Bob,
I think you forgot to multiply by 24hrs/day for your annual energy
consumption, but your conclusion is still valid. Even at a ~440 mAH for
one year, the battery drain can be ignored for practical purposes. Most
of the current is consumed by the shunt regulator and the resistor
dividers
Just curious! What is your min battery voltage set to?

Ken,
The lithium batteries should be able to keep the clock going for quite a
few years. When the KX3 is off, the KXBC3 current should be around 50
to 75 microamps, depending on battery voltage, which comes out to
roughly 1.5 mAH per day.

Subject: [Elecraft] Kx3 lithium
I have had lithium batteries in my KX3 since I received it last Nov. I
use the batteries only to keep the clock alive and have never used them to
transmit or receive.. I use an external power supply to transmit etc, I now
find that if I try to turn on the rig using just the batteries the rig
