A small to medium size cruise ship has an engine at around 24'000 HP ≈ 176 MW.
The smallest terminal you can connect to a AAA battery is the same diameter as 00 AWG copper wire.
Provided that the engine has 100% efficiency and can turn 176MW of electricity into torque, to safely run power it needs through that 00 AWG wire, the battery would need to provide a voltage of at least 70 kV.
