In an emergency power scenario when operating solely on batteries, how many minutes of battery life does each APU start attempt consume?

Explanation:
When operating on battery power, every start attempt uses up a fixed portion of the remaining battery life because starting the APU requires a large electrical surge to spin it up and bring it online. The scenario treats a single APU start attempt as consuming six minutes of battery life, which represents that energy draw in a compact, memorable amount. Knowing this, you can budget your remaining battery time to decide how many start attempts you can afford while still keeping essential systems powered. The other minute values don’t match the typical energy draw assumed for an APU start in this emergency-battery context, so six minutes is the standard figure.
