One AA cell has suddenly turned grey underneath the transparent

Under normal circumstances I would just throw it away but these are
not normal circumstances (I´m about 8000 miles away from my stash of
spare batteries and over here I´m not allowed out to buy any more) so
I´d like to keep using it for as long as it holds a charge if it is
safe to do so and it will not ruin my equipment.

Any thoughts about whether this might be just corrosion on the outside
of the can or might it be leaking chemicals or is something else
happening?

Thanks!

Seems to be going okay so far....

I think Pamela is right, it is a leak and on its way out but in your
circumstances I would probably keep going. The sleeves seem pretty
robust. I don't think it is likely to overhead and blow up like a
Lithium Ion.

How valuable is the kit, and do you stop earning if you stop using it?

If it is a preamp for a guitar active pickup (say) then the worst
consequences of failure might be corrosion and a requirement to replace
the battery box. Hard to see how it would destroy a guitar but it might
wipe out something more compact, say a radio mic.

Is "over here" somewhere that you can't even order stuff online? Can you
get "ordinary" AA's? Assuming it is in a multi battery rig then the
"extra" 0.3 volts if you replace just one is unlikely to fry anything.
