Which battery has the higher Ampere-Hour rating?

Explanation:
Ampere-Hour rating shows how much energy a battery can store and deliver over time. The APU battery is designed to provide enough energy to crank the APU and sustain essential electrical loads during start, which requires a larger energy capacity. This is why it’s built with a higher Ah rating compared to the other batteries, whose roles are backup, emergency power, or short-duration needs. The reserve battery is intended for emergency use and is kept small, while the auxiliary and main batteries handle their specific functions but don’t need as much total energy storage as the APU battery.
