Tom,

It sounds like you may not have set the menu BAT MIN to 8.5 volts as recommended for NiMH batteries. The default before BAT LOW is displayed is 10 volts. 8 NiMH batteries will discharge quickly to below that 10 volt level, but the time between 10 volts and 8.5 volts will be much greater.

Look at page 36 of the manual for BAT MIN recommndations for several different battery types. The default of 10 volts works well with Gel Cells, which of course are external.

I’ve recently become interested in portable operating with my KX3. I’m using the 
Panasonic Enloop NiMH batteries.  I find that the batteries last for less than 2 
hrs.  Should I expect longer battery life. I just charged them on the external 
Panasonic charge and confirmed post charge voltage >1.3 volts.
