Why do batteries go dead in an unused flashlight while the rest of the batteries still in the pack stay good?

what an interesting question.
did a bit of research. fun papers like: https://www.researchgate.net/publication/257172972_Self-discharge_characteristics_of_a_metal_hydride_electrode_for_Ni-MH_rechargeable_batteries
main factors seem to be: temperature.
maybe the pack is cooler?
I mentioned elsewhere a theory of increased electron migration due to the large surface area of the connected circuit. Can't find any papers on that but am happy to do the experiment and publish if someone wants to pay for it

Already known. But i like your way of transporting general physics knowledge to the public.
