link to comment Share on other sites More sharing options...
gjw Posted August 4, 2009 Report Share Posted August 4, 2009 Not enough juice, I suspect. The A23 is rated at 55mAH to 50% so after supplying 55mA for 1 hour, the battery will be putting out only 6 volts. Not sure if you can find a 55mA 12v fan that will continue to work with only 6v but even if you did, it would only run for 1 hour. Quote Link to comment Share on other sites More sharing options...
NoVATie[Admin] Posted August 4, 2009 Report Share Posted August 4, 2009 Been there, done that . I clocked one A23 at about 45mins of run time. It's not that hard to wire up (1) 9-volt and (2) AAs in series for 12V and that will last much longer than the A23. Quote Link to comment Share on other sites More sharing options...
