[Milsurplus] Batteries for a PRC-77?

[Alan Tasker]

Somewhere on the web there is posted a copy of the "Load Up" book which 
discusses this subject, i.e. how to power many of the military portables. 
Maybe a search will turn up where it is, or maybe somebody else out there 
knows.

The PRC-25 needs 3 Volts for the Tx tube filament, and 15 Volts for the 
rest of the radio. The PRC-77 needs just the 15 Volts.

Magnesium batteries (BA-4386) are all over that famous auction site, some 
at reasonable prices, and some from sellers who are obviously gouging. Some 
people have had good luck with them, and some others have apparently 
received batteries from lots stored in wet and/or hot conditions. These 
particular ones are virtually useless.

Fair Radio Sales has out of date code but perfectly good Lithium batteries 
(BA-5598). They are selling for $3.50 each, two for $6.00, and $2.50 each 
in lots of some higher quantity like 10 or so.

S & G Photo in Philadelphia is on that auction site off and on under 
various names (depends on the actual clerk). They have been on the past two 
weeks, selling newer date code lithium batteries at $5.00 each in lots of 
12 I think it is.
