'Trojan' 6V 225AH deep cycle flooded you're saying?
Sounds suspiciously like Century C105:

Something interesting is look at the weight, size and capacities of the industrial range compared to the automotive versions of 'deep cycle' batteries.
Those weighs nearly 30kg a pop - there is a lot of lead in that.
There is a lot of conjecture about AGM batteries - Optima D34 is a favorite on this forum for use in Falcons, they halve their charging capacity at above 60 degrees ambient temperatures and virtually stop charging once they reach 80 degrees, AGM isn't ideal for under bonnet applications, especially when you have a bigass turbo in the engine bay in a modified XR6T and you beat on it.
I guess if its a garage queen and it sits on float charge 24/7 then its fit for purpose but for a daily, not ideal.
AGM is a good option for house batteries on a boat, a secondary deep cycle in the back of a 4x4 or a car with a battery in the boot like Euros or VE/VF Commodore.
If you have a Falcon as a daily - Century 67EF MF, is locally made and 640CCA with a 3 year warranty:
