Four examples of each model are tested in each of the two tests.

Thanks for that feedback.
When multiplied by the number of different batteries tested, it’s likely any generic industry wide lack of quality control would soon be apparent. Enough to encourage the testers to increase the sample sizes to identify if it is brand or type specific.
I found the tests interesting enough to stop buying expensive dry cells, with one or two special instances, and now purchase quality rechargable batteries instead.
Note:
The use in marketing batteries of ‘lasts longer’ should possibly be banned. Rechargable batteries are packaged and labelled by their capacity. The same should be universal for dry cells, set against a standard discharge rate. Nothing new that the manufacturers don’t already use as a benchmark for batch testing at the factory.
And yes to those who know otherwise, in this instance four of one kind is not a significant sample size!

It sounds as though they are tested individually; maybe CHOICE could consider testing a battery of batteries (e.g. four) to see what variances may arise in a multi-battery device’s discharge pattern(s).
I must also note that with age (and with double entendre very deliberate), discharge can become much more variable.
