[Milsurplus] looking for tadiran PRC660T batteries.

[goshawk]

hello list, am looking for the above batteries, or any ideas how I can get 
these radios powered up.
I have a few of them, and can find more radios very easily, but just can't 
find the actual batteries anywhere, so does anyone know where they are to 
be found, or has anyone managed to power one of these radios some other way 
using a more easily obtainable battery.
