Storing Zinc-Air Batteries in the Fridge

I like to buy my hearing aid batteries in bulk. I heard somewhere that
you should store batteries in the refridgerator. Does this work with
zinc-air batteries?

Thanks

I don't think there is any need to. They are dormant until unsealed.

As Mr Woody says, probably not.

You might also run into problems with moisture contamination. Also the seal
might be disrupted by extremes of temperature.

Try and find a data-sheet for your batteries. Somewhere it will give
recommended storage and operating temperature ranges.

Oh, you'd also look a bit silly walking around with a fridge on your head.

How dormant?
Is it reasonable to expect to store them for years?

I stored some of mine at room temperature for 2 years before I got the
supply and demand matched. I had one or two duds, but I put that down to
less than perfect sealing. I'm using some now that have been stored for
nearly a year.

Oh use common sense. That's hard.

How would I look with solar cell earings?

Thanks I'll just leave them at room temperature then.

I've gotten some bad ones in the past year or two. One was dead
from the moment I pulled the strip off. I was buying from Radio Shack
for years, and then switched to Duracell because they became easier
to get. It almost seems like there are bad batches, since one pack is
fine, and then the next has two or three out of six less than perfect.
An occasional one, I'd just think I left things running. But if I put
one in and it lasts a week when I expect two to three weeks (known from
years of recording how long a battery lasts), and then it happens with
the replacement from the same pack, something seems odd.

All have been bought "fresh" at the store, so I sure haven't had
them around for a long time.

I use the Renata ones from Mouser. I don't think I save much but I
hate running out of them.

Very likely the seals are not keeping the air out.

On another tack.
Can you put a load on Zinc-Air with the tab on, then remove the tab
some time later, if you need a one-shot device?

I just took time off from cooking dinner to measure six unused (sealed)
cells. These are dated 2002-11-07 (7 November), and measure 1.37 V, a
bit lower than the activated voltage. I guess that while sealed their
internal resistance is very high, *** but I don't know for sure***.

A cell with a faulty seal will presumably measure 1.5 V with the seal in
place, unless it has already self-discharged.

I once pulled the tab on one about a week before I needed it (by accident),
and I'm pretty sure that one did not last as long as I expected.

I'm not prepared to pull the tabs on purpose, so I can't give anything
further.
