different voltages.
nimh/nicad rechargeable batteries have a nominal voltage of ~1.2v/cell,
alkaline batteries are ~1.5v/cell and non-rechargeable lithium
batteries are ~1.6v/cell.
recent devices normally work with all three types, especially if only
just one or two batteries is needed, where the difference in voltage is
small.
however, some older devices, especially ones that use several
batteries, may fail to function due to the lower voltage of nimh, or
possibly be damaged by the higher voltage of lithium batteries.
i have an old nikon flash that is designed to use six 1.5v alkaline
batteries (9v), but with nimh rechargeable batteries, it's only 7.2v,
which is enough of a difference so that the flash does not work at all.

he has photos of books about vacuum tubes/valves.
what more is there to know?
