I would get an ordinary car starter battery. They are designed for delivery lots of amps.I have a procharge ultra battery charger, which has different settings for AGM and sealed lead acid (which all my engine room batteries are) - won't it cause issues if I just change the bow thruster battery to AGM?
AGM will be more expensive, and I doubt you will see any advantage.
Leisure batteries are a compromise, and have less good CCA specs. They will have high Ah capacities.
There is a lot to be said for having the same kind of batteries everywhere so you don't need separate chargers.
