Me too, since the message I left is a distillation of what I've been told by
various people connected with battery manufacturers (mostly, but not only,
Varta). If a particular battery maker states that a particular battery should
operate well within a range of temperatures, then I'd be willing to live with
that. In general, though, I'd be tempted to *not* freeze a battery (the amount
of shelf-life gained seems insignificant compared to the potential for ruining
the battery). Refrigeration, regardless of info source, has never been
indicated to me to be a problem.
