[Elecraft] Why are the batteries internal to the KX3?

[Don Wilhelm]

Chuck,

How long are you "not using" the KX3?  If the time is not several weeks, 
the batteries can stay in.  For battery maintenance, if you have the 
KXBC3 option installed, and Low Self Discharge NiMH batteries installed, 
just connect to a power source with enough voltage and do a maintenance 
charge on the batteries every couple weeks.

You can always remove the batteries and use an external power source. 
Of course, if you have the KXBC3 option, the RTC will not keep time with 
the batteries removed.

The KX2 internal battery pack can be used external to the KX3 - just 
plug it in.  Get the KXBC2 to charge the KX2 battery pack.

73,
