Re: [IRCA] Batteries in my Supper Radio II OT

[Nick Hall-Patch <nhp@xxxxxxxx>]

Anecdotal vague memory here:   yes, I believe I've seen this also 
with alkalines in series.   Is it possible that you might have mixed 
in older Duracells with fresh ones, Patrick?

If one cell in a series discharges down to zero volts faster than the 
others, likely due to starting at a lower initial voltage, apparently 
it is possible for good cells on either side to mildly reverse charge 
the dead cell.  But I've not seen anything authoritative stating 
that's the case, so call it an urban myth for now.

best wishes,

Nick
