[Elecraft] [K3] Real Time Clock Battery replacement

[rick.ag6ay at gmail.com]

It all depends on the RTC current.  A nice graph of expected life vs current
(uA) for a number of CR cells is in
http://www.varta-microbattery.com/applications/mb_data/documents/sales_literature_varta/HANDBOOK_Primary_Lithium_Cells_en.pdf

I had my K3 for 3 yrs when I upgraded the synth cards and I did replace the
CR2032 on general principle. 

Cheers
