You did not mention what power level you were running. To find a bad one you need to check the voltage under load. Even a bad one can look OK after a short rest with no load. -- View this message in context: http://elecraft.365791.n2.nabble.com/NiHg-batteries-How-do-I-test-tp7592271p7592328.h

I did check the voltage on each cell when depleted.. There is a sleeper or 2 in the bunch. -- Jim K9TF __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:El

Fred, I think you mean 1.2 or 1.25v nominal each cell. Jim NiMh don't take heat well. Sounds like you may have over charged. Did they get hot? 73 Another Fred, AE6QL -Original Message- >From: Fred Jensen >Sent: Aug 17, 2014 7:34 PM >To: elecraft@mailman.qth.net >Subject: Re: [Elecraft]

I figured that's what you meant. Not quite enough info to understand what is happening for you and what your charging situation is. NiMh cells are nominally at 2V. My experience has been that when they've reached the "End of Old," [a term coined by our kids to distinguish between Grandma and

I have 8 NiHg batteries and charged them for 16 hours. Charge lasts 5 minutes before KX3 goes dead. Minimum voltage is set for 8.4V. with a 13.6 volts 50 amp DX Astron supply max charge voltage get up to 10.6 VDC says my KX3. When checking the voltage independantly on each cell they all give me th
