A good approximation (for all chemical reactions) is half the rate for
every 8 deg C drop, so by keeping them in a fridge at about 5 deg C you
can reduce that to about 2.5%. Not sure what effect freezing has but
I'd imagine it would be much more dramatic (but pointlessly so if the
cell is damaged as a result).

Or just keep them in their blister packs inside a grip-strip polythene
bag so the airborne moisture doesn't get to them.
