And a fully discharged AAA cell can kill you if fired from a gun. Or if you
eat enough of them.
Not at all. It's a good idea, at least, to know how to rig up a current
limiter, especially when it can be built for less than the cost of one of
the batteries. It could prolong their life in the case of an accidental
short circuit or overload, and it would be very much advisable for Lithium
batteries which can explode if short-circuited.
Here's a link to a somewhat technical analysis of low voltage hazards.
It is probably an overkill answer to the OP's question, but it is
readable and provides a scientific basis for its conclusions.
