Which brings up something I've always wondered about. You
go in the store and there is a very nice battery display
rack with all sorts of batteries. One can only speculate
how long they have been on the rack, or in storage before
being displayed on the rack.

Does the store scrap any battery that has been on the rack
for X months? Years? Or just keep them until someone buys
them?

And which brings up another question - how do you know that
your source is any better?

I don't. In fact I don't even worry about the price of a small
battery. It was just something that came to mind the other day
while I was waiting in line at Home Pro. Right there by the
cash register they had a big rack of batteries, must have been
a hundred of them.

I came across a pile of dead batteries that I had saved when I
was trying to be green before I learned that I had to drive five
miles to dispose of these button cells. They were Sony and
something called Renata. I didn't find any of those Panasonic but
the sheet they come on is unmistakable. I remember tearing the
last two out of that sheet to try to use in the transmitter unit
only to discover them dead.


What was the expiration year on those?

Hell if I know. On the non-writing side there is a 72 on one and a 58
on the other. Since they weren't made in those years that sure
couldn't be an expiration date.


It's on the back of the package, a "Use by" date:

What impresses the heck out of me is the HP-11C pocket calculator and
some digital thermometers that use the same sort of battery, type 357.
All those devices are from the 80's and are now on the 2nd set of batteries.
