Richard,The one place that the KX3 Owners Manual seems to be short on is an explanation of the various KXBC3 Charger error messages. They are all in the KXBC3 Installation and Operation guide which most owners of factory built KX3's never look at. There needs to be a note to look up battery charge related error messages in the KXBC3 manual, or merge all error messages into the KX3 owners manual. (Ron, AC7AC: I am not a Tech Writer, so this is just a suggestion).The KXBC3 Installation and Operation guide says that the BAT ERR message is due to "Battery missing or battery voltage out of range due to a fully charged pack or a defective or missing cell..."I suspect your cells that drifted down to zero volts look like "defective or missing cells" to the KXBC3. They would certainly cause the voltage to be out of range resulting in the KXBC3 issuing that error message.I don't have much experience with regular NiMH cells (as opposed to Low Self Discharge NiMH cells), but I did try a set of them (Rayovac) a month or so ago with poor results. After a couple of weeks of no usage, I had to recharge them. One had dropped well below 1v, and the others varied some, but were near 1v. In my case, the KXBC3 was able to recharge them, but I wondered what would happen if I had left them in the KX3 longer until the voltage dropped well below 1v per cell. I think I know now, based on your experience.I am certain you will be much happier with the Eneloops. There are a couple of other good brands NiMH cells out there, but you must be certain they are Low Self Discharge cells unless you are willing to recharge them often.MarkKE6BB From: Richard Gagnon [email protected]>Sent: Wed, Oct 16, 2013 at 4:40 PMTo: [email protected]>Subject: [Elecraft] kx3 internal batteries questionI have a question about the batteries in my KX3. I purchased and installed 8 Anasman 2850 NiMH batteries in the KX3 andhave used the radio successfully on these batteries for several months,including several recharge cycles with the KX3 internal charger. I lastused the KX3 several months ago, so the batteries were understandablydead when I went to try it out the other day... ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
