[Milsurplus] Duracell Coppertop battries

[John Watkins]

Hi John,

That is what my research on the Duracell showed.  They were great batteries
when Mallory made them and went downhill almost instantly when the company
was sold. I have been buying Energizer batteries for the past few years,
and tried the Coppertops again last year.  Got them at Cosco and put them
in my Simpson 260 meter.  I then found a few months latter that the
batteries still in the pack were leaking and took them back.  The manager
and I then went and looked at the display and found leaking batteries
there.  He pulled them and gave me a refund.  I had forgotten that I had
put them into the 260 until yesterday, my bad.
