I have some unanswered questions from preparing the article series for you E.E. or electronics hobbyist types out there. Here’s the first:

Since super-premium alkaline batteries offer more capacity than lithium cells, and since lithiums cost perhaps five times as much as alkalines, might power management circuitry eventually compensate for alkaline battery voltage roll-off such that alkaline performance might equal or better that of lithiums? (Ignoring low-temperature performance.)
