[Elecraft] Please DO NOT leave alkaline batteries in your KX3, KX1, or K1 for any length of time

[Edward R Cole]

I already decided not to install batteries inside my KX3.  But it was 
not primarily to avoid damage due to leakage of electrolyte.  Opening 
and closing the KX3 seems a little delicate to me.  One has to ensure 
the connecting wiring is intact and not being pinched.  I just 
decided to use an external sealed acid-gel battery if I need to go 
portable.  In the shack or mobile I will simply plug the power cord in.

I do have NiMH batteries inside my MFJ-269B.  I did try using 
alkaline batteries but they did not last long enough.  The 
rechargeable NIMH have been installed about two years with no 
issues.  I charge it using my 3A bench supply (current 
regulated).  2-4 hours on 14v does it.  No leakage issues.

Even with warrantees from manufacturers I would not trust alkaline's 
for long-term use.
