[Elecraft] KX3 battery problems

[Don Wilhelm]

Robin,

Can I assume those rechargable batteries are NiMH type?  While they are 
good, they do have a lifetime that is expressed in number of recharge 
cycles.  Personal experience has shown that the life of such batteries 
is in the vicinity of 3 to 4 years.

It is often that the no-load voltage of a battery is OK, but as soon as 
you draw any current, it goes "belly up".  You can monitor the voltage 
of the pack with the KX3 alternate VFO B display.  Try to see the 
voltage after the KX3 shuts off.

73,
