Re: [TenTec] Paragon II model 586 questions

["Bob McGraw - K4TAX" <RMcGraw@Blomand.net>]

The 9V battery used in the original Paragon is a standard 9 volt 
rechargeable battery.  You know the kind that has 2 snap terminals on top. 
The Paragon II has an internal CPU battery system which I understand the 
chip/device is no longer available.  I suspect they might be found as NOS on 
the surplus market but it makes one wonder if the battery is still good due 
to age.
The life of the original battery is projected as some 8 to 10 years per the 
manual.  In my case and the Paragon II I owned was some 15 years old and was 
still very reliable.  As to any suitable replacement or method to 
effectively bypass the internal battery, I'm not aware of such.
