[Elecraft] Best Batteries for KX-3?

[Don Wilhelm]

Dennis,

Although a bit expensive, AA size Non-rechargable lithium batteries will 
give longer life.
Rechargeable Ni-MH batteries will also last a longer time.  If you do 
not have the internal charger, you will have to remove them for 
charging, so carry a 2nd set of fully charged batteries.

Two hours seems like a short time for receive only.  If you are using 
alkaline batteries, use a good brand - the off-brand bargain batteries 
are often short lived.
