fozzies Posted January 29, 2012 Share Posted January 29, 2012 U need to look at the data sheets on each device and add up their quiescent current. take the resulting figure and multiply it by the number of hours you require Link to comment Share on other sites More sharing options...

sixwheeledbeast Posted January 30, 2012 Share Posted January 30, 2012 As a rough idea I would aim to put no more than 560mA standby current on a 7Ah to get 12 hours standby. Link to comment Share on other sites More sharing options...
