Thanks again. With all of your comments, I feel I will get something else 
tomorrow. Duracell's used to good batteries.

Paul,


Anything is possible, but no leaking as far as I could tell. That is always the 
first thing I look for.

I had some Duracell D's get a bit hot and bloat and ruin a radio.

I would bet some $ that Patrick's radio got pretty warm over time.

Thanks for the replies. These were not leaking, but that switch in Polarity 
really had me going. Maybe I should switch to Ray O Vac's or Energizers. I 
think I bought the Duracell's are Home Depot.

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

[Nick Hall-Patch]

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

Something odd happened tonight. I found my Super Radio II dead. So

my over 50 years in electronics I have never found that. The 
batteries are good Duracell. Has this happened to anyone else? With 
electronics I guess anything is possible. Two batteries were at 
about 1V, two were nearly dead and the two that reversed polarity 
were at about 1/2V. Fortunately the radio is fine. I replaced the 
batteries. This may be more common, but I have never seen it.
