Alternators have to be supplied with a sufficient current from the
battery in order to generate the larger currents required by the
aircraft systems.


This is a new concept to me, can you elaborate?

My understanding of alternators is that mechanical energy from the
engine causes the alternator to spin, which then powers aircraft
components and (when regulated correctly) can recharge the battery.

Is there something about aircraft alternators that requires the battery
to power them (rather than the other way around)?


Yes, they need a little charge in the battery to start charging
themselves. Absolutely dead battery? Alternator is useless.
