[Elecraft] Bat Err in KX3

[Don Wilhelm]

Ted,

The battery voltage was too low to start charging without possible 
damage.  Yes, NiMH batteries will self-discharge to the point of not 
being able to recover them.  Keep them charged, or you can loose them.
The KX3 internal charger requires a certain minimum voltage before it 
can start charging.  Bat Err is the indication that charging cannot start.

You might be able to remove the batteries and charge them using a 
different charger, but be aware that if they are deeply discharged, they 
may overheat during the process and destroy their future lifetime.

Yes, there is a rechargeable battery installed - it has worked just fine for years.  And yes, I did RTFM, about accessing the menu and the steps for readying the rig for charging (page 23, as I recall).  But that doesn't do it.  No matter what charge time I select, I get the same error message when I exit the menu.  "Bat Err."  Any ideas?  Could the batteries have died from having been ignored for so long?
