I have read what I could find on the Elecraft web site and in this group's archives and am still confused about proper use and care of the K2's internal battery. I know that some owners install a new jack on their K2s to bypass the K2's built-in battery protection (a resistor and a diode?). However, I can't imagine that Elecraft would design a radio or one of its accessories that required modification in order to work properly.
I have two batteries for my K2 (both the Elecraft-supplied Power-Sonic models). One was receoved from Elecraft less than a week ago. I have not been able to charge either one to a voltage higher than 12.8 VDC yet. The original battery eventually got to 12.8 volts. The new one stays at 12.7 volts even after the K2 has been charging for a couple days on my SEC-1223 power supply (rated for 13.8VDC @ 23 amps). It seems that the battery must be charged at a voltage of 14.2 volts in order to avoid lead sulfate deposits from accumulating on its plates. On the other hand, I don't see any recommendations for chargers or power supplies that will provide that voltage at the proper amperage without risk of overcharging the battery. Also, I'd like to avoid buying a separate charger and power supply if possible. My question is whether or not there is a charger or power supply available that will power the K2 during home base use and also charge the battery properly when it is not being used. I apologize for my ignorance of battery technology and I'd appreciate any suggestions. Thanks! 73, charlie N1AOK _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list. Subscriber Info (Addr.
