Bob - Someone may correct me on this, but I believe the original 14.1 to 14.2V specified was when early models of the K2 used an SB530 Shottky diode for polarisation protection. This was later changed to a 95SQ015 which provided a lower voltage drop. With that diode I run my K2 with 14.0V at the power input terminals and my original battery lasted for seven years with no leakage problems. 73 -- David G4DMP Leeds, England, UK ------ _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
