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.
