[R-390] Dry cell battery question

Sat, 05 Oct 2002 00:29:27 -0400

John,

These "B" batteries can be hard to find and quite expensive.  Fair Radio 
Sales has some mil surplus "B" batteries that are a little bit aged, but I 
assume at least partially serviceable.

  A friend of mine has made up B battery packs by connecting applicable new 
alkaline batteries in series.  Size and number of interconnections may be 
kept down by using 9 volt units.  Series strings may be paralleled for 
increased ampere-hour capacity (and increased cost).  A fresh alkaline cell 
has an open circuit voltage of 1.6v and still has considerable life left 
after discharged to 1.1v.  If you make the pack with a higher than required 
initial voltage longer service will result.

Discharge data fairly representative of most alkaline batteries can be found 
at duracell.com/oem/primary/alkaline
