Mallory * has been running a Duracell commercial showing technicians working
in wind towers. They're using what are said to be "high-voltage" meters, but
which appear to be clamp-on ammeters. We're told these meters "keep them
safe", and they therefore rely on Duracell /rechargeable/ batteries.

Hello? If I need an electronic device to keep me safe, the /last/ thing I
want powering it is rechargeable batteries. Rechargeables can poop out when
you most need them. Alkaline primaries decline slowly, so I can easily see
when they're near the end, and replace them in good time.

* The company long ago changed its name to Duracell, but it will always be
Mallory to me, just as their competitor will always be Eveready. (Or Union
Carbide, for that matter.)
