[Elecraft] Source of NiMH cells?

[Matt Zilmer]

Hi Mark,

You caught me in the middle a battery research project (day job) and I
found some dirt on Rayovac -literally-:ALK and NiMH both.  Pretty
severe manufacturing issues, though the details about the
contamination weren't spelled out.  No CPSC issues though, so they're
still in business.

It got so bad that Rayovac has to put a banner on all retail blister
packs:  "Lasts As Long As Duracell" or some such.

Everyone seems pretty pleased with the Eneloops, so that's good.  I
used them on the KX3 for a while, then ran a few tests and ended up
with Tenergy Premium.  To each his own!

73,

>Correct, Matt.  I am actually running Panasonic HHR210AAB cells right now, which appear to be Enelooops with a different jacket, based on my research.  We used them in my work, but only recharged them a few times, so I was able to get them cheap, and they work well.  I have a lot of experience with Eneloop 2000 maH cells at home...probably a more severe environment than my work!  They seem to be very forgiving so long as you don't discharge them below 0.9 volts per cell.
