??? What are you checking in the unit ?

The problem as I see it is that accelerated testing a battery using
higher discharge currents probably isn't going to tell you much. The
actual application current is so low that it's affected by factors other
than simply the Ah rating. The 10uA curve

is going to be a good guide, IMHO

Possibly you might get some idea by investigating products that
use that level of current. For example, RTCC chips in PCs. How
much current do they use and how long does a battery last ? It's
going to be less than 3uA, perhaps 5-6 years, and maybe a
guesstimate can put your product longevity between RTCC chips
and the 10uA plot

I think you should also be definitely seeking manufacturer's advice
