Mark, Having thought about this some more, I believe your point below is hitting the nail. My BAT MIN was still at the factory default of 10V, which obviously meant still lots of capacity. So the batteries were still quite full and thus got warm soon and repeatedly. Phew! I am not worried anymore. Thank you again! 73, Arno kg7bjm >> >>When should such batteries get charged, at what voltage level?
>>Don't let them go below 1v per cell...about 8 volts total on the KX3 display...8.5V would be safer. Elecraft recommends setting the BAT MIN menu to 8.5 V (KX3 Owner's Manual Pg. 36) to give you some warning that you need to think about recharging. This is about 1.06V per cell. The KX3 will shut down at 8 V which is about 1V per cell, very near the absolute minimum for NiMH chemistry. There isn't much energy left below 1.06v per cell, so running them below that level really doesn't give you much extra operating time. Some folks set the BAT MIN to 9V to give them more warning and plenty of time to finish their QSO and shut the station down. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
